# Monitoring Tunnel-Service Interfaces

You can monitor tunnel-service interfaces by using the show tunnel-server command.

| Note: The E120 and E320 Broadband Services routers output for monitor and show commands is identical to output from other E Series routers, except that the E120 and E320 router output also includes information about the adapter identifier in the interface specifier (slot/adapter/port).

show tunnel-server

- Use to display status and configuration information for dedicated and shared tunnel-server ports and tunnel-service interfaces configured on the router. Unconfigured tunnel-server ports are not displayed in the output.
- You can display information for a specific tunnel-server port or for all tunnel-server ports.
- Use the optional config keyword to display information about available and provisioned tunnel-service interfaces on each port, and to indicate whether modules that support the use of dedicated or shared tunnel-server ports are currently installed in the router.
- Field descriptions
  - Port:Appl—Identifier in slot/port or slot/adapter/port format for the module or tunneling application
    - slot—Number of the slot in the chassis where the module resides
    - adapter—Number of the bay in which the I/O adapter (IOA) resides.

      This identifier applies only to dedicated and shared tunnel-server ports configured on the E120 and E320 routers. Dedicated tunnel-server ports are always adapter 0; shared tunnel-server ports are always adapter 2.

    - port—Number of the tunnel-server port on the module; for dedicated tunnel-server ports, this is a virtual port number that is always 0; for shared tunnel-server ports, this is a virtual port number dynamically assigned by the router
  - Card Type or Active Type—Type of port: dedicated or shared
  - Oper State or Max State—Physical state of the port or application
    - up—Port or application is available
    - down—Port or application is unavailable
    - present—Module associated with this port is installed
    - not present—Module associated with this port has been removed
    - pending—Router has not yet detected all previously configured modules during a reboot or initial installation of the module
  - Active Interfaces or Interfaces—Number of tunnel-service interfaces currently configured on this port
  - Max Interfaces—Total number of tunnel-service interfaces available on this module
  - Fill—Percentage of available interfaces used by a server port, an application on a server port, an application on all server ports, and all server ports
  - Appl Totals—Statistics for each application
  - Server Ports—Displays configuration information about dedicated and shared tunnel-server ports on the router; this display format appears only when the config keyword is specified
    - Port—Identifier in slot/port format (ERX7xx models, ERX14xx models, and ERX310 routers) or slot/adapter/port format (E120 and E320 routers) for the module on which the tunnel-server port resides
    - Type—Type of tunnel-server port: dedicated or shared
    - MaximumInterfaces—Total number of tunnel-service interfaces available on this module
    - Provisioned Interfaces—Total number of tunnel-service interfaces currently provisioned on this port
    - HwPresent—Indicates whether a module that supports the specified tunnel-server port is currently installed in the router: yes or no
- Example 1—Displays information about a dedicated tunnel-server port on an SM
