TCP Status

TCP is a connection-oriented, reliable protocol that is defined at the Transport layer of the OSI reference model. TCP is responsible for breaking messages into segments, reassembling them at the destination station, and resending anything that is not received.

The TCP Status dialog gives complete information on the TCP sessions available on the device. It also gives a detailed description of the TCP counters. The dialog is also updated whenever a new TCP connection is established on the device. The network engineer can view the existing TCP connection and use this information to debug the problems in the network.

The TCP connections can be viewed using the following commands:

•show tcp brief

•show tcp

The Cisco 12000/10720 Router Manager uses the TCP-MIB to populate the TCP Status dialog fields.

The TCP Status section covers the following areas:

•Viewing the TCP Status Window
