show adjacency
To display information about the Cisco Express Forwarding adjacency table or the hardware Layer 3-switching adjacency table, use the show adjacency command in user EXEC or privileged EXEC mode.
show adjacency [ip-address] [interface-type interface-number | null number | port-channel number | sysclock number | vlan number | ipv6-address | fcpa number | serial number] [connectionid number] [link {ipv4 | ipv6 | mpls}] [detail | encapsulation]

Privileged EXEC (#)Command History
Usage Guidelines
The show adjacency command is used to verify that an adjacency exists for a connected device, that the adjacency is valid, and that the MAC header rewrite string is correct.
For line cards, you must specify the line card if_number (interface number). Use the show cef interface command to obtain line card if_numbers.
You can use any combination of the ip-address, interface-type, and other keywords and arguments (in any order) as a filter to display a specific subset of adjacencies.
On Cisco 7600 series routers, hardware Layer 3-switching adjacency statistics are updated every 60 seconds.
Note
On the Cisco 10000 series routers, IPv6 is supported on Cisco IOS Release 12.2(28)SB or later releases.
The following information may be displayed by the show adjacency commands:

show cef
To display information about packets forwarded by Cisco Express Forwarding, use the show cef command in privileged EXEC mode.

Privileged EXEC (#)
Command History
Usage Guidelines
Use this command to display and monitor information about traffic forwarded by Cisco Express Forwarding.
A line card might drop packets because of encapsulation failure, absence of route information, or absence of adjacency information.
A packet is punted (sent to another switch path) because Cisco Express Forwarding may not support a specified encapsulation or feature, the packet may be destined for the router, or the packet may have IP options (such as time stamp and record route). IP options are process switched.

The following example shows how to display Cisco Express Forwarding accounting information:

show cef interface policy-statistics
To display Cisco Express Forwarding (CEF) policy statistical information for a specific interface or for all interfaces, use the show cef interface policy-statistics command in user EXEC or privileged EXEC mode.
show cef interface [type number] policy-statistics [input | output]
Syntax Description
Command Default
By default, this command displays the input statistics only.
Command Modes
User EXEC (>)
Privileged EXEC (#)Command History
Usage Guidelines
This command is available on all software switching platforms, such as the Cisco 7200 series router, and distributed switched platforms, such as the Route Switch Processor (RSP), Gigabit Switch Router (GSR), and the Catalyst 6000 series router.
This command is not supported on Cisco 7600 series routers that are configured with a Supervisor Engine 2.
Two sets of counters are displayed for BGP policy accounting: input counters and output counters. If you enter the show cef interface policy-statistics command without an optional keyword, the command displays only input counters. If you want to display the output counters, you must enter the command with the output keyword. You can also display the input counters by entering the input keyword with the command.
The number of lines in the output of the show cef interface policy-statistics command varies from platform to platform. The software switched platforms support 64 input and 64 output counters and thus 64 lines of output. The Catalyst 6000 family switches and Cisco 7600 series routers support seven input and seven output counters and seven lines of output.
You enable BGP policy accounting on a particular interface when you enter the bgp-policy accounting command in interface configuration mode. To define the conditions for BGP policy accounting, you use the set traffic-index command in route-map configuration mode, the route-map command in global configuration mode, the table-map command in route-map configuration mode, and the match command in route-map configuration mode. The table-map command adds the named route map to the BGP routing table. BGP uses the route map name to set traffic indexes for routes in the IP routing table. The match commands specify the match criteria—the conditions under which policy routing occurs. The set traffic-index command sets the traffic indexes for matching prefixes. The show ip cef detail command displays the traffic index for any particular route.

show interfaces switching
To display the number of packets sent and received on an interface classified by the switching path, use the show interfaces switching command in user EXEC and privileged EXEC mode.
show interfaces [type number] switching
Syntax Description
Command Modes
User EXEC (>)
Privileged EXEC (#)Command History
Usage Guidelines
Use the show interfaces switching command to show which path the router uses and how the traffic is switched. This command is also useful for troubleshooting CPU utilization.
Statistics for packets in, bytes in, packets out, and bytes out are displayed for the available protocols. The statistics are arranged by process, cache misses, fast-path, and autonomous path. All values displayed by the show interfaces switching command are absolute. The clear interface counters command has no effect on these values.
You must enter at least seven characters of the switching keyword (switchi) when you use the show interfaces switching command.
