Arguments 0 | 1
Security
Level
3 (config)
Device Type Serial | UART | SPI
Default 0
Description Enables or disables the tunnel port (wl-tunnel-port) assigned to the Serial 1 (UART1) interface, for
communications.
The tunnel port does not require authentication using the CLI command (auth <username>
<password>
) and will automatically establish a data tunnel with the Serial 1 (UART1) interface only if it
is in listen mode.
0 Disables the tunnel port.
1 Enables the tunnel port.
The tunnel can be enabled/disabled without needing a restart.
The Use of the –p1 suffix is optional.

Opening the tunnel port presents a potential security risk. Since no authentication is
needed to establish a data connection, leaving the port enabled may allow
unauthorized access to the host system.
