A Look at
CoreWatch
Cabletron Systems’ CoreWatch is a comprehensive, easy-to-use, device management and
configuration application for SmartSwitch Routers (SSRs). Based on Java Programming
Language, CoreWatch provides configuration, monitoring, and reporting capabilities with
the assistance of wizards, property sheets, and drag-and-drop operations.
CoreWatch provides access to Configuration Expert, a utility that makes tasks such as
configuring routers, virtual local area networks (VLANs), application-level Quality of
Service (QoS) policies, and security filters simple and easy.
You can run CoreWatch in the Solaris, Windows NT, or Windows 95 environments.
This chapter
•Summarizes the features of CoreWatch
•Describes the system requirements of CoreWatch
•Provides an overview of CoreWatch capabilities
•Discusses the different modes of CoreWatch
•Provides a list of the Management Information Bases (MIBs) CoreWatch supports
What Are CoreWatchs Features?
CoreWatch management features include the following:
•Java-based graphical user interface (GUI).
•Simplified bridging configuration.
CoreWatchUsersGuide19
Page 20
Chapter1:ALookatCoreWatch
•Simplified routing configuration.
•Quality of Service (QoS) policy management.
QoS is a set of parameters that assign priorities to different types of traffic, define flows
for Internet Protocol (IP) and Internetwork Packet Exchange (IPX) packet fields, assign
a precedence to the fields of the flows you define, and establish queuing policies.
•Configuration of security filters and access control lists (ACLs). An ACL is a list the
SSR keeps to control access to or from various services.
•Drag-and-drop VLAN setup and administration.
•Detailed reporting in the hypertext markup language (HTML) format.
System Requirements
CoreWatch can run in the Solaris, Windows NT, and Windows 95 environments. As
shown in the following table, CoreWatch’s system requirements depend upon your
operating system. The table identifies which browser to use with each operating system
and gives the minimum hardware requirements for each environment.

–Check the status of each bridge table, routing table, and QoS table. These tables
contain information that CoreWatch obtains from MIBs it supports. (For a list of
these MIBS, see “Which MIBs Does the SSR Support?” on page 21.)
–Display messages stored in the SSR boot log.
–SNMP is a protocol that provides support for monitoring and controlling network
devices, collecting statistics, and managing configurations, performance, and
security. SNMP is mainly used by Transmission Control Protocol/Internet Protocol
(TCP/IP) networks. (TCP/IP is a suite of protocols that provide a relatively simple
way to connect computers and devices from different vendors on a worldwide
internetwork.)
CoreWatch displays most monitoring information in tables and reports, but there is some
data that is displayed in the form of graphs or dials.
A Look at the Modes of CoreWatch
CoreWatch can run in the following modes:
Chapter1:ALookatCoreWatch
•User, which is the mode CoreWatch automatically begins operating in after you log in
to CoreWatch. Use this mode to monitor the activity on the SSR or to obtain reports.
•Configure, which is the mode you use to perform any of the following tasks:
–Change system information
–Configure bridging and VLANs
–Set QoS policies
–Set security filters
•Configure multiple configuration databases as discussed later in this guide
You switch to the configure mode by starting Configuration Expert. Access to
Configuration Expert is controlled by a password that your system administrator can set
as discussed in “Changing the Privileged Password” on page 32.

The contents of the right pane changes depending on what task you are performing in
Configuration Expert. Initially the right pane contains the legend that describes some of
the Configuration Expert icons. As you configure the SSR, the right pane will contain the
wizard or dialog box necessary for the configuration task you are performing.
The Configuration Expert Toolbar at the top of the window is used to perform some
Configuration Expert tasks as discussed in “A Look at the Configuration Tree Icons” on
page 42.
Configuration Tree
The configuration tree is a graphical representation of the SSR’s configuration. The
configuration tree includes the configuration files discussed in “Configuration Files” on
page 41. When you are configuring the SSR, you can use the configuration tree to view the
contents of the configuration files so you can add, edit, or delete objects in those files.
Chapter4:LearningConfigurationExpertBasics
You can view the contents of a configuration file by double-clicking its name or icon in the
configuration tree. When you do so, Configuration Expert displays the file’s subtree. As
shown in the following figure, a configuration file’s subtree includes system, bridging,
routing, QoS, and security configuration objects. There are separate subtrees for each
configuration file.
Double-clicking a
configuration file
displays that file’s
subtree
Figure8.ConfigurationTree
You navigate a subtree by double-clicking its objects or clicking the plus sign (+) of
objects. As you do so, Configuration Expert expands the subtree to display the object’s
contents. In the following figure, the System Configuration subtree has been expanded to

display the contents of the Chassis Configuration object and the Module-1 object. As the
figure shows, a plus sign (+) indicates an object can be expanded further and a minus sign
(-) indicates an object cannot be expanded. You can close an expanded object by doubleclicking it or clicking its minus sign (-).
While configuring the SSR, you can continue double-clicking subtree objects until you are
able to select the object you want to add, edit, or delete. After you select a configurable
object, the wizard or dialog box used to configure that object appears in the right pane of
the Configuration Expert window.

Configuration Expert stores SSR configuration information in the following configuration
files:
•Active Configuration—a file containing the configuration settings for the current SSR
session.
•Startup Configuration—a file containing the configuration settings used whenever the
SSR is started.
•Custom Configuration—a file in which you can save the settings of an Active
Configuration file. Custom Configuration files let you:
–Save changes when you have not finished making changes to an Active
–Quickly change the SSR’s configuration for different environments. Suppose you

are configuring the SSR to establish traffic priority for an accounting department.
You could create one Custom Configuration file for the handling of traffic at the
end-of-a-month, and create another Custom Configuration file for handling traffic
at the end of the fiscal year. You would then be able to quickly switch traffic
priority by configuring the SSR with the desired Custom Configuration file.
You can save configuration settings by committing those changes to a configuration file as
discussed in “Committing Your Configuration Changes” on page 46.
Configuration Expert includes a CLI editor that you can open by selecting the Configure
menu and choosing Open Config CLI Editor. Use this editor to type CLI commands into
a configuration file. The following figure summarizes the CLI Editor toolbar, which is
located at the top of the CLI Editor window:

Configuring Ports
Configuration Expert lets you enable and disable ports as well as configure the following
characteristics:
•Operating mode (half-duplex or full-duplex).
In half-duplex mode, a port can transmit data in only one direction at a time between
two stations.
In full-duplex mode, a port can simultaneously send and receive data.
•Port speed (10-Mbps or 100-Mbps). This parameter applies only to ports on the
10/100 modules.
•Auto negotiation (for Gigabit Ethernet ports)
Figure13.SystemIDDialogBox
•Hash mode, which controls the distribution of flow entries in Layer-2 and Layer-3
lookup tables. (For more information on hash modes, see “Configuring Global Settings
on All Ports” on page 51.)
50CoreWatchUsersGuide
Page 51
Chapter5:ChangingSystemSettings
Note:
You can configure global settings for all SSR ports as well as configure individual ports. If
most of an SSR’s ports are to be configured with the same or similar settings, you can first
apply global settings to all ports and then modify those settings on individual ports as
needed. Separate discussions on configuring default settings for all ports and configuring
an individual port follow.
Cabletron has configured the SSR’s hash mode to its optimal setting. It is
recommended you not change the hash mode unless advised to do so by
Cabletron Technical Support.
Configuring Global Settings on All Ports
To configure global settings on all of the SSR’s ports:
1.Start Configuration Expert if you have not already done so.
2.Open the configuration file you want to modify and then double-click that file’s
System Configuration object.
3.Double-click the Chassis Configuration object.
4.Click the Global Port Parameters object.

Chapter5:ChangingSystemSettings
Negotiate Port Speed and Mode check box. Otherwise, clear the check box to disable auto
negotiation on all Gigabit Ethernet ports.
All Gigabit Ethernet ports use auto negotiation. If auto negotiation is not set on a
Gigabit Ethernet port, that port uses the full-duplex mode and operates at 1000 Mbps.
6.If you want to configure 10/100 Mbps Ethernet ports, do one of the following.
Otherwise, skip to step step 7.
–If you want all 10/100 Mbps Ethernet ports to detect and then use the operating
mode or speed of the network segment to which the port is connected, select the
appropriate Autodetect options.
–If you want to set all 10/100 Mbps Ethernet ports’ operating mode or speed to a
specific setting, select the appropriate buttons.
All 10/100 Mbps Ethernet ports use autodetection by default.
The 100 FX ports do not use auto-detection. They always use full-duplex mode and
operate at 100 Mbps.
Note:
7.Set the Layer 2 hash mode for all ports. The hash mode controls the distribution of
flow entries in Layer-2 and Layer-3 lookup tables. Assuming a MAC address of the
value 0011:2233:4455, the following list describes the various hash modes.
–M0 – 0011:2233:4455
–M1 – 0011:2233:5544
–M2 – 0011:3322:4455 (default hash mode)
–M3 – 1100:2233:4455
Note:
8.Click OK.
If you select an operating mode or speed, the setting disables autodetection
for that parameter on the port. For example, if you set the speed of a segment
to 10 Mbps, that segment no longer uses autodetection for the port speed and
will always attempt to operate at 10 Mbps.
Cabletron has configured the SSR’s hash mode to its optimal setting. It is
recommended you not change the hash mode unless advised to do so by

Configuring the SSR for SNMP
The Simple Network Management Protocol (SNMP) provides support for monitoring and
controlling network devices, collecting statistics, and managing configurations,
performance, and security. SNMP is mainly used by TCP/IP networks.
Chapter5:ChangingSystemSettings
You configure the SSR for SNMP by performing the following tasks:
•Setting up targets for SNMP traps. A target is a management station to which the SSR
sends SNMP traps, which are messages that describe an event (such as restarting the
SSR or a link going down).
•Establishing community strings that SNMP management stations must supply to
access the SSR.
Separate discussions on these SNMP tasks follow.
Setting Up a Target for SNMP Traps
Set up a target for SNMP traps to specify to which server you want the SSR to send SNMP
traps. To set up an SNMP trap target on the SSR:
1.Make sure there is a network connection to the server to which you want the SSR to
send SNMP traps. You can do so by sending a ping packet to the desired server.
2.Start Configuration Expert if you have not already done so.
3.Open the configuration file you want to modify and then double-click that file’s
System Configuration object.

Configuring SSR
Bridging
The SSR provides bridging functions. This chapter
•provides an overview of bridging on an SSR.
•discusses configuring the bridging mode of ports. A port’s bridging mode determines
the contents of that port’s Layer-2 lookup table.
•discusses controlling the aging state of SSR bridging. The SSR’s aging state determines
how long the SSR stores the MAC address information.
•explains setting up the SSR for the Spanning Tree Protocol (STP), which the SSR uses
to work around loops.
A Look at Bridging on the SSR
The SSR uses transparent bridging to link together different segments of an Ethernet
network.
In transparent bridging, the SSR operates as a learning bridge. As such, it monitors traffic
on subnetworks to learn about destination locations, down bridges, traffic congestion, and
other network information. This frees packets from having to carry routing information
and permits the SSR to forward packets based on current network conditions.
As a learning bridge, the SSR stores the source MAC address of each packet it receives.
This permits the SSR to forward future packets destined for a MAC address to be
forwarded to the port on which the source address was found. It does not forward those
packets to other ports, and thus reduces traffic on the network. If the SSR does not
recognize a packet’s MAC address, however, it forwards that packet to every port.
CoreWatchUsersGuide63

Configuring the Bridging Mode of Ports
You can configure ports to use either of the following bridging modes. Each port has a
Layer-2 lookup table where MAC address or flows are stored. A port’s bridging mode
determines the contents of each Layer-2 table entry. A port can use only one type of
bridging at a time.
•Flow-based bridging
If a port is configured for flow-based bridging, each Layer-2 table entry contains
entries consisting of a source MAC address, destination MAC address, and VLAN ID.
•Address-based bridging
If a port is configured for address-based bridging (the default), each Layer-2 table entry
contains a unique destination MAC address and VLAN ID.
Suppose that a port on the SSR is connected to a hub that is connected to three
workstations, A, B, and C. If each workstation is talking to one another and sending
broadcast traffic, the Layer-2 table on the SSR’s port would contain the following entries
for the workstations (assume that the VLAN ID is 1 for all entries):

Controlling the Aging State of SSR Bridging
The SSR ages learned MAC addresses in the Layer-2 lookup tables. Each port has its own
Layer-2 lookup table. When a learned MAC address entry ages out, the SSR removes that
entry from a port’s Layer-2 lookup tables unless you disable aging on that port.
You can control the aging of learned MAC address entries in the SSR’s Layer-2 lookup
tables. To do so, use Configuration Expert to perform the following tasks:
•Setting up an aging timeout that ports use by default. The SSR uses the aging timeout
to determine how long to keep learned MAC addresses. Aging is a regulation
mechanism the SSR uses to clean up MAC address entries that have not been used for
awhile.
•Overriding the default timeout interval. You do so by setting timeout intervals on any
ports that are to use an interval different from the default aging timeout.
•Disabling aging on a port if you do not want the SSR to remove MAC address entries
from that port’s Layer-2 lookup table.
Separate discussions on each task follow.
Setting Up a Default Aging Timeout
You can set an aging time for learned MAC address entries that all ports use by default.
When the aging time expires for a MAC address, the SSR removes the MAC address from
the port that uses the default timeout. To set up a default aging timeout for MAC address
entries:
1.Start Configuration Expert if you have not already done so.
2.Open the configuration file you want to modify and then double-click that file’s
Bridging Configuration object.
3.Double-click the Aging Configuration object.
4.In the list of aging objects that appears, select the Default Aging Timeout object.

Overriding the Default Timeout Interval on a Port
As discussed in “Setting Up a Default Aging Timeout” on page 68, you can set an aging
timeout for learned MAC address entries that ports use by default. You may override this
default timeout if you want a port to use a different timeout interval. To override the
timeout interval on a port:

Setting Up STP on the SSR
The SSR uses the Spanning Tree Protocol (STP) to dynamically discover a loop-free
topology.
STP includes an algorithm that permits bridges to send Bridge Protocol Data Units
(BPDUs). Unless a bridge is a root bridge, it uses the information in a BPDU to perform
the following operations. (A root bridge is a bridge that uses STP to prevent loops by
periodically exchanging topology information with other bridges.)
1.Select a root bridge.
2.Calculate the shortest path from itself to the root bridge.
3.Select a designated bridge.
A designated bridge is the bridge responsible for forwarding frames to a LAN
segment.
4.Select a root port.
A root port is a port that provides the best path from the bridge to the root bridge.
5.Select which ports are included in a spanning tree.
On the SSR, you can enable STP per port. This approach offers flexibility. STP BPDUs that
arrive on ports on which STP is disabled are forwarded only to ports which are part of the
receiving port's VLAN.
You can set up STP on the SSR by performing the following tasks:
Note:
•Defining STP settings for an SSR bridge.
•Defining STP settings for individual ports.
STP is disabled on the SSR by default. If you want the SSR to use STP, you will
need to define the different settings and enable STP.
•Enabling and disabling STP on individual ports.
Separate discussions on these STP tasks follow.

An STP Global Settings dialog box similar to the following appears:
Chapter6:ConfiguringSSRBridging
5.In the Bridging Priority box, enter the STP bridging priority for the SSR.
The bridging priority determines which bridge functions as the root bridge. You can
specify a number from 0 to 65535. The bridge assigned the lowest value is the root
bridge. The default is 32768.
6.In the Hello-time box, enter the number of seconds that you want to elapse between
the BPDUs STP sends.
Specify a number from 1to 10. The default is 2.
7.In the Msg Max Age box, enter the number of seconds you want to specify for the
SSR’s maximum age.
CoreWatchUsersGuide75
Figure28.STPGlobalSettingsDialogBox

receives. You can specify a number from 6 to 40. The default is 20.
8.In the Forward Delay box, enter the number of seconds you want to elapse between
the transitions of the different STP states.
Specify a number from 4 to 30. The default is 15.
9.Click OK.
The SSR bridge will use the specified STP settings. However, individual ports also have
STP settings that you can configure as discussed in “Defining STP Attributes on an
Individual Port” on page 76.
Defining STP Attributes on an Individual Port
In addition to the global STP settings discussed in “Defining STP Settings for SSR
Bridging” on page 75, the SSR uses the following STP attributes that are set on individual
ports.
•Port priority
The STP algorithm uses the port priority to determine which port to use if a bridge has
two ports connected in a loop.
•Port cost
This attribute specifies how much a port contributes to the total cost of the path to the
root bridge when the port is the root.
A port uses the default settings for these attributes. You may, however, change these
default settings on individual ports. To change a port’s priority or cost:
1.Start Configuration Expert if you have not already done so.
2.Open the configuration file you want to modify and then double-click that file’s
Bridging Configuration object.
3.Double-click the Spanning Tree Protocol object.

Configuring VLANs
on the SSR
You configure VLANs to limit the scope of traffic on the SSR. This chapter
•provides an overview of VLANs on the SSR.
•lists tips that make VLAN configuration easy.
•discusses defining ports for VLANs.
•discusses creating the different VLANs the SSR supports.
•describes copying ports to add them to a VLAN.
•discusses modifying VLANs.
A Look at VLANs on the SSR
VLANs contain Layer-2 broadcast and multicast traffic. No traffic is allowed to cross
VLAN boundaries unless it passes through routers. Once connected by routers, VLANs
are equivalent to subnets.
VLANs are created by grouping a set of bridged ports together as part of one bridged
network. Broadcasts from one of the ports in a VLAN are received by other ports in the
group but not by any ports outside of the group. Similarly, unicast traffic is bridged only
between ports in a group but not to ports outside of the group. Thus, traffic is not allowed
to cross the group boundary. A bridge may have multiple VLANs defined thus appearing
as multiple virtual bridges on the SSR.
The SSR supports the following types of VLANs. The VLAN type determines the type of
traffic the SSR will forward on the VLAN.
CoreWatchUsersGuide81
Page 82
Chapter7:ConfiguringVLANsontheSSR
•Protocol-based VLAN, which divides the physical network into logical VLANs based
on one or more of the following protocols:
–IP VLAN, which is a VLAN used for IP traffic.
–IPX VLAN, which is a VLAN used for IPX traffic.
–Bridged-protocol VLAN, which is a VLAN used for bridged protocols (such as
AppleTalk).
•Port-based VLAN, which is a VLAN that is independent of the traffic type. Port-based
VLANs treat IP, IPX, and bridged protocols alike.
The ports in a VLAN can be configured as one of the following:
•Access ports
Access ports can belong to only one VLAN per protocol (IP, IPX, or a bridged protocol).
This is the default for all ports.
On access ports, traffic is sent out without 802.1Q frame format.
•Trunk ports
Trunk ports can belong to any number of VLANs. Use trunk ports when you want to
connect SSR routers together and send traffic for multiple VLANs on a single network
segment connecting the routers.
On trunk ports, traffic is always sent out with 802.1Q frame format.
VLAN Configuration Tips
The following list includes tips that you should keep in mind while configuring VLANs
on an SSR as discussed later in this chapter:
•You can quickly add ports to a VLAN, by copying ports as discussed in “Dragging
Ports to Add Them to a VLAN” on page 97.
•When defining trunk ports, you can define all the ports on a module as trunk ports at
one time rather than defining them individually. To do so, click rather than doubleclick the module in the Access Port list box of the dialog box you use to define ports.
Then click the Add button.
•When defining access ports in a dialog box, you can define all the ports on a module as
access ports at one time rather than defining them individually. To do so, click rather
than double-click the module in the Trunk Port list box of the dialog box you use to
define ports. Then click the Remove button.
•When adding ports to a VLAN, you can add all of a module’s available ports at one
time rather than adding them individually. To do so, click rather than double-click the
module in the Available Port List box of the dialog box you use to add ports. Then click
the Add button.
82CoreWatchUsersGuide
Page 83
Chapter7:ConfiguringVLANsontheSSR
•When removing ports from a VLAN, you can remove all of a module’s ports at one
time rather than removing them individually.To do so, click rather than double-clock
the module in the Selected Port List box of the dialog box you use to add ports. Then
click the Remove button.
Defining Access Ports and Trunk Ports
You can define ports as either access or trunk ports.
All ports are configured as access ports by default. Therefore, you need to define a port as
an access port only if you previously defined it as a trunk port and now want to use it as
an access port, instead. Access ports can be added to only one VLAN.
Define a port as a trunk port if you want to include that port in multiple VLANs. Trunk
ports are useful for connecting SSRs together and for sending traffic of multiple VLANs
on a single network segment connecting the routers. Suppose you have two
VLANs/subnetworks of IP users on separate SSRs and those VLANs need to belong to
the same layer broadcast domain. You could trunk two SSRs together as shown in the
following figure:

1.Start Configuration Expert if you have not already done so.
Note:
2.Open the configuration file you want to modify and then double-click that file’s
Bridging Configuration object.
3.Click the Port Bridging Mode object.

You can also replace a VLAN by copying it to the interface as discussed in “Copying and
Pasting an Object” on page 44.
You can drag only IP VLANs to IP interfaces, and you can drag only IPX
VLANs to IPX interfaces.
Changing Which Ports a VLAN Includes
Configuration Expert lets you change the ports of a VLAN. You can add ports by dragging
them to the VLAN. You can also add and remove ports using a dialog box. Separate
discussions on each operation follow.
Dragging Ports to Add Them to a VLAN
You can quickly add ports to a VLAN by copying those ports from a port list located
elsewhere in the configuration tree. To do so, take the following steps:
