Commands To Show Current MTU Value on Cisco 2821

Willie,

There is no single MTU setting for a 2821 router. Each IP-enabled interface can have its own independent MTU. Therefore, you should check each interface separately. The commands:

show interfaces X

show ip interface X

Look for MTU in the output. Replace X with the name and number of the interface you are interested in.

Best regards,

Peter
