Use this command to display information related to one or more tunnels.
| ifName | Interface name (for example: tun.0.1). |
| remote-vtep | (Optional) Displays information for the VXLAN Network ID of the tunnel remote end‐point. |
| logical-switch | Logical switch name. |
| vxlan | (Optional) Shows tunnel VXLAN information. |
| logical-switch | (Optional) Shows logical switch information. |
| name | (Optional) Indicates that you are supplying a specific logical switch name. |
| verbose | (Optional) Displays a verbose level of tunnel information, including configuration parameter values and state. |
If no options are specified, a standard level of information related to all tunnel interfaces is displayed.
All command modes.
This 7100-Series example shows how to display information for all tunnels:

Note
Note that the "*" in the keyword display for tun.0.2 ("*888") shows that the configured keyword is "888", and tunneled GRE packets (matching the tunnel source/destination) were received, but dropped, because there was a keyword mismatch. This is displayed in the S- and K-Series verbose display below:System(rw)->show tunnel verbose tun.0.2 Interface: tun.0.2 Mode: gre, State: down ip address 8.0.0.2 255.0.0.0 primary ipv6 address 3020::2/64 Tunnel Source: 2999::1, interface loop.0.1, state up Tunnel Destination: 2888::1, interface vlan.0.50, state up Tunnel Source VRF: global Tunnel Destination VRF: global Encapsulation Limit: no limit, Hop Limit: 64, TOS value: copied from payload Tunnel Keyword 888 Tunnel Admin enabled, Oper down Tunnel Oper Status Down Causes: Tunnel keepalive is down Please check that the tunnel keywords match on each side of the tunnel Keyword mismatch detected.
