Cisco Cisco IOS Software Release 12.2(14)SX

Enter the terminal monitor command in global configuration mode and enter the necessary debug 
condition glbp, debug glbp errors, debug glbp events, debug glbp packets, or debug glbp terse 
commands. Try to enter only specific keywords to isolate the output to a certain subcomponent and 
minimize the load on the processor. To disable logging on the virtual terminal, enter the no terminal 
monitor command.

Enter the specific no form of the command when you are finished.

This procedure will minimize the load on the router created by the debug condition glbp, debug glbp 
errors, debug glbp events, debug glbp packets, or debug glbp terse command because the console 
port is no longer generating character-by-character processor interrupts. If you cannot connect to a 
console directly, you can run this procedure via a terminal server. If you must break the Telnet 
connection, however, you may not be able to reconnect because the router may be unable to respond due 
to the processor load of generating the debugging output.

To monitor and maintain the Gateway Load Balancing Protocol feature, use the following command in 
EXEC mode, as needed.

This section provides the following configuration examples:

In the following example, Router A, shown in Figure 1, is configured with a number of GLBP 
commands:

interface FastEthernet0/0

 ip address 10.21.8.32 255.255.255.0

 glbp 10 authentication text stringxyz

 glbp 10 forwarder preempt delay minimum 60
