What command displays detailed information about the GLBP groups to which the switch belongs?
switch# show standby
switch# show glbp state
switch# show glbp
switch# show standby detail
The command show glbp displays detailed information about GLBP groups on the switch. This information includes the GLBP groups the switch is a member of, whether this is the active switch, the virtual IP address, and whether preemption is enabled. Below is an example of the command output.
The following can be learned from this output:
- This router is the active virtual forwarder (AVF). In line 3, the output indicates the state is listen. This is the state of the active AVF.
- As indicated in line 14, this router is configured with a weighting for tracking of 105. It also is configured with an upper limit of 100 and a lower limit of 90. When a tracked object goes down, the value of 105 will be reduced by the decrement value associated with that object. If this results in the weighting dropping below the lower limit (90), this router will give up its role as AVF.
- The router is tracking two objects, and both have decrement values of 10. This means that ONLY if both objects go down will this router relinquish its role as AVF. As there is another router to take the role of AVF, there will be no disruption of traffic, even if hosts were using the tracked interface that went down.
The show glbp state will only display the glbp state of the router (standby, listen etc). Detailed output is accomplished with the command show glbp.
The command show standby can be used to display detailed information about HSRP groups to which a switch belongs. This command is for HSRP only.
The command show standby detail provides the same output as show standby. It can be used to display detailed information about HSRP groups to which a switch belongs. This command is for HSRP only.
