Initial
Configuration
This chapter instructs you how to configure and manage the IGP-1271 through the
web user interface. With this facility, you can easily access and monitor through any
one port of the switch all the status of the switch, including MIBs status, each port
activity, Spanning tree status, port aggregation status, multicast traffic, VLAN and
priority status, even illegal access record and so on.
The default values of the IGP-1271 are listed in the table below:
After the IGP-1271 has been finished configuration it interface, you can browse it. For
instance, type http://192.168.1.1 in the address row in a browser, it will show the
following screen and ask you inputting username and password in order to login and
access authentication.
The default username is “admin” and password is ”admin”. For the first time to use,
please enter the default username and password, and then click the <Login> button.
The login process now is completed. In this login menu, you have to input the
complete username and password respectively, the IGP-1271 will not give you a
shortcut to username automatically. This looks inconvenient, but safer.
In the IGP-1271, allowed two or more users using administrator’s identity to manage
this switch, which administrator to do the last setting, it will be an available
configuration to effect the system.

information on how to contact this person. The allowed string length is 0 to 128, and the
allowed content is the ASCII characters from 32 to 126.
System name:
An administratively assigned name for this managed node. By convention, this is the node's
fully-qualified domain name. A domain name is a text string drawn from the alphabet
(A-Za-z), digits (0-9), minus sign (-). No space characters are permitted as part of a name.
The first character must be an alpha character. And the first or last character must not be a
minus sign. The allowed string length is 0 to 255.
System Location:
The physical location of this node(e.g., telephone closet, 3rd floor). The allowed string

2-1.2 IP
The IPv4 address for the switch could be obtained via DHCP Server for VLAN 1. To manually
configure an address, you need to change the switch's default settings to values that are
compatible with your network. You may also need to establish a default gateway between the
switch and management stations that exist on another network segment.
Configure the switch-managed IP information on this page
Configure IP basic settings, control IP interfaces and IP routes.
The maximum number of interfaces supported is 8 and the maximum number of routes is 32.
Web Interface
To configure an IP address in the web interface:
1. Click Configuration, System, IP.
2. Click Add Interface then you can create new Interface on the switch.
3. Click Add Route then you can create new Route on the switch
4. Click Apply
Figure2-1.2: The IP configuration

Parameter description:
IP Configuration
Mode:
Configure whether the IP stack should act as a Host or a Router. In Host mode, IP traffic
between interfaces will not be routed. In Router mode traffic is routed between all
interfaces.
DNS Server
This setting controls the DNS name resolution done by the switch.
There are four servers available for configuration, and the index of the server presents the
preference (less index has higher priority) in doing DNS name resolution.
System selects the active DNS server from configuration in turn, if the preferred server does
not respond in five attempts.
The following modes are supported:
From any DHCP interfaces
The first DNS server offered from a DHCPv4 lease to a DHCPv4-enabled interface will
be used..
No DNS server
No DNS server will be used.
Configured IPv4
Explicitly provide the valid IPv4 unicast address of the DNS Server in dotted decimal
notation.
Make sure the configured DNS server could be reachable (e.g. via PING) for activating
DNS service.
From this DHCPv4 interface
Specify from which DHCPv4-enabled interface a provided DNS server should be
preferred.
Configured IPv6
Explicitly provide the valid IPv6 unicast (except linklocal) address of the DNS Server.
Make sure the configured DNS server could be reachable (e.g. via PING6) for activating
DNS service.
From this DHCPv6 interface
Specify from which DHCPv6-enabled interface a provided DNS server should be
preferred.
From any DHCPv6 interfaces
The first DNS server offered from a DHCPv6 lease to a DHCPv6-enabled interface will
be used.
DNS Proxy
When DNS proxy is enabled, system will relay DNS requests to the currently configured DNS
server, and reply as a DNS resolver to the client devices on the network.
Only IPv4 DNS proxy is now supported.
IP Interfaces
Delete
Select this option to delete an existing IP interface.
VLAN
The VLAN associated with the IP interface. Only ports in this VLAN will be able to access the IP
8
interface. This field is only available for input when creating a new interface.
IPv4 DHCP Enabled
Enable the DHCPv4 client by checking this box. If this option is enabled, the system will configure
the IPv4 address and mask of the interface using the DHCPv4 protocol. The DHCPv4 client will
announce the configured System Name as hostname to provide DNS lookup.
IPv4 DHCP Fallback Timeout
The number of seconds for trying to obtain a DHCP lease. After this period expires, a configured
IPv4 address will be used as IPv4 interface address. A value of zero disables the fallback
mechanism, such that DHCP will keep retrying until a valid lease is obtained. Legal values are 0 to
4294967295 seconds.
IPv4 DHCP Current Lease
For DHCP interfaces with an active lease, this column show the current interface address, as
provided by the DHCP server.
IPv4 Address
The IPv4 address of the interface in dotted decimal notation.
If DHCP is enabled, this field configures the fallback address. The field may be left blank if IPv4
operation on the interface is not desired - or no DHCP fallback address is desired.
IPv4 Mask
The IPv4 network mask, in number of bits (prefix length). Valid values are between 0 and 30 bits
for a IPv4 address.
If DHCP is enabled, this field configures the fallback address network mask. The field may be left
blank if IPv4 operation on the interface is not desired - or no DHCP fallback address is desired.
DHCPv6 Enable
Enable the DHCPv6 client by checking this box. If this option is enabled, the system will configure
the IPv6 address of the interface using the DHCPv6 protocol.
DHCPv6 Rapid Commit
Enable the DHCPv6 Rapid-Commit option by checking this box. If this option is enabled, the
DHCPv6 client terminates the waiting process as soon as a Reply message with a Rapid Commit
option is received.
This option is only manageable when DHCPv6 client is enabled.
DHCPv6 Current Lease
For DHCPv6 interface with an active lease, this column shows the interface address provided by
the DHCPv6 server.
IPv6 Address
The IPv6 address of the interface. A IPv6 address is in 128-bit records represented as eight fields
of up to four hexadecimal digits with a colon separating each field (:). For
example,fe80::215:c5ff:fe03:4dc7. The symbol :: is a special syntax that can be used as a shorthand
way of representing multiple 16-bit groups of contiguous zeros; but it can appear only once.
System accepts the valid IPv6 unicast address only, except IPv4-Compatible address and
IPv4-Mapped address.
The field may be left blank if IPv6 operation on the interface is not desired.
IPv6 Mask
The IPv6 network mask, in number of bits (prefix length). Valid values are between 1 and 128 bits
for a IPv6 address.
The field may be left blank if IPv6 operation on the interface is not desired.
Resolving IPv6 DAD
The link-local address is formed from an interface identifier based on the hardware address which
9
is supposed to be uniquely assigned. Once the DAD (Duplicate Address Detection) detects the
address duplication, the operation on the interface SHOULD be disabled.
At this moment, manual intervention is required to resolve the address duplication. For example,
check whether the loop occurs in the VLAN or there is indeed other device occupying the same
hardware address as the device in the VLAN.
After making sure the specific link-local address is unique on the IPv6 link in use, delete and then
add the specific IPv6 interface to restart the IPv6 operations on this interface.
IP Routes
Delete
Select this option to delete an existing IP route.
Network
The destination IP network or host address of this route. Valid format is dotted decimal
notationor a valid IPv6 notation. A default route can use the value 0.0.0.0or IPv6 :: notation.
Mask Length
The destination IP network or host mask, in number of bits (prefix length). It defines how
much of a network address that must match, in order to qualify for this route. Valid values
are between 0 and 32 bits respectively 128 for IPv6 routes. Only a default route will have a
mask length of 0 (as it will match anything).
Gateway
The IP address of the IP gateway. Valid format is dotted decimal notationor a valid IPv6
notation. Gateway and Network must be of the same type.
Next Hop VLAN (Only for IPv6)
The VLAN ID (VID) of the specific IPv6 interface associated with the gateway.
The given VID ranges from 1 to 4095 and will be effective only when the corresponding IPv6
interface is valid.
If the IPv6 gateway address is link-local, it must specify the next hop VLAN for the gateway.
If the IPv6 gateway address is not link-local, system ignores the next hop VLAN for the
gateway.

2-1.3 NTP
NTP is Network Time Protocol and is used to sync the network time based Greenwich Mean
Time (GMT). If use the NTP mode and select a built-in NTP time server or manually specify an
user-defined NTP server as well as Time Zone, the switch will sync the time in a short after
pressing <Apply> button. Though it synchronizes the time automatically, NTP does not update
the time periodically without user’s processing.
Click to undo any changes made locally and revert to previously saved values.

2-2 Green Ethernet
2-2.1 Port Power Savings
This page allows the user to configure the port power savings features.
EEE is a power saving option that reduces the power usage when there is low or no traffic
utilization.
EEE works by powering down circuits when there is no traffic. When a port gets data to be
transmitted all circuits are powered up. The time it takes to power up the circuits is named
wakeup time. The default wakeup time is 17 us for 1Gbit links and 30 us for other link speeds.
EEE devices must agree upon the value of the wakeup time in order to make sure that both the
receiving and transmitting device has all circuits powered up when traffic is transmitted. The
devices can exchange wakeup time information using the LLDP protocol.
EEE works for ports in auto-negotiation mode, where the port is negotiated to either 1G or 100
Mbit full duplex mode.
For ports that are not EEE-capable the corresponding EEE checkboxes are grayed out and thus
impossible to enable EEE for.
When a port is powered down for saving power, outgoing traffic is stored in a buffer until the
port is powered up again. Because there are some overhead in turning the port down and up,
more power can be saved if the traffic can be buffered up until a large burst of traffic can be
transmitted. Buffering traffic will give some latency in the traffic.
Web Interface
To configure a Port Power Saving Configuration in the web interface:
1. Click Configuration, Green Ethernet and Port Power Savings
2. Evoke to enable or disable the ActiPHY, PerfectReach, EEE and EEE Urgent Queues.
3. Click Apply.
Figure 2-2.1: The Port Power Saving Configuration
Parameter description:
19
Optimize EEE for
The switch can be set to optimize EEE for either best power saving or least traffic latency.
Port:
The switch port number of the logical port.
ActiPHY :
Link down power savings enabled.
ActiPHY works by lowering the power for a port when there is no link. The port is power up
for short moment in order to determine if cable is inserted.
PerfectReach :
Cable length power savings enabled.
PerfectReach works by determining the cable length and lowering the power for ports with
short cables.
EEE :
Controls whether EEE is enabled for this switch port.
For maximizing power savings, the circuit isn't started at once transmit data is ready for a
port, but is instead queued until a burst of data is ready to be transmitted. This will give
some traffic latency.
If desired it is possible to minimize the latency for specific frames, by mapping the frames to
a specific queue (done with QOS), and then mark the queue as an urgent queue. When an
urgent queue gets data to be transmitted, the circuits will be powered up at once and the
latency will be reduced to the wakeup time.
EEE Urgent Queues
Queues set will activate transmission of frames as soon as data is available. Otherwise the
Squeue will postpone transmission until a burst of frames can be transmitted.

Link :
The current link state is displayed graphically. Green indicates the link is up and red
that it is down.
Current Link Speed :
Provides the current link speed of the port.
Configured Link Speed :
Selects any available link speed for the given switch port. Only speeds supported by
the specific port is shown. Possible speeds are:
Disabled - Disables the switch port operation.
Auto - Port auto negotiating speed with the link partner and selects the highest
speed that is compatible with the link partner.
10Mbps HDX - Forces the cu port in 10Mbps half-duplex mode.
10Mbps FDX - Forces the cu port in 10Mbps full duplex mode.
100Mbps HDX - Forces the cu port in 100Mbps half-duplex mode.
100Mbps FDX - Forces the cu port in 100Mbps full duplex mode.
1Gbps FDX - Forces the port in 1Gbps full duplex
2.5Gbps FDX - Forces the Serdes port in 2.5Gbps full duplex mode.
SFP_Auto_AMS - Automatically determines the speed of the SFP. Note: There is no
standardized way to do SFP auto detect, so here it is done by reading the SFP rom.
Due to the missing standardized way of doing SFP auto detect some SFPs might not
be detectable. The port is set in AMS mode. Cu port is set in Auto mode.
100-FX - SFP port in 100-FX speed. Cu port disabled.
1000-X - SFP port in 1000-X speed. Cu port disabled.
Ports in AMS mode with 1000-X speed has Cu port preferred.
Ports in AMS mode with 1000-X speed has fiber port preferred.
Ports in AMS mode with 100-FX speed has fiber port preferred.
22
Advertise Duplex
When duplex is set as auto i.e auto negotiation, the port will only advertise the
specified duplex as either Fdx or Hdx to the link partner. By default port will
advertise all the supported duplexes if the Duplex is Auto.
Advertise Speed
When Speed is set as auto i.e auto negotiation, the port will only advertise the
specified speeds (10M100M 1G) to the link partner. By default port will advertise all
the supported speeds if speed is set as Auto.
Flow Control :
When Auto Speed is selected on a port, this section indicates the flow control capability
that is advertised to the link partner.
When a fixed-speed setting is selected, that is what is used. The Current Rx column
indicates whether pause frames on the port are obeyed, and the Current Tx column
indicates whether pause frames on the port are transmitted. The Rx and Tx settings are
determined by the result of the last Auto Negotiation.
Check the configured column to use flow control. This setting is related to the setting for
Configured Link Speed.
NOTICE: The 100FX standard doesn't support Auto Negotiation, so when in 100FX mode
the flow control capabilities will always be shown as "disabled".Maximum Frame Size :
Enter the maximum frame size allowed for the switch port, including FCS.
PFC
When PFC (802.1Qbb Priority Flow Control) is enabled on a port then flow control
on a priority level is enabled. Through the Priority field, range (one or more) of
priorities can be configured, e.g. '0-3,7' which equals '0,1,2,3,7'. PFC is not
supported through auto negotiation. PFC and Flowcontrol cannot both be enabled
on the same port.
Maximum Frame Size
Enter the maximum frame size allowed for the switch port, including FCS. The
rangeis 1518-9600 bytes.
Excessive Collision Mode :
Configure port transmit collision behavior.
23
Discard: Discard frame after 16 collisions (default).
Restart: Restart backoff algorithm after 16 collisions.
Frame Length Check
Configures if frames with incorrect frame length in the EtherType/Length field shall
be dropped. An Ethernet frame contains a field EtherType which can be used to
indicate the frame payload size (in bytes) for values of 1535 and below. If the
EtherType/Length field is above 1535, it indicates that the field is used as an
EtherType (indicating which protocol is encapsulated in the payload of the frame). If
"frame length check" is enabled, frames with payload size less than 1536 bytes are
dropped, if the EtherType/Length field doesn't match the actually payload length. If
"frame length check" is disabled, frames are not dropped due to frame length
mismatch. Note: No drop counters count frames dropped due to frame length
mismatch

local : use the local user database on the switch for authentication.
radius : use a remote RADIUS server for authentication.
tacacs+ : use a remote TACACS+ server for authentication.
Methods that involves remote servers are timed out if the remote servers are offline.
In this case the next method is tried. Each method is tried from left to right and
continues until a method either approves or rejects a user. If a remote server is used
for primary authentication it is recommended to configure secondary
authentication as 'local'. This will enable the management client to login via the
local user database if none of the configured authentication servers are alive.

2-5.1.7 SNMP
Any Network Management System (NMS) running the Simple Network Management
Protocol (SNMP) can manage the Managed devices equipped with SNMP agent,
provided that the Management Information Base (MIB) is installed correctly on the
managed devices. The SNMP is a protocol that is used to govern the transfer of
information between SNMP manager and agent and traverses the Object Identity (OID)
of the management Information Base (MIB), described in the form of SMI syntax.
SNMP agent is running on the switch to response the request issued by SNMP
manager.
Basically, it is passive except issuing the trap information. The switch supports a switch
to turn on or off the SNMP agent. If you set the field SNMP “Enable”, SNMP agent will
be started up. All supported MIB OIDs, including RMON MIB, can be accessed via
SNMP manager. If the field SNMP is set “Disable”, SNMP agent will be de-activated,
the related Community Name, Trap Host IP Address, Trap and all MIB counters will be
ignored.
2-5.1.7.1 System
This section describes how to configure SNMP System on the switch. This function is
used to configure SNMP settings, community name, trap host and public traps as well
as the throttle of SNMP. A SNMP manager must pass the authentication by
identifying both community names, then it can access the MIB information of the
target device. So, both parties must have the same community name. Once
completing the setting, click <Apply> button, the setting takes effect.
Web Interface

2-5.2.1 Limit Control
This section shows you to configure the Port Security settings of the Switch. You can
use the Port Security feature to restrict input to an interface by limiting and identifying
MAC addresses.
Web Interface
To configure a Configuration of Limit Control in the web interface:
1. Select “Enabled” in the Mode of System Configuration.
2. Checked Aging Enabled.
3. Set Aging Period (Default is 3600 seconds).
To configure a Port Configuration of Limit Control in the web interface:

68
2. Specify the maximum number of MAC addresses in the Limit of Port Configuration.
3. Set Action (Trap, Shutdown, Trap & Shutdown)
4. Click Apply.
Figure 2-5.2.1: The Port Security Limit Control Configuration
Parameter description:
System Configuration
Mode :
Indicates if Limit Control is globally enabled or disabled on the switch. If globally
disabled, other modules may still use the underlying functionality, but limit checks
and corresponding actions are disabled.
Aging Enabled :
If checked, secured MAC addresses are subject to aging as discussed under Aging
69
Period.
Aging Period :
If Aging Enabled is checked, then the aging period is controlled with this input. If
other modules are using the underlying port security for securing MAC addresses,
they may have other requirements to the aging period. The underlying port security
will use the shorter requested aging period of all modules that use the functionality.
The Aging Period can be set to a number between 10 and 10,000,000 seconds.
To understand why aging may be desired, consider the following scenario: Suppose
an end-host is connected to a 3rd party switch or hub, which in turn is connected to
a port on this switch on which Limit Control is enabled. The end-host will be
allowed to forward if the limit is not exceeded. Now suppose that the end-host logs
off or powers down. If it wasn't for aging, the end-host would still take up resources
on this switch and will be allowed to forward. To overcome this situation, enable
aging. With aging enabled, a timer is started once the end-host gets secured. When
the timer expires, the switch starts looking for frames from the end-host, and if such
frames are not seen within the next Aging Period, the end-host is assumed to be
disconnected, and the corresponding resources are freed on the switch.
Port Configuration
The table has one row for each port on the selected switch and a number of
columns, which are:
Port :
The port number to which the configuration below applies.
Mode :
Controls whether Limit Control is enabled on this port. Both this and the Global
Mode must be set to Enabled for Limit Control to be in effect. Notice that other
modules may still use the underlying port security features without enabling Limit
Control on a given port.
Action :
If Limit is reached, the switch can take one of the following actions:
None: Do not allow more than Limit MAC addresses on the port, but take no
further action.
Trap: If Limit + 1 MAC addresses is seen on the port, send an SNMP trap. If Aging is
70
disabled, only one SNMP trap will be sent, but with Aging enabled, new SNMP traps
NOTE: That clicking the reopen button causes the page to be
refreshed, so non-committed changes will be lost
will be sent every time the limit gets exceeded.
Shutdown: If Limit + 1 MAC addresses is seen on the port, shut down the port. This
implies that all secured MAC addresses will be removed from the port, and no new
address will be learned. Even if the link is physically disconnected and reconnected
on the port (by disconnecting the cable), the port will remain shut down. There are
three ways to re-open the port:
Trap & Shutdown: If Limit + 1 MAC addresses is seen on the port, both the "Trap"
and the "Shutdown" actions described above will be taken.
State :
1) Boot the switch,
2) Disable and re-enable Limit Control on the port or the switch,
3) Click the Reopen button.
This column shows the current state of the port as seen from the Limit Control's
point of view. The state takes one of four values:
Disabled: Limit Control is either globally disabled or disabled on the port.
Ready: The limit is not yet reached. This can be shown for all actions.
Limit Reached: Indicates that the limit is reached on this port. This state can only
be shown if Action is set to none or Trap.
Shutdown: Indicates that the port is shut down by the Limit Control module. This
state can only be shown if Action is set to shut down or Trap & Shutdown.
Re-open Button :
If a port is shut down by this module, you may reopen it by clicking this button,
which will only be enabled if this is the case. For other methods, refer to shut down
in the Action section.

Figure 2-5.2.2: The Network Access Server Configuration
72
Parameter description:
Mode :
Indicates if NAS is globally enabled or disabled on the switch. If globally disabled, all
ports are allowed forwarding of frames.
Reauthentication Enabled :
If checked, successfully authenticated supplicants/clients are reauthenticated after
the interval specified by the Reauthentication Period. Reauthentication for
802.1X-enabled ports can be used to detect if a new device is plugged into a switch
port or if a supplicant is no longer attached.
For MAC-based ports, reauthentication is only useful if the RADIUS server
configuration has changed. It does not involve communication between the switch
and the client, and therefore doesn't imply that a client is still present on a port (see
Aging Period below).
73
Reauthentication Period :
Determines the period, in seconds, after which a connected client must be
reauthenticated. This is only active if the Reauthentication Enabled checkbox is
checked. Valid values are in the range 1 to 3600 seconds.
EAPOL Timeout :
Determines the time for retransmission of Request Identity EAPOL frames.
Valid values are in the range 1 to 255 seconds. This has no effect for MAC-based
ports.
Aging Period :
This setting applies to the following modes, i.e. modes using the Port Security
functionality to secure MAC addresses:
• Single 802.1X
• Multi 802.1X
• MAC-Based Auth.
When the NAS module uses the Port Security module to secure MAC addresses, the
Port Security module needs to check for activity on the MAC address in question at
regular intervals and free resources if no activity is seen within a given period of
time. This parameter controls exactly this period and can be set to a number
between 10 and 1000000 seconds.
If reauthentication is enabled and the port is in an 802.1X-based mode, this is not
so critical, since supplicants that are no longer attached to the port will get removed
upon the next re-authentication, which will fail. But if re-authentication is not
enabled, the only way to free resources is by aging the entries.
For ports in MAC-based Auth. mode, reauthentication doesn't cause direct
communication between the switch and the client, so this will not detect whether
the client is still attached or not, and the only way to free any resources is to age the
entry.
Hold Time :
This setting applies to the following modes, i.e. modes using the Port Security
functionality to secure MAC addresses:
• Single 802.1X
74
• Multi 802.1X
• MAC-Based Auth.
If a client is denied access - either because the RADIUS server denies the client
access or because the RADIUS server request times out (according to the timeout
specified on the "Configuration→Security→AAA" page) - the client is put on hold in
the Un-authorized state. The hold timer does not count during an on-going
authentication.
In MAC-based Auth. mode, the switch will ignore new frames coming from the
client during the hold time.
The Hold Time can be set to a number between 10 and 1000000 seconds.
Port Configuration :
The table has one row for each port on the selected switch and a number of
columns, which are:
Port :
The port number for which the configuration below applies.
Admin State :
If NAS is globally enabled, this selection controls the port's authentication mode.
The following modes are available:
Force Authorized :
In this mode, the switch will send one EAPOL Success frame when the port link
comes up, and any client on the port will be allowed network access without
authentication.
Force Unauthorized :
In this mode, the switch will send one EAPOL Failure frame when the port link
comes up, and any client on the port will be disallowed network access.
Port-based 802.1X :
In the 802.1X-world, the user is called the supplicant, the switch is the authenticator,
and the RADIUS server is the authentication server. The authenticator acts as the
man-in-the-middle, forwarding requests and responses between the supplicant and
the authentication server. Frames sent between the supplicant and the switch are
75
special 802.1X frames, known as EAPOL (EAP Over LANs) frames. EAPOL frames
NOTE: Suppose two backend servers are enabled and that the
server timeout is configured to X seconds (using the AAA
configuration page), and suppose that the first server in the list
is currently down (but not considered dead).
Now, if the supplicant retransmits EAPOL Start frames at a rate
faster than X seconds, then it will never get authenticated,
because the switch will cancel on-going backend authentication
server requests whenever it receives a new EAPOL Start frame
from the supplicant.
And since the server hasn't yet failed (because the X seconds
haven't expired), the same server will be contacted upon the
next backend authentication server request from the switch. This
scenario will loop forever. Therefore, the server timeout should
be smaller than the supplicant's EAPOL Start frame
retransmission rate.
encapsulate EAP PDUs (RFC3748). Frames sent between the switch and the RADIUS
server are RADIUS packets. RADIUS packets also encapsulate EAP PDUs together
with other attributes like the switch's IP address, name, and the supplicant's port
number on the switch. EAP is very flexible, in that it allows for different
authentication methods, like MD5-Challenge, PEAP, and TLS. The important thing is
that the authenticator (the switch) doesn't need to know which authentication
method the supplicant and the authentication server are using, or how many
information exchange frames are needed for a particular method. The switch simply
encapsulates the EAP part of the frame into the relevant type (EAPOL or RADIUS)
and forwards it.
When authentication is complete, the RADIUS server sends a special packet
containing a success or failure indication. Besides forwarding this decision to the
supplicant, the switch uses it to open up or block traffic on the switch port
connected to the supplicant
Single 802.1X :
76
In port-based 802.1X authentication, once a supplicant is successfully authenticated
on a port, the whole port is opened for network traffic. This allows other clients
connected to the port (for instance through a hub) to piggy-back on the
successfully authenticated client and get network access even though they really
aren't authenticated. To overcome this security breach, use the Single 802.1X variant.
Single 802.1X is really not an IEEE standard, but features many of the same
characteristics as does port-based 802.1X. In Single 802.1X, at most one supplicant
can get authenticated on the port at a time. Normal EAPOL frames are used in the
communication between the supplicant and the switch. If more than one supplicant
is connected to a port, the one that comes first when the port's link comes up will
be the first one considered. If that supplicant doesn't provide valid credentials
within a certain amount of time, another supplicant will get a chance. Once a
supplicant is successfully authenticated, only that supplicant will be allowed access.
This is the most secure of all the supported modes. In this mode, the Port Security
module is used to secure a supplicant's MAC address once successfully
authenticated.
Multi 802.1X :
In port-based 802.1X authentication, once a supplicant is successfully authenticated
on a port, the whole port is opened for network traffic. This allows other clients
connected to the port (for instance through a hub) to piggy-back on the
successfully authenticated client and get network access even though they really
aren't authenticated. To overcome this security breach, use the Multi 802.1X variant.
Multi 802.1X is really not an IEEE standard, but features many of the same
characteristics as does port-based 802.1X. Multi 802.1X is - like Single 802.1X - not
an IEEE standard, but a variant that features many of the same characteristics. In
Multi 802.1X, one or more supplicants can get authenticated on the same port at
the same time. Each supplicant is authenticated individually and secured in the MAC
table using the Port Security module.
In Multi 802.1X it is not possible to use the multicast BPDU MAC address as
destination MAC address for EAPOL frames sent from the switch towards the
supplicant, since that would cause all supplicants attached to the port to reply to
requests sent from the switch. Instead, the switch uses the supplicant's MAC address,
which is obtained from the first EAPOL Start or EAPOL Response Identity frame sent
by the supplicant. An exception to this is when no supplicants are attached. In this
case, the switch sends EAPOL Request Identity frames using the BPDU multicast
MAC address as destination - to wake up any supplicants that might be on the port.
77
The maximum number of supplicants that can be attached to a port can be limited
using the Port Security Limit Control functionality.
MAC-based Auth.:
Unlike port-based 802.1X, MAC-based authentication is not a standard, but merely
a best-practices method adopted by the industry. In MAC-based authentication,
users are called clients, and the switch acts as the supplicant on behalf of clients.
The initial frame (any kind of frame) sent by a client is snooped by the switch, which
in turn uses the client's MAC address as both username and password in the
subsequent EAP exchange with the RADIUS server. The 6-byte MAC address is
converted to a string on the following form "xx-xx-xx-xx-xx-xx", that is, a dash (-) is
used as separator between the lower-cased hexadecimal digits. The switch only
supports the MD5-Challenge authentication method, so the RADIUS server must be
configured accordingly.
When authentication is complete, the RADIUS server sends a success or failure
indication, which in turn causes the switch to open up or block traffic for that
particular client, using the Port Security module. Only then will frames from the
client be forwarded on the switch. There are no EAPOL frames involved in this
authentication, and therefore, MAC-based Authentication has nothing to do with
the 802.1X standard.
The advantage of MAC-based authentication over port-based 802.1X is that several
clients can be connected to the same port (e.g. through a 3rd party switch or a hub)
and still require individual authentication, and that the clients don't need special
supplicant software to authenticate. The advantage of MAC-based authentication
over 802.1X-based authentication is that the clients don't need special supplicant
software to authenticate. The disadvantage is that MAC addresses can be spoofed
by malicious users - equipment whose MAC address is a valid RADIUS user can be
used by anyone. Also, only the MD5-Challenge method is supported. The maximum
number of clients that can be attached to a port can be limited using the Port
Security Limit Control functionality.
RADIUS-Assigned QoS Enabled :
When RADIUS-Assigned QoS is both globally enabled and enabled (checked) on a
given port, the switch reacts to QoS Class information carried in the RADIUS
Access-Accept packet transmitted by the RADIUS server when a supplicant is
successfully authenticated. If present and valid, traffic received on the supplicant's
port will be classified to the given QoS Class. If (re-)authentication fails or the
78
RADIUS Access-Accept packet no longer carries a QoS Class or it's invalid, or the
supplicant is otherwise no longer present on the port, the port's QoS Class is
immediately reverted to the original QoS Class (which may be changed by the
administrator in the meanwhile without affecting the RADIUS-assigned).
This option is only available for single-client modes, i.e.
• Port-based 802.1X
• Single 802.1X
RADIUS attributes used in identifying a QoS Class:
Refer to the written documentation for a description of the RADIUS attributes
needed in order to successfully identify a QoS Class. The User-Priority-Table
attribute defined in RFC4675 forms the basis for identifying the QoS Class in an
Access-Accept packet.
Only the first occurrence of the attribute in the packet will be considered, and to be
valid, it must follow this rule:
• All 8 octets in the attribute's value must be identical and consist of ASCII
characters in the range '0' - '3', which translates into the desired QoS Class in the
range [0; 3].
RADIUS-Assigned VLAN Enabled :
When RADIUS-Assigned VLAN is both globally enabled and enabled (checked) for a
given port, the switch reacts to VLAN ID information carried in the RADIUS
Access-Accept packet transmitted by the RADIUS server when a supplicant is
successfully authenticated. If present and valid, the port's Port VLAN ID will be
changed to this VLAN ID, the port will be set to be a member of that VLAN ID, and
the port will be forced into VLAN unaware mode. Once assigned, all traffic arriving
on the port will be classified and switched on the RADIUS-assigned VLAN ID.
If (re-)authentication fails or the RADIUS Access-Accept packet no longer carries a
VLAN ID or it's invalid, or the supplicant is otherwise no longer present on the port,
the port's VLAN ID is immediately reverted to the original VLAN ID (which may be
changed by the administrator in the meanwhile without affecting the
RADIUS-assigned).
This option is only available for single-client modes, i.e.
• Port-based 802.1X
79
• Single 802.1X
For trouble-shooting VLAN assignments, use the "Monitor→VLANs→VLAN
Membership and VLAN Port" pages. These pages show which modules have
(temporarily) overridden the current Port VLAN configuration.
RADIUS attributes used in identifying a VLAN ID:
RFC2868 and RFC3580 form the basis for the attributes used in identifying a VLAN
ID in an Access-Accept packet. The following criteria are used:
• The Tunnel-Medium-Type, Tunnel-Type, and Tunnel-Private-Group-ID attributes
must all be present at least once in the Access-Accept packet.
• The switch looks for the first set of these attributes that have the same Tag value
and fulfil the following requirements (if Tag == 0 is used, the
Tunnel-Private-Group-ID does not need to include a Tag):
- Value of Tunnel-Medium-Type must be set to "IEEE-802" (ordinal 6).
- Value of Tunnel-Type must be set to "VLAN" (ordinal 13).
- Value of Tunnel-Private-Group-ID must be a string of ASCII chars in the range '0'
- '9', which is interpreted as a decimal string representing the VLAN ID. Leading '0's
are discarded. The final value must be in the range [1; 4095].
Guest VLAN Enabled :
When Guest VLAN is both globally enabled and enabled (checked) for a given port,
the switch considers moving the port into the Guest VLAN according to the rules
outlined below.
This option is only available for EAPOL-based modes, i.e.:
• Port-based 802.1X
• Single 802.1X
• Multi 802.1X
For trouble-shooting VLAN assignments, use the "Monitor→VLANs→VLAN
Membership and VLAN Port" pages. These pages show which modules have
(temporarily) overridden the current Port VLAN configuration.
Guest VLAN Operation:
When a Guest VLAN enabled port's link comes up, the switch starts transmitting
80
EAPOL Request Identity frames. If the number of transmissions of such frames
exceeds Max. Reauth. Count and no EAPOL frames have been received in the
meanwhile, the switch considers entering the Guest VLAN. The interval between
transmissions of EAPOL Request Identity frames is configured with EAPOL Timeout.
If Allow Guest VLAN if EAPOL Seen is enabled, the port will now be placed in the
Guest VLAN. If disabled, the switch will first check its history to see if an EAPOL
frame has previously been received on the port (this history is cleared if the port
link goes down or the port's Admin State is changed), and if not, the port will be
placed in the Guest VLAN. Otherwise it will not move to the Guest VLAN, but
continue transmitting EAPOL Request Identity frames at the rate given by EAPOL
Timeout.
Once in the Guest VLAN, the port is considered authenticated, and all attached
clients on the port are allowed access on this VLAN. The switch will not transmit an
EAPOL Success frame when entering the Guest VLAN.
While in the Guest VLAN, the switch monitors the link for EAPOL frames, and if one
such frame is received, the switch immediately takes the port out of the Guest VLAN
and starts authenticating the supplicant according to the port mode. If an EAPOL
frame is received, the port will never be able to go back into the Guest VLAN if the
"Allow Guest VLAN if EAPOL Seen" is disabled.
Port State :
The current state of the port. It can undertake one of the following values:
Globally Disabled: NAS is globally disabled.
Link Down: NAS is globally enabled, but there is no link on the port.
Authorized: The port is in Force Authorized or a single-supplicant mode and the
supplicant is authorized.
Unauthorized: The port is in Force Unauthorized or a single-supplicant mode and
the supplicant is not successfully authorized by the RADIUS server.
X Auth/Y Unauth: The port is in a multi-supplicant mode. Currently X clients are
authorized and Y are unauthorized.
Restart :
Two buttons are available for each row. The buttons are only enabled when
authentication is globally enabled and the port's Admin State is in an EAPOL-based
or MAC-based mode.
81
Clicking these buttons will not cause settings changed on the page to take effect.
Re-authenticate: Schedules a re-authentication whenever the quiet-period of the
port runs out (EAPOL-based authentication). For MAC-based authentication,
re-authentication will be attempted immediately.
The button only has effect for successfully authenticated clients on the port and will
not cause the clients to get temporarily unauthorized.
Reinitialize: Forces a re-initialization of the clients on the port and thereby a
re-authentication immediately. The clients will transfer to the unauthorized state
while the re-authentication is in progress.

2-5.2.3 ACL
The IGP-1271 Series switch access control list (ACL) is probably the most commonly
used object in the IOS. It is used for packet filtering but also for selecting types of
traffic to be analyzed, forwarded, or influenced in some way. The ACLs are divided into
Ether Types. IPv4, ARP protocol, MAC and VLAN parameters etc. Here we will just go
over the standard and extended access lists for TCP/IP. As you create ACEs for ingress
classification, you can assign a policy for each port, the policy number is 1-8, and
however, each policy can be applied to any port. This makes it very easy to determine
what type of ACL policy you will be working with.

2-5.2.3.3 Access Control List
The section describes how to configure Access Control List rule. An Access Control List
(ACL) is a sequential list of permit or deny conditions that apply to IP addresses, MAC
addresses, or other more specific criteria. This switch tests ingress packets against the
conditions in an ACL one by one. A packet will be accepted as soon as it matches a
permit rule, or dropped as soon as it matches a deny rule. If no rules match, the frame
is accepted. Other actions can also be invoked when a matching packet is found,
including rate limiting, copying matching packets to another port or to the system log,
or shutting down a port.
This page shows the Access Control List (ACL), which is made up of the ACEs defined
on this switch. Each row describes the ACE that is defined. The maximum number of
ACEs is 256 on each switch. Click on the lowest plus sign to add a new ACE to the list.
