# Displaying TCP listeners

Use the following procedure to display information on the current TCP listeners on the switch.

## Procedure steps

1. From the navigation tree, double-click IP Routing.

2. In the IP Routing tree, double-click TCP/UDP.

3. In the work area, click the TCP Listeners tab.

## Variable definitions

The following table describes the fields of the TCP Listeners tab.

Field | Description
--- | ---
LocalAddressType | Specifies the IP address type of the local TCP listener.
LocalAddress | Specifies the local IP address of the TCP listener. The switch represents the value of this field in three possible ways, depending on the characteristics of the listening application: For an application willing to accept both IPv4 and IPv6 datagrams, the value of this object is a zero-length octet string, and the value of the corresponding LocalAddressType field is unknown. For an application willing to accept either IPv4 or IPv6 datagrams, the value of this object must be 0.0.0.0 or ::, with the LocalAddressType identifying the supported address type. For an application that is listening for data destined only to a specific IP address, the value of this object is the specific local address, with LocalAddressType identifying the supported address type.
LocalPort | Specifies the local port number for this TCP connection
