This appendix provides a command reference for those Cisco IOS commands—or aspects of the commands—that are unique to Layer 3 switching on the Catalyst 8540 CSR, Catalyst 8510 CSR, and Catalyst 8540 MSR with Layer 3 functionality. This appendix includes the following categories of commands:
Port snooping lets you transparently mirror traffic from one or more source ports to a destination port. The following commands let you set up and monitor snooping.
To set up port-based traffic mirroring, or snooping, use the snoop command. To disable snooping, use the no form of this command.
Syntax Description
source-port Number of the port or ports being monitored. snoop-direction Direction of traffic on the source port or ports that is monitored: receive, transmit, or both.
Snooping is disabled on all interfaces.
Command Modes
Interface configuration
The snooping destination port can be any port in the system, except for the source port or ports, the Ethernet management port on the route processor, or any ports configured for Fast EtherChannel.
The snooping source port can be any port on an interface module.
There can be multiple snooping destination ports operating simultaneously, but only one destination port can be used per snooping session.
Examples
The following example shows how to set up bidirectional port snooping using the snoop interface configuration command. In this example, the destination port is 12/0/15 and the source port is 0/0/1.

Usage Guidelines
When the SDM autolearn feature is enabled, SDM automatically saves mask-length distribution for the routing database. SDM then uses this mask-length distribution as the initial mask-length distribution, which takes effect during the next system reboot.
To configure the size of each protocol region in the SDM, use the sdm size command.
sdm size region-name {num-entries | k-entries num-k-entries}
Syntax Description
region-name Name of the protocol region for which you want to configure the size. num-entries Size expressed as the number of entries, in the range of 32 to 262144. num-k-entries When used with the keyword k-entries, specifies the size in multiples of 1024 entries.
Command Modes
Global configuration
Usage Guidelines
The combined size entered for all the protocol regions should not exceed the total TCAM sizes of 32K, 64K, or 256K. The supported size can be displayed using the show sdm size command. The size of SDM is represented as the number of base entries. Each protocol region entry can occupy one or more TCAM entries. The combined size of all the protocol regions should be calculated in terms of the base entries. Table A-1 lists the number of TCAM entries needed for each protocol region.
| Protocol Region | TCAM Entries |
|---|---|
ipx-bvi-network | 1 |
ip-adjacency | 1 |
ipx-node | 2 |
ip-prefix | 1 |
ipx-network | 1 |
ip-mcast | 2 |
l2-switching | 2 |
udp-flooding | 2 |
access-list | 4 |
Since the ip-prefix region occupies one TCAM entry, the sdm size ip-prefix k-entries 6 command configures 6K TCAM entries in the SDM for the ip-prefix region. Since each ipx-node entry occupies two TCAM entries, the sdm size ipx-node k-entries 3 command configures 6K TCAM entries in the SDM for the ipx-node region.
Related Commands
To display SDM management information for each protocol region in TCAM, use the show sdm internal EXEC command. The information includes SDM status, minimum TCAM size available, and the TCAM size required for the configuration. For each application region, this command also yields information about the logical start and end of the application region in TCAM, lookup type, key size, and statistics about other key operations.
show sdm internal { all-region | ip-adjacency |ip-multicast | ip-prefix | ipx-network |
Syntax Description
all-region Displays SDM management information for all the protocol regions in TCAM. ip-adjacency Displays SDM management information for the ip-adjacency protocol region in TCAM. ip-multicast Displays SDM management information for the ip-multicast protocol region in TCAM. ip-prefix Displays SDM management information for the ip-prefix protocol region in TCAM. ipx-network Displays SDM management information for the ipx-network protocol region in TCAM. ipx-node Displays SDM management information for the ipx-node protocol region in TCAM.

This command displays TCAM entries for an ACL configured on an interface. It interprets the contents of TCAM and displays them in the same format as the Cisco IOS ACL commands, such as the show access-lists command.
 |
Note Because of optimization, there might not be a one-to-one mapping of the output of the show controllers access-list command and the original access list. |
Examples
The following is sample output from the show controllers access-list command:
Router# show controllers fastethernet 3/0/0 access-list in Input ACL entries for Interface FastEthernet3/0/0 Index:6 Label:2 [V:0 M:1][0 IP] deny ip 100.1.3.0 0.0.0.255 any [V:0 M:2][1 IP] permit ip any any [V:0 M:3][2 IPX] permit 1 2.1000.0000.0003 [V:0 M:4][3 IPX] deny 1 2 [V:0 M:5][4 IPX] deny any any
This output corresponds to the following access-list configuration:
Router# show running-config interface fastethernet 3/0/0 Building configuration... Current configuration: ! interface FastEthernet3/0/0 ip address 1.0.0.1 255.0.0.0 ip access-group 100 in no ip directed-broadcast ipx access-group 800 in ipx network 4 end

The epc port-reload command specifies how the system should respond when a port is detected as being stuck. If a port does not respond for a specified duration of time (set with the epc portstuck-wait command) to messages sent by the CPU, the port is declared stuck. If the epc port-reload command is in effect, the stuck port is reset and its microcode is reloaded so that it resumes normal operation. If the no epc port-reload command is in effect, the port is shut down.
Examples
The following example shows how to specify that a port detected as being stuck should be reset and reloaded:
Router(config)# epc port-reload
Related Commands
To specify how long the port-stuck detection mechanism should wait after a port has stopped responding to CPU requests, use the epc portstuck-wait command. To set this value to its default, use the no epc portstuck-wait command.
epc portstuck-wait seconds
Syntax Description
seconds Length of time, from 0 to 1200 seconds, that the port-stuck detection mechanism should wait before declaring a port to be stuck. A value of zero disables the port-stuck detection mechanism entirely.
Defaults
180 seconds
Command Modes
Global configuration
Syntax Description
For a port to be declared stuck, no response to any requests must be received by the CPU for the length of time specified by the epc portstuck-wait command. Once this time has elapsed with no response, the port is declared stuck and the action specified in the epc port-reload command is taken.
Examples
The following example shows how to specify a wait time of four minutes before declaring a port stuck:
Router# epc portstuck-wait 240
