Function

The display tunnel-info command displays the tunnel information.

Format

display tunnel-info { tunnel-id tunnel-id | all | statistics [ slots ] }

Parameters

Parameter	Description	Value
tunnel-id tunnel-id	Specifies the tunnel ID. If the specified ID does not exist, the system prompts errors.	The tunnel ID is an integer in hex. It ranges from 1 to 0xFFFFFFFE.
all	Displays the tunnel information about all the tunnels.	-
statistics	Displays statistics about all tunnels.	-
slots	Displays tunnel statistics based on the slots number.	-

Usage Guidelines

Using the display tunnel-info all command, you can:

View the existing tunnel IDs, tunnel types, destination IP address and Token information.

Judge whether a tunnel is set up or not. If a tunnel is not set up successfully, the tunnel ID is 0x0.

The output of the display tunnel-info all command does not contain information about a tunnel whose ID is 0x0.

Using the display tunnel-info tunnel-id command, you can view the detailed information about a tunnel even if you know only the tunnel ID.

Using the display tunnel-info statistics command, you can view how many tunnels are set up on the FW.

Example

# Display the tunnel information.

<sysname> display tunnel-info 1100200a
