Description

Display Compressed Real-Time Transport Protocol (CRTP) extensive output.

Options

none	Display CRTP extensive output for all interfaces.
extensive	(Optional) Display extensive CRTP information.
interface `interface-name`	(Optional) Display CRTP flow statistics for the specified interface. On M Series and T Series routers, a link services IQ (lsq-`fpc`/`pic`/`port`) or redundant link services IQ (rlsq-`fpc`/`pic`/`port`) interface.

Output Fields

Table 1 lists the output fields for the show services crtp command. Output fields are listed in the approximate order in which they appear.

Table 1: show services crtp Output Fields
Field Name	Field Description
Interface	Name of the physical interface.
Port minimum Port maximum	Compression is applied to UDP packets with even ports in the specified range.
Maximum UDP compressed sessions	Maximum value of a context identifier in the space of context identifiers allocated for UDP.
CRTP maximum period	Maximum interval between full headers. Suggested value is 256.
CRTP maximum time	Maximum time interval between full headers. Suggested value is 5 seconds.
Compression ratio	Ratio of received packet size to compressed packet size, in percentage. For example, if the packet size is 100 bytes when it is received, and is 40 bytes after compression, the compression ratio is 100 ? 40/100 * 100 = 60%.
Decompression ratio	Ratio of received packet size to decompressed packet size, in percentage. For example, if the packet size is 40 bytes when it is received, and is 100 bytes after compression, the decompression ratio is 100 ? 40/100 * 100 = 60%.
Discards	Number of frames that the incoming packet match code discarded because they were not recognized.
Sessions	Total number of active CRTP sessions.
IP bytes	Number of IP bytes sent and received.
Compressed bytes	Number of compressed IP header bytes sent and received.
CRTP packets	Number of CRTP packets sent and received.
CUDP/CNTCP packets	Number of compressed UDP packets and compressed non-TCP packets sent and received.
Full header packets	Number of full header packets sent and received. Full header packets communicate the uncompressed IP header plus any following headers and data to establish the uncompressed header state in the decompressor for a particular context.
Context state packet	Number of context state packets sent and received. Context state packets are sent from the decompressor to the compressor to communicate a list of context IDs for which synchronization is lost or might be lost.
IP packets	Number of IP packets sent and received.
Compressed packets	Number of compressed packets sent and received.
