Displays system tunnel information for a specified tunnel or for all tunnels.
tunnel_name | Specifies a tunnel name. |
vr | Specifies showing tunnel information by VR. |
vrname | Specifies showing tunnel information for a specific VR by name. The default is the context VR. |
all | Specifies showing tunnels for all VRs. |
payload-vr | Specifies showing tunnel information for payload VRs. |
payload_vrname | Specifies showing tunnel information for a specific payload VR by name. If not specified, all tunnel payload VRs are shown. |
detail | Shows detailed information for a tunnel. |
If not specified, the VR of current command context is used.
If not specified, all tunnel payload VRs are shown.
The tunnel keyword is optional only when you specify a valid IPv6-in-IPv4 or IPv6-to-IPv4 tunnel name. The Total tunnels count in the display represents all tunnels on the switch.
The following example displays system tunnel information for all tunnels:
# show tunnel Name Type Flags tunfour 6in4 10.20.30.40 => 10.10.10.10 U mytun GRE 1.1.1.2 => 1.1.1.1 Utunfive2 6to4 10.20.30.40 => *.*.*.* D Total tunnels: 3 Flags: (U) Up / (D) Down / (a) Administratively Disabled (S) System Disabled (incompatible hardware)
The following example displays system tunnel information for tunnel "tunfour":
# show "tunfour" Name Type Flags tunfour 6in4 10.20.30.40 => 10.10.10.10 U Total tunnels: 2 Flags: (U) Up / (D) Down
The following example shows detailed information about tunnel "mytunl":
# show tunnel mytun1 detail Tunnel Name : mytun Tunnel Type : GRE Flags : Administratively Disabled Source Address : 1.1.1.1 Destination Address : 1.1.1.2 IPv4 Forwarding : Enabled Virtual Router (VR) : vr-transport Payload VR : vr-tenant Interface Address : 2.0.0.1/24
The following example shows detailed information about tunnel "mytunnel" with TCP MSS adjustment configuration:
# show mytunnel detail Tunnel Name : mytunnel Tunnel Type : GRE Flags : Up Source Address : 1.1.1.1 Destination Address : 1.1.1.2 IPv4 Forwarding : Enabled Virtual Router (VR) : VR-Default Payload VR : VR-Default Interface Address : 2.0.0.1/24 TCP Adjust MSS : On TCP MSS Value : 1360
The following example shows detailed information about tunnel "mytunnel" with an IP MTU value of 1400:
# show mytunnel detail Tunnel Name : mytunnel Tunnel Type : GRE Flags : Up Source Address : 1.1.1.1 Destination Address : 1.1.1.2 IPv4 Forwarding : Enabled Virtual Router (VR) : VR-Default Payload VR : VR-Default Interface Address : 2.0.0.1/24 IP MTU : 1400 TCP Adjust MSS : On TCP MSS Value : 1360
This command was first available in ExtremeXOS 11.2.
Options to specify VR/payload VR and detailed tunnel information were added in ExtremeXOS 31.2.
TCP MSS adjustment information was added in ExtremeXOS 31.6.
This command is available on the platforms listed for the IPv6 interworking feature in the ExtremeXOS 32.7.1 Feature License Requirements document.
