Example
To display TCP header compression statistics for all interfaces:
G450-001(super)# show ip tcp header-compression
IP TCP header compression statistics:
Interface Serial 3/1:1.1:
Rcvd:
0 Full Headers, 0 Compressed, 0 Errors
Sent:
85 Full Headers, 34 Compressed,
1139 Bytes Saved, 4335 Bytes Sent,
1.26 Efficiency Improvement Factor
Connect: Active, 3 Rx Slots, 3 Tx Slots
Output fields
Name
Rcvd

Description
Information on received TCP packets, as follows:
Full Headers — the number of TCP packets with full headers
●
received
Compressed — the number of TCP packets with compressed
●
headers received
Errors — the number of packets discarded during
●
de-compression due to errors
Information on sent TCP packets, as follows:
Full Headers — the number of TCP packets with full headers
●
sent
Compressed — the number of TCP packets with compressed
●
headers sent
Bytes Saved — the total saving in bytes due to compression
●
Bytes Sent — the total number of bytes sent after
●
compression
Efficiency Improvement Factor — the improvement factor,
●
calculated as (bytes saved + bytes sent)/ bytes sent (rounded
to two decimal places)
Connection information, as follows:
Active/Inactive — whether TCP header compression is
●
negotiated and working on this interface
Rx Slots — the number of TCP sessions to decompress
●
Tx Slots — the number of TCP sessions to compress
●
