traffic-segmentation forward
This command is used to restrict the Layer 2 packet forwarding domain of packets received by the configured
port. Use the
no
form of this command to remove the specification of forwarding domain.

[, | -]
no traffic-segmentation forward interface

Parameters
interface
INTERFACE-ID
Specifies the ID of an interface allowed. The allowed interfaces
include physical port.
,
(Optional) Specifies a series of interfaces, or separate a range of
interfaces from a previous range. No space before and after the
comma.
-
(Optional) Specifies a range of interfaces. No space before and
after the hyphen.
Default
None.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 15.
Usage Guideline
When traffic segmentation forwarding domain is specified, packets received by the port will be restricted in
Layer 2 packet forwarding to interfaces within the domain. When the forwarding domain of a port is empty,
Layer 2 forwarding for packets received by the port is not restricted.
The traffic-segmentation forward command can be entered multiple times. The following interfaces will be
appended into the forwarding domain. Use the no form command will remove the specified interface from the
traffic segmentation forward member list.
The traffic segmentation member list can be comprised of different interface types, for example port and port-
channel in the same forwarding domain. If the interfaces specified by the command include a port-channel, all
the member ports of this port-channel will be included in the forwarding domain.
If the forwarding domain of an interface is empty, then there is no restriction on Layer 2 forwarding of packets
received by the port.
Example
This example shows how to configure traffic segmentation. It restricts the flooding domain of eth1/0/1 to a set
of ports, which are eth1/0/2 – eth1/0/6.
Switch# configure terminal
Switch(config)# interface Ethernet 1/0/1
Switch(config-if)# traffic-segmentation forward interface range eth1/0/2-6
Switch(config-if)#
