Syntax: show ip interface tunnel [ tunnel-ID ]
The tunnel-ID variable is a valid tunnel number between 1 and 72.
The show interface tunnel command displays the GRE tunnel conguration and the pmtd aging timer information.

Field Denition
Hardware is Tunnel The interface is a tunnel interface.
Tunnel source The source address for the tunnel.
Tunnel destination The destination address for the tunnel.
Tunnel mode The tunnel mode. The gre species that the tunnel will use GRE
encapsulation (IP protocol 47).
Port name The port name (if applicable).
Internet address The internet address.
MTU The congured path maximum transmission unit.
encapsulation GRE GRE encapsulation is enabled on the port.
Keepalive Indicates whether or not GRE link keepalive is enabled.
Path MTU Discovery Indicates whether or not PMTUD is enabled. If PMTUD is enabled, the
MTU value is also displayed.
Path MTU The PMTU that is dynamically learned.
Age-timer Indicates the pmtd aging timer conguration in minutes.The default is 10.
The range is from 10 - 30.
Path MTU will expire Indicates the time after which the learned PMTU expires. This line is
displayed only when a PMTU is dynamically learned.
The show ip tunnel trac command displays the link status of the tunnel and the number of keepalive packets received and sent on the
tunnel.
