To display information about an GRE tunnel interface, use the run show l3-interface tunnel command in L2/L3 configuration mode.

NOTE:

GRE tunnel is a logical interface created by Linux kernel on software side. Once created, GRE tunnel stays in "UP" state in the display of this show command. Unless it is shut down by CLI command "set l3-interface tunnel ddd disable", the state will change to “DOWN”.

Command Syntax

run show l3-interface tunnel <tunnel-interface-name>

Parameters

Parameter	Description
tunnel <tunnel-interface-name>	The GRE tunnel interface name.
