Use this procedure to configure FA message authentication on an interface (port or MLT).
enable
configure terminal
interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...][slot/all][all]} or interface mlt <1-512>
Note
If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
[default] [no] fa message-authentication
Note
When FA is enabled, message authentication is enabled by default. The authentication key is set to the default value and displays encrypted on the output.
Switch:1>en Switch:1#conf t Enter configuration commands, one per line. End with CNTL/Z. Switch:1(config)#
Enable message authentication on a port.
Switch:1(config)#interface gigabitEthernet 1/2 Switch:1(config-if)#fa message-authentication Switch:1(config-if)#show fa interface port 1/2 ================================================================== Fabric Attach Interfaces ================================================================== INTERFACE SERVER MGMT MGMT MSG AUTH MSG AUTH ORIGIN STATUS ISID CVID STATUS KEY ------------------------------------------------------------------ Port1/2 enabled 0 0 enabled **** ------------------------------------------------------------------ 1 out of 1 Total Num of fabric attach interfaces displayed ------------------------------------------------------------------ Switch:1(config-if)#exit Switch:1(config)#
Enable message authentication on an MLT.
Switch:1(config)#interface mlt 10 Switch:1(config-mlt)#fa message-authentication Switch:1(config-mlt)#show fa interface mlt 10 =================================================================== Fabric Attach Interfaces =================================================================== INTERFACE SERVER MGMT MGMT MSG AUTH MSG AUTH ORIGIN STATUS ISID CVID STATUS KEY ------------------------------------------------------------------- Mlt10 enabled 0 0 enabled **** ------------------------------------------------------------------- 1 out of 1 Total Num of fabric attach interfaces displayed ------------------------------------------------------------------- Switch:1(config-mlt)#exit Switch:1(config)#
The following example demonstrates disabling message authentication on a port or MLT.
Switch:1(config)#interface gigabitEthernet 1/2 Switch:1(config-if)#no fa message-authentication Switch:1(config-if)exit Switch:1(config) Switch:1(config)#interface mlt 10 Switch:1(config-mlt)#no fa message-authentication Switch:1(config-mlt)#show fa interface =================================================================== Fabric Attach Interfaces =================================================================== INTERFACE SERVER MGMT MGMT MSG AUTH MSG AUTH ORIGIN STATUS ISID CVID STATUS KEY ------------------------------------------------------------------- Port1/2 enabled 0 0 disabled **** Mlt10 enabled 0 0 disabled **** ------------------------------------------------------------------- 2 out of 2 Total Num of fabric attach interfaces displayed -------------------------------------------------------------------
