OnSite Model 3210 Series overview
The OnSite Model 3210 Series G.SHDSL VPN Router (see figure 1) is a next generation business-class
G.SHDSL router that addresses both the security and the traffic prioritization needs of enterprises while providing complete broadband integration with existing DSLAM neteworks. VPN routers enable the secure communication between remote offices, home offices, and mobile users across insecure IP networks such as the
Internet. The 3210 takes it one step further and integrates quality of service (QoS).
Figure 1. OnSite G.SHDSL VPN Router
The Model 3210 provides two 10/100Base-T Ethernet ports and one G.SHDSL port to deliver a managed virtual-private-network (VPN) connection over the Internet or any unsecured IP network.
The OnSite 3210 Router supports Frame-Relay and PPP networking with VPN and firewall functionality.
Authentication and firewall services protect against unauthorized users while encryption, and anti-replay capabilities preserve data confidentiality. Patton's powerful CoS and QoS mechanisms provide traffic-shaping and
prioritization to guarantee your mission-critical data is delivered promptly and unimpeded by traffic from
other users on the same LAN. Besides assuring first priority for key information, Patton's advanced QoS technology enhances the quality and clarity of realtime application such as live voice and video communications
with the main office. These compact VPN Routers support PPP/PPPoE and Frame Relay services over the
serial WAN link.
The OnSite VPN Router performs the following major functions:
• Routed LAN-to-WAN connectivity between two 10/100 Ethernet LAN ports and one G.SHDSL port.
• IP Routing with class-of-service/quality-of-service (CoS/QoS) support for Internet or IP-WAN access with
traffic shaping and prioritization.
• VPN tunneling for secure traversal of unsecured IP networks
• IPSec payload encryption with authentication header (AH, specified in RFC 2402) and encapsulating secu-
rity payload (ESP, specified in RFC 2406) protects data integrity and confidentiality and prevents unauthorized data-replay.

OnSite Model 3210 User Manual 1 • General information
Applications overview
Patton’s OnSite managed VPN routers deliver the features you need for secure, optimized communication
over non-secured IP networks. Combining VPN tunneling, standard IPSec encryption, and firewall capabilities with Patton’s powerful quality of service technology, OnSite VPN routers deliver private, prioritized networking for business, government, and military applications.
Banking, insurance, retail, utilities, railroads, or government, any organization with more than one site can
benefit from the security and traffic-shaping advantages of the OnSite family of VPN routers. As traffic
traverses unsecured networks, VPN tunneling with standard IPSec encryption plus firewall capabilities preserve
data security and integrity. Meanwhile, OnSite’s ToS/Qos traffic-shaping and prioritization prevent critical
information getting blocked or impeded by less important traffic while enhancing the quality of real-time
applications such as voice and video.
OnSite 3210 Series models provide dual 10/100Base-T Ethernet ports with a G.SHDSL port. The two Ethernet ports provide full-featured IP routing plus Ethernet and IP-layer QoS services. The G.SHDSL port provides WAN access by means of a leased-line connection to the network. The following sections show some
typical applications for the OnSite 3210 Series.
This chapter describes typical applications for which the OnSite 3210 Series series is uniquely suited.
Branch-Office virtual private network over Frame Relay service
Featuring VPN tunneling combined with built-in frame-relay support and a selection of standard serial interfaces on-board, the OnSite 3210 Series offers the remote-branch office a secure, private and prioritized network connection to another location over virtually any available network service and any standard WAN
interface.
Figure 5. Branch-office virtual private network over a Frame-Relay service network
Figure 5 shows a branch-to-branch VPN connection through a frame-relay service network as delivered on
serial lines. The OnSite 3210 Series can support a similar scenario with network service delivered via an Ethernet WAN interface. For remote sites where PPP service is available, the 3210 Series also supports PPP network
access over all the standard WAN interface options mentioned above.
In this specific application, all traffic between the branch and corporate offices is carried in an IPSec tunnel. All
of the IPSec VPN traffic is encapsulated in Frame Relay for transport over the Frame Relay service network.
The serial port is configured for Frame Relay.
Applications overview 20
Page 21
OnSite Model 3210 User Manual 1 • General information
To configure this application, you need to configure the following features:
• The WAN port with Frame Relay as the encapsulation protocol
• An IPSec VPN between the two endpoints.
See chapter 4 on page 40 to configure the serial port and chapter 5 on page 42 to configure the VPN.
Corporate multi-function virtual private network
The OnSite 3210 Series can deliver both private corporate intranet service and public Internet access to multiple remote sites by leveraging OnSite’s multiple frame-relay PVC support (see figure 6). The enterprise enjoys
the benefits of secure multi-office virtual private networking with QoS for prioritized traffic flow for missioncritical information.
Figure 6. Corporate multi-function virtual private network
In figure 6, the blue pipes represent VPN connections for private traffic within the corporate intranet, while
the green pipes represent the Internet traffic. The red pipe is a Frame Relay PVC transporting Internet traffic
and private corporate traffic over the VPN. Each of the three remote sites is connected with headquarters via an
OnSite VPN router. Each remote site can take advantage of the most convenient and locally available interface
the WAN service can offer.
Applications overview 21
Page 22
OnSite Model 3210 User Manual 1 • General information
The corporate multi-function application carries two types of traffic between each remote office and corporate’s central office:
• Private corporate traffic (the intranet/extranet)
• Internet traffic
The service provider offers a Frame Relay network for access, so both the private corporate traffic and the Internet traffic is transported over a Frame Relay PVC with one DLCI. The corporate traffic is transported within
IPSec VPN that is in the Frame Relay PVC. The separation of corporation and Internet traffic is managed by
using an ACL using IP addresses as the watershed.
To configure this application, you must configure the following features:
• A serial Frame Relay link as the WAN service which will carry both private corporate traffic and public
Internet traffic
• An IPSec VPN for private corporate traffic
• An ACL to distinguish between the two types of traffic so only the private corporate traffic is carried over
the VPN.
See chapter 4 on page 40 to configure the serial port, chapter 5 on page 42 to configure the VPN, and chapter
6 on page 54 to configure the ACL. Chapter 7 on page 68 provides more in-depth explanations of scheduling
various types of traffic. Various techniques are also described, including QoS and TOS.

To ping outside your local LAN, you will need to configure the
default gateway.
3. Load configuration
Patton provides a collection of configuration templates online at www.patton.com/support/upgrades—one
of which may be similar enough to your application that you can use it to speed up configuring the OnSite
router. Simply download the configuration note that matches your application to your PC. Adapt the configuration as described in the configuration note to your network (remember to modify the IP address) and copy
the modified configuration to a TFTP server. The OnSite VPN Router can now load its configuration from
this server.
In this example we assume the TFTP server on the host with the IP address 172.16.1.11 and the configuration
named IPL.cfg in the root directory of the TFTP server.

Next, you will need to create a WAN profile, create a WAN interface, and create a subscriber. Then, you can
configure the DSL port (port dsl 0 0) for PPPoE.
Follow this example:
profile napt WAN
context ip router
interface WAN

port dsl 0 0
pvc vpi 8 vci 35
pppoe
session MyISP
bind subscriber MySubscriber
no shutdown
The line -
use profile napt WAN -
defines that the NAPT profile <profile> will be used on the ip interface
<name>. For PPPoE, you will only use outbound for identification. You will want to use authentication, which
is why you bind to a subscriber. You can use authentication chap or authentication pap. The line -
scriber MySubscriber
- binds the PPPoE session to the PPP subscriber, in case authentication is required. If
bind sub-
you do not use authentication, then you will not have a subscriber and you will bind directly to the interface.
Configuration Summary
The modems offer multiple bridged Ethernet connections through logical channels within the DSL link. A
logical connection is called a Permanent Virtual Circuit (PVC) and is identified by a VPI/VCI number pair.
Consult your provider's configuration instructions for connections used on your DSL link. You define those
PVCs inside "port dsl 0 0":
port dsl 0 0
pvc vpi 8 vci 35
Iin the mode "pvc", you define what to do with the bridged Ethernet connection it offers:
• Bind one or more IP interfaces when your providers uses fixed ip addresses or DHCP in the network
• Enter PPPoE mode and define a PPP session if the provider is using PPPoE.
Note
PPPoA is not supported.
Configuration Summary 39
Page 40
OnSite Model 3210 User Manual 4 • G.SHDSL Basic Configuration
Setting up permanent virtual circuits (PVC)
The modems currently available are using ATM to multiplex traffic over the DSL framing connection. ATM
allows you to have separate logical connections running in parallel. Those connections are called permanent
virtual circuits (PVC). All permanent virtual circuits use AAL5 framing.

select either LLC encapsulation or VC multiplex
ing for this PVC.
Default: llc
Using PVC channels in bridged Ethernet mode
The PVC offers a bridged Ethernet connection as specified in RFC1483, which can be used as an IP link e.g.
with DHCP to assign the address, DNS server, and default gateway. To do this, you bind an IP interface to the
PVC like it would be done to a normal Ethernet port.

Using PVC channels with PPPoE
The RFC1483 bridged Ethernet connection can also be used for PPPoE. To do this, you enter PPPoE mode
within the PVC mode. All PPPoE commands apply as if the PVC was a regular Ethernet port.

Troubleshooting DSL Connections
Link State:
• Verify that the DSL link is established (status LED is continuously on)
PPPoE access:
• Check if "show pppoe detail 3" shows "State: .... opened". This indicates that the PVC is valid and a that
you reached a PPPoE server through it.
• Check if "show ppp networks detail 3" shows "State: .... opened" for both the "LCP" and the "CHAP" sec-
tion. If LCP is not working, there is probably no compatible authentication protocol configured. Make sure
"authentication chap" and "authentication pap" are included in the subscriber setup. If only CHAP failed
there may be an error with the username or password.
• Run the “debug” command: node# debug dsl-setup (See table 10 above).

Introduction
This chapter describes how to configure the VPN connections between two OnSite routers or between an
OnSite and a third-party device.
A virtual private network (VPN) is a private data network that uses the public telecommunications infrastructure, maintaining privacy through the use of a tunneling protocol and security procedures.
There are different technologies to implement a VPN. OnSite applies the internet protocol security (IPsec)
Architecture (see RFC 2401). The following sections describe the main building blocks of the IPsec architecture as implemented in OnSite router.
Authentication
Authentication verifies the integrity of data stream and ensures that it is not tampered with while in transit. It
also provides confirmation about data stream origin.
Two authentication protocols are available:
• Authentication header (AH): protects the IP payload, the IP header, and the authentication header itself
• Encapsulating security payload (ESP): protects the IP payload and the ESP header and trailer, but not the
IP header
Two algorithms perform the authentication:
• HMAC-MD5-96: is a combination of the keyed-hashing for message authentication (HMAC) and the message
digest version 5 (MD5) hash algorithm. It requires an authenticator of 128-bit length and calculates a hash
of 96 bits over the packet to be protected (see RFC 2403).
• HMAC-SHA1-96: is a combination of the (HMAC) and the secure hash algorithm version 1 (SHA1). It
requires an authenticator of 160 bit length and calculates a hash of 96 bits over the packet to be protected
(see RFC 2404).
Encryption
Encryption protects the data in transit from unauthorized access. Encapsulating security payload (ESP) is the
protocol to transport encrypted IP packets over IP (see RFC 2406).
The following encryption algorithms are available:
Key Length [Bit] RFC
DES-CBC (Data Encryption Standard - Cipher Block Chaining) 56 2405
3DES-CBC (Triple Data Encryption Standard - Cipher Block Chaining)
AES-CBC (Advanced Encryption Standard - Cipher Block Chaining) 128, 192, or 256 3268
a. The 3DES algorithm uses only 112 out of the 128 Bit or 168 out of the 192 Bit as key information. Cisco
only supports 192 Bit keys with 3DES.
128 or 192
a
1851
The single DES algorithm no longer offers adequate security because of its short key length (a minimum key
length 100 bits is recommended). The AES algorithm is very efficient and allows the fastest encryption. AES
with a key length of 128 bits is therefore the recommended algorithm.
Introduction 43
Page 44
OnSite Model 3210 User Manual 5 • VPN configuration
Transport and tunnel modes
The mode determines the payload of the ESP packet and hence the application:
• Transport mode: Encapsulates only the payload of the original IP packet, but not its header, so the IPsec
peers must be at the endpoints of the communications link.
• A secure connection between two hosts is the application of the transport mode.
• Tunnel mode: Encapsulates the payload and the header of the original IP packet. The IPsec peers can be
(edge) routers that are not at the endpoints of the communications link.
A secure connection of the two (private) LANs, a ‘tunnel’, is the application of the tunnel mode.
VPN configuration task list
To configure a VPN connection, perform the following tasks:
• Creating an IPsec transformation profile
• Creating an IPsec policy profile
• Creating/modifying an outgoing ACL profile for IPsec
• Configuration of an IP Interface and the IP router for IPsec
• Displaying IPsec configuration information
• Debugging IPsec
Creating an IPsec transformation profile
The IPsec transformation profile defines which authentication and/or encryption protocols, which authentication and/or encryption algorithms shall be applied.
Procedure: To create an IPsec transformation profile

OnSite Model 3210 User Manual 5 • VPN configuration
Creating an IPsec policy profile
The IPsec policy profile supplies the keys for the encryption and/or the authenticators for the authentication,
the security parameters indexes (SPIs), and IP address of the peer of the secured communication. Furthermore,
the profile defines which IPsec transformation profile to apply and whether transport or tunnel mode shall be
most effective.
The SPI identifies a secured communication channel. The IPsec component needs the SPI to select the suitable
key or authenticator. Inbound and outbound channels can have the same SPI, but the channels in the same
direction—inbound or outbound—must have unique SPIs. The SPI is not encrypted and can be monitored.

digits (0..9, A..F); one digit holds 4 Bit of key
information.
The key setting must match definitions in the
respective IPsec transformation profile. In particular, the length of the key or authenticator must
match the implicit (see section
on page 43 and
“Encryption”
“Authentication”
on page 43) or
explicit specification.
Keys must be available for inbound and out-
bound directions. They can be different for the
two directions. Make sure that the inbound key
of one peer matches the outbound key of the
other peer.
4 node(pf-ipstr)[name]#spi
{ inbound | outbound } { ah | esp } spi
Sets the SPI for encryption (esp) or authentication
(ah), either for inbound or outbound direction.
The SPI shall be a decimal figure in the range

1..2
–1.
SPIs must be available for encryption and/or
authentication as specified in the respective IPsec
transformation profile.
SPIs must be available for inbound and outbound
directions. They can be identical for the two
directions but must be unique in one direction.
Make sure that the inbound SPI of one peer
matches the outbound SPI of the other peer.
5 node(pf-ipstr)[name]#peer ip-address Sets the IP address of the peer

Creating/modifying an outgoing ACL profile for IPsec
An access control list (ACL) profile in the outgoing direction selects which outgoing traffic to encrypt and/or
authenticate, and which IPsec policy profile to use. IPsec does not require an incoming ACL.
Note
Outgoing and incoming IPsec traffic passes an ACL (if available)
twice, once before and once after encryption/authentication. So the
respective ACLs must permit the encrypted/authenticated and the
plain traffic.
For detailed information on how to set-up ACL rules, see chapter 6, “Access control list configuration” on
page 54.
Procedure: To create/modify an outgoing ACL profile for IPsec
Mode: Configure
Step Command Purpose
1 node(cfg)#profile acl name Creates or enters the ACL profile name
2 node(pf-ipstr)[name]#permit ...
[ ipsec-policy name ]
The expression ‘ipsec-policy name’ appended to a
permit ACL rule activates the IPsec policy profile
name to encrypt/authenticate the traffic identified
by this rule.
Note
New entries are appended at the end of an ACL. Since the position in
the list is relevant, you might need to delete the ACL and rewrite it
completely.
Example: Create/modify an ACL profile for IPsec
The following example configures an outgoing ACL profile that interconnects the two private networks
192.168.1/24 and 172.16/16.
3210(cfg)#profile acl VPN_Out

Configuration of an IP interface and the IP router for IPsec
The IP interface that provides connectivity to the IPsec peer, must now activate the outgoing ACL profile configured in the previous section. Furthermore, the IP router must have a route for the remote network that
points to the respective IP interface.
Procedure: To activate the outgoing ACL profile and to establish the necessary route

Creates a route for the remote network that
points the above IP interface if-name
You can omit this setting if the default route
already points to this IP interface or to a next hub
reachable via this IP interface, and if there is no
other route.
Make also sure that the IP router knows how to
reach the peer of the secured communication.
Usually, a default route does this job.
Example: Activate outgoing ACL and establish route
The following example configures an outgoing ACL profile that interconnects the two private networks
192.168.1/24 and 172.16/16.

OnSite Model 3210 User Manual 6 • Access control list configuration
Introduction
This chapter provides an overview of IP Access Control Lists and describes the tasks involved in configuring
them through the OnSite router.
This chapter includes the following sections:
• About access control lists
• Access control list configuration task list (see page 57)
• Examples (see page 67)
About access control lists
This section briefly describes what access lists do, why and when you should configure access lists, and basic
versus advanced access lists.
What access lists do
Access lists filter network traffic by controlling whether routed packets are forwarded, dropped or blocked at
the router's interfaces. Your router examines each packet to determine whether to forward or drop the packet,
based on the criteria you specified within the access lists.
Access list criteria could be the source address of the traffic, the destination address of the traffic, the upperlayer protocol, or other information.
Note
Sophisticated users can sometimes successfully evade or fool basic
access lists because no authentication is required.
Why you should configure access lists
There are many reasons to configure access lists. For example, you can use access lists to restrict contents of
routing updates, or to provide traffic flow control. But one of the most important reasons to configure access
lists is to provide security for your network, and this is the reason explored in this chapter.
You should use access lists to provide a basic level of security for accessing your network. If you do not configure
access lists on your router, all packets passing through the router could be allowed onto all parts of your network.
Introduction 55
Page 56
OnSite Model 3210 User Manual 6 • Access control list configuration
For example, access lists can allow one host to access a part of your network, and prevent another host from
accessing the same area. In figure 14 host A is allowed to access the Human Resources network and host B is
prevented from accessing the Human Resources network.
Host A
Node

Host B

Resource

Research &
Development
Network
You can also use access lists to decide which types of traffic are forwarded or blocked at the router interfaces.
For example, you can permit e-mail traffic to be routed but at the same time block all Telnet traffic.
When to configure access lists
Access lists should be used in firewall routers, which are often positioned between your internal network and an
external network such as the Internet. You can also use access lists on a router positioned between two parts of
your network, to control traffic entering or exiting a specific part of your internal network.
To provide the security benefits of access lists, you should configure access lists at least on border routers, i.e.
those routers situated at the edges of your networks. This provides a basic buffer from the outside network or
from a less controlled area of your own network into a more sensitive area of your network.
On these routers, you should configure access lists for each network protocol configured on the router interfaces.
You can configure access lists so that inbound traffic or outbound traffic or both are filtered on an interface.
Features of access control lists
The following features apply to all IP access control lists:
• A list may contain multiple entries. The order access of control list entries is significant. Each entry is pro-
cessed in the order it appears in the configuration file. As soon as an entry matches, the corresponding
action is taken and no further processing takes place.
About access control lists 56
Page 57
OnSite Model 3210 User Manual 6 • Access control list configuration
• All access control lists have an implicit deny ip any any at the end. A packet that does not match the criteria
of the first statement is subjected to the criteria of the second statement and so on until the end of the access
control list is reached, at which point the packet is dropped.
• Filter types include IP, Internet Control Message Protocol (ICMP), Transmission Control Protocol (TCP),
User Datagram Protocol (UDP), and Stream Control Transmission Protocol (SCTP).
• An empty access control list is treated as an implicit deny ip any any list.
Note
Two or more administrators should not simultaneously edit the configuration file. This is especially the case with access lists. Doing this
can have unpredictable results.
Once in access control list configuration mode, each command creates a statement in the access control list.
When the access control list is applied, the action performed by each statement is one of the following:
• permit statement causes any packet matching the criteria to be accepted.
• deny statement causes any packet matching the criteria to be dropped.
To delete an entire access control list, enter configuration mode and use the
form of the
profile acl
com-
no
mand, naming the access list to be deleted, e.g. no profile acl name. To unbind an access list from the interface
to which it was applied, enter the IP interface mode and use the
no
form of the access control list command.
Access control list configuration task list
To configure an IP access control list, perform the tasks in the following sections.
• Mapping out the goals of the access control list
• Creating an access control list profile and enter configuration mode (see page 58)
• Adding a filter rule to the current access control list profile (see page 58)
• Adding an ICMP filter rule to the current access control list profile (see page 60)
• Adding a TCP, UDP or SCTP filter rule to the current access control list profile (see page 62)
• Binding and unbinding an access control list profile to an IP interface (see page 64)
• Displaying an access control list profile (see page 65)
• Debugging an access control list profile (see page 65)
Mapping out the goals of the access control list
To create an access control list you must:
• Specify the protocol to be filtered
• Assign a unique name to the access list
• Define packet-filtering criteria
A single access control list can have multiple filtering criteria statements.
Access control list configuration task list 57
Page 58
OnSite Model 3210 User Manual 6 • Access control list configuration
Before you begin to enter the commands that create and configure the IP access control list, be sure that you
are clear about what you want to achieve with the list. Consider whether it is better to deny specific accesses
and permit all others or to permit specific accesses and deny all others.
Note
Since a single access control list can have multiple filtering criteria
statements, but editing those entries online can be tedious. Therefore,
we recommend editing complex access control lists offline within a
configuration file and downloading the configuration file later via
TFTP to your OnSite device.
Creating an access control list profile and enter configuration mode
This procedure describes how to create an IP access control list and enter access control list configuration mode
Mode: Administrator execution
Step Command Purpose
1 node(cfg)#profile acl name Creates the access control list profile name and enters the configura-
tion mode for this list
name is the name by which the access list will be known. Entering this command puts you into access control list
configuration mode where you can enter the individual statements that will make up the access control list.
Use the
no
form of this command to delete an access control list profile. You cannot delete an access control
list profile if it is currently linked to an interface. When you leave the access control list configuration mode,
the new settings immediately become active.
Example: Create an access control list profile
In the following example the access control list profile named WanRx is created and the shell of the access control list configuration mode is activated.
3210>enable
3210#configure
3210(cfg)#profile acl WanRx
3210(pf-acl)[WanRx]#

Introduction
This chapter describes how to use and configure the OnSite Quality of Service (QoS) features. Refer to 6,
“Access control list configuration” on page 54 for more information on the use of access control lists.
This chapter includes the following sections:
• Quick references (see page 73)
• Packet Classification (see page 75)
• Assigning bandwidth to traffic classes (see page 73)
• Link scheduler configuration task list (see page 74)
QoS in networking refers to the capability of the network to provide a better service to selected network traffic.
This chapter shows you how to configure the OnSite router to best use the access link.
In many applications you can gain a lot by applying the minimal configuration found in the quick reference
section, but read sections “Applying scheduling at the bottleneck” and “Using traffic classes” first to understand the paradox of why we apply a rate-limit to reduce delay and what a “traffic-class” means.
Configuring access control lists
Packet filtering helps to control packet movement through the network. Such control can help to limit network traffic and to restrict network use by certain users or devices. To permit or deny packets from crossing
specified interfaces, the OnSite 3210 provides access control lists.
An access control list is a sequential collection of permit and deny conditions that apply to packets on a certain
interface. Access control lists can be configured for all routed network protocols (IP, ICMP, TCP, UDP, and
SCTP) to filter the packets of those protocols as the packets pass through an OnSite 3210. The 3210 tests
packets against the conditions in an access list one by one. The first match determines whether the OnSite
3210 accepts or rejects the packet. Because the OnSite 3210 stops testing conditions after the first match, the
order of the conditions is critical. If no conditions match, the software rejects the address.
For information and examples on how configure access control lists, refer to chapter 6, “Access control list con-
figuration” on page 54.

Configuring quality of service (QoS)
In the OnSite 3210, the link scheduler enables the definition of QoS profiles for network traffic on a certain
interface, as shown in figure 16. QoS refers to the ability of a network to provide improved service to selected
network traffic over various underlying technologies including Frame Relay, Ethernet and 802.x type networks, and IP-routed networks. In particular, QoS features provide improved and more predictable network
service by providing the following services:
• Supporting dedicated bandwidth
• Improving loss characteristics
• Avoiding and managing network congestion
• Shaping network traffic
• Setting traffic priorities across the network
Applying scheduling at the bottleneck
When an OnSite acts as an access router, the access link is the point where intelligent use of scarce resources
really makes a difference. Frequently, the access link modem is outside of the OnSite and the queueing would
happen in the modem, which does not distinguish between packet types. To improve QoS, you can configure
the OnSite to send no more data to the Internet than the modem can carry. This keeps the modem’s queue
empty and gives the OnSite control over which packet is sent over the access link at what time.
Using traffic classes
The link scheduler needs to distinguish between different types of packets. We refer to those types as “trafficclasses”. You can think of the traffic-class as if every packet in the OnSite has a tag attached to it on which the
classification can be noted. The access control list “stage” (ACL) can be used to apply such a traffic-class name
to some type of packet based on its IP-header filtering capabilities. The traffic-class tags exist only inside the
OnSite router, but layer 2 priority bits (802.1pq class-of-service) and IP header type-of-service bits (TOS field)
Configuring quality of service (QoS) 70
Page 71
OnSite Model 3210 User Manual 7 • Link scheduler configuration
can be used to mark a specific packet type for the other network nodes. By default the traffic-class tag is empty.
Refer to figure 17 on page 71 when using the ACL to classify traffic. It illustrates the sequence of processing
stages every routed packet passes. Only stages that have been installed in the data path with a “use profile...”
statement in the corresponding interface configuration are present. Both an input direction ACL on the receiving interface as well as an output ACL on the transmitting interface can be used to classify a packet for special
handling by the output link scheduler on the transmit interface. But as visible from the figure no ACL can be
used for an input link scheduler.

The QoS features in OnSite are a combination of an access control list (used for packet classification) and a service-policy profile (used by the link arbiter to define the arbitration mode and the order in which packets of
different classes are served).
Introduction to Scheduling
Scheduling essentially means to determine the order in which packets of the different traffic-classes are served.
The following sections describe the ways this arbitration can be done.
Priority
One way of ordering packets is to give priority to one traffic-class and to serve the other traffic-classes when the
first has nothing to send. OnSite uses the priority scheme to make sure that voice packets generated by the
OnSite will experience as little delay as possible.
Weighted fair queuing (WFQ)
This arbitration method assures a given minimal bandwidth for each source. An example: you specify that traffic-class A gets three times the bandwidth of traffic-class B. So A will get a minimum of 75% and B will get a
minimum of 25% of the bandwidth. But if no class A packets are waiting B will get 100% of the bandwidth.
Configuring quality of service (QoS) 71
Page 72
OnSite Model 3210 User Manual 7 • Link scheduler configuration
Each traffic-class is in fact assigned a relative weight, which is used to share the bandwidth among the currently
active classes. Patton recommends that you specify the weight as percent which is best readable.
Shaping
There is another commonly used way to assign bandwidth. It is called shaping and it makes sure that each traffic-class will get just as much bandwidth as configured and not more. This is useful if you have subscribed to a
service that is only available for a limited bandwidth e.g. low delay. When connecting the OnSite to a DiffServ
network shaping might be a required operation.
Burst tolerant shaping or wfq
For weighted fair queuing and shaping there is a variation of the scheduler that allows to specify if a traffic class
may temporarily receive a higher rate as long as the average stays below the limit. This burstiness measure
allows the network to explicitly assign buffers to bursty sources.
When you use shaping on the access link the shaper sometimes has the problem that multiple sources are
scheduled for the same time - and therefore some of them will be served too late. If the rate of every source had
to strictly obey its limit, all following packets would also have to be delayed by the same amount, and further
collisions would reduce the achieved rate even further. To avoid this effect, the OnSite shaper assumes that the
burstiness needed for sources to catch up after collisions is implicitly allowed. Future versions of OnSite might
allow setting the burst rate and bursting size if more control over its behavior is considered necessary.
Burst tolerance has a different effect when used with weighted fair queuing. Think of it as a higher initial rate
when a source device starts transmitting data packets. This allows giving a higher weight to short data transfers.
This feature is sometimes referred to as a service curve.
Hierarchy
An arbiter can either use wfq or shaping to determine which source to serve next. If you want the scheduler to
follow a combination of decision criteria you can combine different schedulers in hierarchy to do a multi-level
arbitration.Hierarchical scheduling is supported in OnSite with service-policy profiles used inside service-policy profiles.In figure 18 an example of hierarchical scheduling is illustrated. The 1

Quick references
The following sections provide a minimal “standard” link scheduler configuration for the case where a
(DSL/cable) modem link is shared for all traffic. You will also find a command cross reference list for administrators familiar with Cisco’s IOS QoS features and having to become acquainted with OnSite QoS configuration.
Setting the modem rate
To match the data multiplexing of different traffic types to the capacity of the access link is the most common
application of the OnSite link scheduler.
1. Create a minimal profile.
profile service-policy modem-512
rate-limit 512 header-length 20 atm-modem
source traffic-class critical_q
priority
2. Apply the profile just created to the interface connected to the modem.

Some explanations:
Quick references 73
Page 74
OnSite Model 3210 User Manual 7 • Link scheduler configuration
• “modem-512” is the title of the profile which is referred to when installing the scheduler
• “rate-limit 512” allows no more than 512 kbit/sec to pass which avoids queueing in the modem.
• “header-length 20” specifies how many framing bytes are added by the modem to “pack” the IP packet on
the link. The framing is taken into account by the rate limiter.
• “atm-modem” tells the rate limiter that the access link is ATM based. This option includes the ATM over-
head into the rate limit calculation. Please add 8 bytes to the header-length for AAL5 in this case.
• “source traffic-class” enters a sub-mode where the specific handling for a traffic-class is described. The list of
sources in the service-policy profile tells the arbiter which “traffic sources” to serve.
• “critical_q” is the traffic-class for the higheest priority packet streams that you have selected.
• “priority” means that packet of the source being described are always passed on immediately, packets of
other classes follow later if the rate limit permits.
Command cross reference
Comparing OnSite with the Cisco IOS QoS software command syntax often helps administrators to straightforwardly configure OnSite devices. In table 11 the Cisco IOS Release 12.2 QoS commands are in contrast
with the respective OnSite commands.

Packet classification
The basis for providing any QoS lies in the ability of a network device to identify and group specific packets.
This identification process is called packet classification. In OnSite access control lists are used for packet classi-
fication.
An access control list in OnSite consists of a series of packet descriptions like “addressed to xyz”. Those descriptions are called rules. For each packet the list of descriptions is sequentially checked and the first rule that
matches decides what happens to the packet. As far as filtering is concerned the rule decides if the packet is discarded (“deny”) or passed on (“permit”). You can also add a traffic-class to the rule and if this rule is the first
matching rule for a packet it is tagged with the traffic-class name.
Link scheduler configuration task list 75
Page 76
OnSite Model 3210 User Manual 7 • Link scheduler configuration
Some types of packets you do not have to tag with ACL. Voice and data packets from of for the OnSite itself
are automatically tagged with predefined traffic-class names: Predefined internal classes for data are:
• local-default—All other packets that originate from the OnSite itself.
• default—All traffic that has not otherwise been labeled.
Creating an access control list
The procedure to create an access control list is described in detail in chapter 6, “Access control list configura-
tion” on page 54.
At this point a simple example is given, that shows the necessary steps to tag any outbound traffic from a Web
server. The scenario is depicted in figure 20. The IP address of the Web server is used as source address in the
permit statement of the IP filter rule for the access control list.

Figure 20. Scenario with Web server regarded as a single source host
A new access control list has to be created. In the example above, the traffic-class that represents outbound
Web related traffic is named Web.
Access control list have an implicit “deny all” entry at the very end, so packets that do not match the first criteria of outbound Web related traffic will be dropped. That is why a second access control list entry—one that
allows all other traffic—is necessary.
This procedure describes creating an access control list for tagging web traffic from the single source host at a
certain IP address.

from all IP addresses is added to the access control list.

3210(pf-acl)[Webserv~]#permit ip host 172.16.1.20 any traffic-class Web
3210(pf-acl)[Webserv~]#permit ip any any
After packet classification is done using access control lists, the link arbiter needs rules defining how to handle the
different traffic-classes. For that purpose you create a service-policy profile. The service policy profile defines how
the link arbiter has to share the available bandwidth among several traffic classes on a certain interface.
Creating a service policy profile
The service-policy profile defines how the link scheduler should handle different traffic-classes. The overall
structure of the profile is as follows:

The template shown above specifies an arbiter with three inputs which we call “sources”: x, y and “default”.
The traffic-class “default” stands for all other packets that belong neither to traffic-class x nor y. There is no
limit on the number of sources an arbiter can have.
Example: Creating a service policy profile
The following example shows how to create a top service-policy profile named sample. This profile does not
include any hierarchical sub-profiles. The bandwidth of the outbound link is limited to 512 kbps therefore the
interface rate-limit is set to 512. In addition weighted fair queuing (wfq) is used as arbitration scheme among
the source classes.

The first line specifies the name of the link arbiter profile to configure. On the second line the global bandwidth limit is set. The value defining the bandwidth is given in kilobits per second. Each service-policy profile
must have a “rate-limit” except if no scheduling is used i.e. the link scheduler is used for packet marking only
(like setting the TOS byte).
How the bandwidth on an IP interface is shared among the source classes is defined on the third line. The
mode command allows selecting between the weighted fair queuing and shaping arbitration mode. The default
mode is wfq - the command shown above can therefore be omitted.
The following lines configure the source traffic-classes. When using weighted fair queuing (wfq) each userspecified source traffic-class needs a value specifying its share of the overall bandwidth. For this purpose the
share command is used, which defines the relative weights of the source traffic-classes and policies.
Link scheduler configuration task list 78
Page 79
OnSite Model 3210 User Manual 7 • Link scheduler configuration
At a some point the source traffic-class default must be listed. This class must be present, because it defines how
packets, which do not belong to any of the traffic-classes listed in the profile are to be handled. When all listed
“traffic-classes” have “priority” the handling of the remaining traffic is implicitly defined and the “default” section can be omitted. Similarly if no scheduling is used i.e. the link scheduler is used for packet marking only
(e.g. setting the TOS byte) the “default” section can also be omitted.

Specifying the handling of traffic-classes
Several commands are available to specify what happens to a packet of a specific traffic-class.
Defining fair queuing weight
The command
share
is used with wfq link arbitration to assign the weight to the selected traffic-class. When
defining a number of source classes, the values are relative to each other. It is recommended to split 100—
which can be read as 100%—among all available source classes, e.g. with 20, 30 and 50 as value for the respective share commands, which represent 20%, 30% and 50%.

Command Purpose
node(src)[name]#share percentage Defines fair queuing weight (relative to other sources) to percent-
age for the selected class or policy name
Defining the bit-rate
The command
rate
is used with shaper link arbitration to assign the (average) bit-rate to the selected source.
When enough bandwidth is available each source will exactly receive this bandwidth (but no more), when
overloaded the shaper will behave like a wfq arbiter. Bit-rate specification for shaper (kilobits).

Defining absolute priority
This command
priority
can only be applied to classes, but not to lower level polices. The class is given absolute
priority effectively bypassing the link arbiter. Care should be taken, as traffic of this class may block all other
traffic. The packets given “priority” are taken into account by the “rate-limit”. Use the command

to
control the amount of “priority” traffic.

Historically those bits had distinct meanings but since they were never consistently applied routers will ignore
them by default. Nevertheless you can configure your routers to handle specific TOS values and OnSite allows

Specifying layer 2 marking
The IEEE ratified the 802.1p standard for traffic prioritization in response to the realization that different traffic classes have different priority needs. This standard defines how network frames are tagged with user priority
levels ranging from 7 (highest priority) to 0 (lowest priority). 802.1p-compliant network infrastructure devices,
such as switches and routers, prioritize traffic delivery according to the user priority tag, giving higher priority
frames precedence over lower priority or non-tagged frames. This means that time-critical data can receive
preferential treatment over non-time-critical data.
Under 802.1p, a 4-byte Tag Control Info (TCI) field is inserted in the Layer 2 header between the Source
Address and the MAC Client Type/Length field of an Ethernet Frame. Table 13 lists the tag components.
Table 13. Traffic control info (TCI) field
Tag Control Fiel d Description
Tagged Frame Type Interpretation Always set to 8100h for Ethernet frames (802.3ac tag format)

Canonical Always set to 0

Defining random early detection
The command
random-detect
is used to request random early detection (RED). When a queue carries lots of
TCP transfers that last longer than simple web requests, there is a risk that TCP flow-control might be inefficient. A burst-tolerance index between 1 and 10 may optionally be specified (exponential filter weight). The
no
form of this command reverts the queue to default “tail-drop” behavior.
Mode: Source
Command Purpose
node(src)[name]#random-detect {burst-tolerance} Defines random early detection (RED) for
queues of for the selected traffic-class or policy
name. The range for the optional value bursttolerance is from 1 to 10.
Discarding Excess Load
police
The command
controls traffic arriving in a queue for class name. The value of the first argument aver-
age-kilobits defines the average permitted rate in kbps, the value of the second argument kilobits-ahead defines
the tolerated burst size in kbps ahead of schedule. Excess packets are dropped.
This procedure describes defining discard excess load

Radio and TV Interference (FCC Part 15)
The OnSite router generates and uses radio frequency energy, and if not installed and used properly-that is, in
strict accordance with the manufacturer’s instructions-may cause interference to radio and television reception.
The OnSite router have been tested and found to comply with the limits for a Class A computing device in
accordance with specifications in Subpart B of Part 15 of FCC rules, which are designed to provide reasonable
protection from such interference in a commercial installation. However, there is no guarantee that interference will not occur in a particular installation. If the OnSite router does cause interference to radio or television
reception, which can be determined by disconnecting the unit, the user is encouraged to try to correct the
interference by one or more of the following measures: moving the computing equipment away from the
receiver, re-orienting the receiving antenna and/or plugging the receiving equipment into a different AC outlet
(such that the computing equipment and receiver are on different branches).
