Explanation:
The command show standby brief displays the output in the exhibit. It is used to display a summary of the
HSRP groups of which the switch is a member. The summary information it provides includes the group
number, priority, state, active device address, standby address, and group address. In the exhibit, the
interface VLAN 64 is a member of HSRP group 2. Its priority in the group is 100 and it is currently the
standby switch. Since preemption is configured (as indicated by the P following the priority), we know that
the priority of this switch must be lower than the priority of the active device. The active device has an IP
address of 192.168.64.10 and the group IP address is 192.168.64.1.
The command show standby can be used to display detailed information about HSRP groups of which a
switch is a member. It does not provide the quick summary display of the exhibit. This command displays
information about HSRP on all configured interfaces and for all HSRP groups. It also displays hello timer
information and the expiration timer for the standby switch. The command syntax is show standby [type
number [group]].
Below is an example of this command's output:

In the above output, Router A is load-sharing traffic for VLAN 5. It is active for group 1 and standby for
group 2. The router at address 192.168.23.3 is active for group 2 and standby for group 1. This allows
traffic to be sent to both routers while still allowing for redundancy. Router A was also configured with the
standby 1 preempt command (results seen in line 1), which allows it to resume its role as active for group 1
if it comes back up from an outage.
The command show interface vlan is not a complete command. A VLAN number must follow the
command. When provided with a VLAN number, the output would display the status of the SVI, but no
HSRP information.
The command show hsrp is not a valid command due to incorrect syntax.
