Privileged EXEC (#)

Command History

Release

Modification

10.0

This command was introduced.

12.2

The output was enhanced to display the number of keepalive, open, update, route-refresh request, and notification messages received and sent by a Border Gateway Protocol (BGP) routing process.

12.2(25)S

The command output was modified.

12.2(28)SB

This command was integrated into Cisco IOS Release 12.2(28)SB and implemented on the Cisco 10000 series routers.

12.2(33)SRA

This command was integrated into Cisco IOS Release 12.2(33)SRA.

12.2(33)SXH

This command was integrated into Cisco IOS Release 12.2(33)SXH.

12.4(20)T

This command was integrated into Cisco IOS Release 12.4(20)T.

12.2(33)SXH5

This command was modified. The output was changed to display the ARP (proxy) reply counter as the number of ARP replies for real proxies only.

Cisco IOS XE Release 3.1S

This command was integrated into Cisco IOS XE Release 3.1S. This command was modified to include the optional interface keyword and associated type and number arguments. These modifications were made to provide support for the IPv4 MIBs as described in RFC 4293: Management Information Base for the Internet Protocol (IP) .

15.1(4)M

This command was modified. The optional interface keyword and associated type and number arguments were added. These modifications were made to provide support for the IPv4 MIBs as described in RFC 4293, Management Information Base for the Internet Protocol (IP) .

Usage Guidelines

Using the show ip trafficcommand with the optional interface keyword displays the ipIfStatsTable counters for the specified interface if IPv4 addressing is enabled.

The table below describes the significant fields shown in the display.

Table 1 show ip traffic Field Descriptions

Field

Description

format errors

Indicates a gross error in the packet format, such as an impossible Internet header length.

bad hop count

Occurs when a packet is discarded because its time-to-live (TTL) field was decremented to zero.

encapsulation failed

Usually indicates that the router had no ARP request entry and therefore did not send a datagram.

no route

Counted when the Cisco IOS software discards a datagram that it did not know how to route.

Command

Description

clear ip traffic

Clears the global or system-wide IP traffic statistics for one or more interfaces.
