	Show the statistics of TCP header compression	show ip tcp header-compression
		[ interface-type interface-number ]
	Clear the storage table items of TCP header compression	clear ip tcp header-compression
		[ interface-type interface-number ]
	Show the statistics of RTP header compression	show ip rtp header-compression
		[ interface-type interface-number ]
	Clear the storage table items of RTP header compression	clear ip rtp header-compression
		[ interface-type interface-number ]
	Enable the debugging information of TCP header	debug ip tcp head-compression
	Enable the debugging information of RTP header	debug ip rtp head-compression

1)Show the statistics of TCP header compression. Quidway# show ip tcp header-compression serial 0

TCP/IP header compression statistics: Interface Serial0:

Rcvd: 0 total, 0 compressed, 0 errors

0 dropped, 0 buffer copies, 0 buffer failures Sent: 430 total 429 compressed,

15122 bytes saved, 139318 bytes sent

1.10 efficiency improvement factor

Connect:16 rx slots, 16 tx slots, 1 long searches, 1 misses

99% hit ratio, five minute miss rate 0 misses/5mins, 0 max.

2)Show the statistics of RTP header compression. Quidway# show ip rtp header-compression serial 0

RTP/UDP/IP header compression statistics: Interface Serial0:

Rcvd: 0 total, 0 compressed, 0 errors

0 dropped, 0 buffer copies, 0 buffer failures Sent: 430 total 429 compressed,

15122 bytes saved, 139318 bytes sent

1.10 efficiency improvement factor

Connect: 16 rx slots, 16 tx slots, 1 long searches, 1 misses 99% hit ratio, five minute miss rate 0 misses/5mins, 0 max.

The above information displays such parameters as the number of RTP packet received and transmitted on Sercial0, the number of the compressed RTP packets, the number of the bytes saved and the efficiency improvement factors.
