Syntax: show statistics
The show ip mtu command can be used to see if there is space available for the ip_default_mtu_24
value in the system, or if the MTU value is already configured in the IP table. The following shows an
example output of the show ip mtu command.
Syntax: show ip mtu
Clearing GRE statistics
Use the clear ip tunnel command to clear statistics related to GRE tunnels.
To clear GRE tunnel statistics, enter a command such as the following.
Brocade(config)# clear ip tunnel stat 3
To reset a dynamically-configured MTU on a tunnel Interface back to the configured value, enter a
command such as the following.
Brocade(config)#clear ip tunnel pmtud 3
Syntax: clear ip tunnel [pmtud tunnel-ID | stat tunnel-ID]
Use the pmtud option to reset a dynamically-configured MTU on a tunnel Interface back to the
configured value.
Use the stat option to clear tunnel statistics.
The tunnel-ID variable is a valid tunnel number or name.
Use the clear statistics tunnel [tunnel-ID] command to clear GRE tunnel statistics for a specific
tunnel ID number. To clear GRE tunnel statistics for tunnel ID 3, enter a command such as the
following.
Brocade(config)# clear statistics tunnel 3
Syntax: clear statistics tunnel [tunnel-ID]
The tunnel-ID variable specifies the tunnel ID number.
Brocade(config-tnif-10)#show ip mtu
