Viewing TCP connections information

View information about TCP connections.

Before you begin

Change the VRF instance as required to view TCP connections information on a specific VRF instance. Not all parameters are configurable on non-default VRFs.

About this task

Among other things, the fields on the TCP connections tab provide important information about the health of connections that traverse your switch.

In particular, the state column lets you know the state of each TCP connection. Of these, synSent, synReceived, and established indicate whether or not a channel is established and listen indicates when an end system is waiting for a returning handshake (SYN).

Procedure

In the navigation pane, expand the Configuration > IPv6 folders.
Click TCP/UDP.
Click the TCP Connections tab.
