TCP Status

TCP is a connec tion-orien ted, reliabl e prot ocol that is def ined at the T ran sport layer of the OSI reference
model. TCP is responsible for breaking messages into segments, reassembling them at the destination
station , and resend ing anything t hat is not received.
The TCP Stat us di alo g gives complete i nfor matio n on the TCP se ssion s available on the device. I t al so
give s a det aile d descr ipt ion of the TCP c ou nter s. Th e di al og is a lso u pda ted whe never 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 problem s in the networ k.
The TC P connect ions can be viewed using the fo llowing com mands:
•show tcp brief
•show tcp
The Cisc o 12000/107 20 Router Man ager uses the T CP-MIB to pop ulate the TCP St atus dialo g fields.
