that port. Since the above configuration consists of a statically configured active port, the active port
pre-empts other ports in the protected link group. Refer to
Syntax: [no] protected-link-group group-ID ethernet port to port
The group-ID parameter specifies the protected link group number. Enter a number from 1 - 32.
Syntax: [no] protected-link-group group-ID active-port ethernet port
The group-ID parameter specifies the protected link group number. Enter a number from 1 - 32.
Viewing information about protected link groups
You can use the following show commands to view information about protected link groups:
• show protected-link-group
• show interface brief
• show interface
The following shows example output for the show protected-link-group command.
device#show protected-link-group
Group ID: 1
Member Port(s): ethe 1 to 7
Configured Active Port: 7
Current Active Port: 7
Standby Port(s): ethe 5
Total Number of Protected Link Groups: 1
Syntax: show protected-link-group [ group-ID ]
CLI display of protected link group information
TABLE 26
Field
Description
Group ID
The ID number of the protected link group.
Member Port(s)
The ports that are members of the protected link group.
Configured Active Port The statically configured active port. If you do not statically configure an active port, this
value will be "None".
Current Active Port
The current active port for the protected link group. If all member ports are down, this
value will be "None".
Standby Port(s)
The member ports that are on standby.
The show interface brief command also displays information about protected link groups.
device#show int brief e 3 to 4
Port Link State Dupl Speed Trunk Tag Priori MAC Name
3 Up Inactive Full Auto None Yes level0 0000.00a8.7140
4 Up Forward Full 1G None Yes level0 0000.00a8.7140
In the above output, the State of port 3 is Inactive , which means port 3 is an inactive port in a
protected link group. For active ports in a protected link group, the State will be Active.
Syntax: show interface brief ethernet port
The show interface command also displays information about protected link groups.
device#show int e 3
