Release	Modification
12.0(5)XE2	This command was introduced.
12.1(1)E	This command was integrated into Cisco IOS Release 12.1(1)E.
12.1(5)T	This command was integrated into Cisco IOS Release 12.1(5)T.
12.1(13)E	This command was implemented on Catalyst 6000 family switches without FlexWAN modules.

Usage Guidelines

The show ip nbar port-map command displays port assignments for NBAR protocols.

This command is used to display the current protocol-to-port mappings in use by NBAR. When the ip nbar port-map command has been used, the show ip nbar port-map command displays the ports assigned by the user to the protocol. If no ip nbar port-map command has been used, the show ip nbar port-map command displays the default ports. The protocol-name argument can also be used to limit the display to a specific protocol.

Examples

The following is sample output from the show ip nbar port-map command:

Router# show ip nbar port-map

port-map bgp      udp 179 

port-map bgp      tcp 179 

port-map cuseeme  udp 7648 7649 

port-map cuseeme  tcp 7648 7649 

port-map dhcp     udp 67 68 

port-map dhcp     tcp 67 68

Command	Description
ip nbar-port-map	Configures NBAR to search for a protocol or protocol name using a port number other than the well-known port.

show ip nbar protocol-discovery

To display the statistics gathered by the network-based application recognition (NBAR) Protocol Discovery feature, use the show ip nbar protocol-discovery command in privileged EXEC mode.

show ip nbar protocol-discovery [interface interface-spec] [stats {byte-count | bit-rate  | packet-count}] [{protocol protocol-name | top-n number}]

Syntax Description

interface	(Optional) Specifies that Protocol Discovery statistics for the interface are to be displayed.
interface-spec	(Optional) Specifies an interface to display.
stats	(Optional) Specifies that the byte count, byte rate, or packet count is to be displayed.
byte-count	(Optional) Specifies that the byte count is to be displayed.
bit-rate	(Optional) Specifies that the bit rate is to be displayed.
packet-count	(Optional) Specifies that the packet count is to be displayed.
protocol	(Optional) Specifies that statistics for a specific protocol are to be displayed.

Usage Guidelines

Statistics for all interfaces on which the Protocol Discovery feature is enabled are displayed.

Use the show ip nbar protocol-discovery command to display statistics gathered by the NBAR Protocol Discovery feature. This command, by default, displays statistics for all interfaces on which protocol discovery is currently enabled. The default output of this command includes, in the following order, input bit rate (in bits per second), input byte count, input packet count, and protocol name.

Protocol discovery can be used to monitor both input and output traffic and may be applied with or without a service policy enabled. NBAR protocol discovery gathers statistics for packets switched to output interfaces. These statistics are not necessarily for packets that exited the router on the output interfaces, because packets may have been dropped after switching for various reasons, including policing at the output interface, access lists, or queue drops.

Examples

The following example displays partial output of the show ip nbar protocol-discovery command for an Ethernet interface:

Router# show ip nbar protocol-discovery interface Fastethernet 6/0

RSVP Compression Method Prediction Example

The following example of the show ip rsvp installed detail command shows the compression parameters, including the compression method, the compression context ID, and the bytes saved per packet, on the serial3/0 interface in effect:

Router# show ip rsvp installed detail 

RSVP:Ethernet2/1 has no installed reservations

RSVP:Serial3/0 has the following installed reservations

RSVP Reservation. Destination is 10.1.1.2. Source is 10.1.1.1, 

  Protocol is UDP, Destination port is 18054, Source port is 19156

  Compression:(method rtp, context ID = 1, 37.98 bytes-saved/pkt avg)
