Usage
Information
You can optionally configure any customized value for the interface-id option. By default, interface name
is sent as the interface-id value.
It can be configured on all types of interfaces. For example, ethernet interface, port-channel, VLAN, and
virtual-network. No two interfaces can have the same interface-id description value.
Hyphen ( - ) is not supported for the customized interface-id configuration.
When Interface-ID is enabled and custom interface description is not configured, the default Interface-ID
description is updated as below
● For physical interface - Interface name ethernet1/1/1.
● For Port-channel - port-channel100.
● For virtual network interface - virtual-network10.
● For vlt port channel - vlt20.
If the interface is part of VLAN, both VLAN and interface-name are used to update the default interface-
id description.
● If VLAN has port channel, then default description is vlan-port_channel. (physical-port will not
be present).
● If VLAN has physical port, then default description is vlan-physicalport.
● If vn has member port, then default description is vn-name only..
IIf custom description is configured, then custom value is used as interface-id description.
NOTE: This command is restricted to the sysadmin and netadmin user roles.
