show mls cef summary
Displays the number of routes in the MLS-hardware Layer 3-switching table for all the protocols.
show mls cef adjacency
To display information about the Multilayer Switching (MLS)-hardware Layer 3-switching adjacency node, use the show mls cef adjacency command in user EXEC or privileged EXEC mode.
show mls cef adjacency [all | decap-tunnel | {encap-tunnel ip-src-addr} | {entry index [to end-range]} | {flags lower-flag upper-flag} | mac-address number | mac-rewrite | macv4 | {mpls [label]} | multicast | nat | recirculation | special | tcp | usage] [detail] [module number]
Syntax Description
Command Modes
User EXEC (>)
Privileged EXEC (#)Command History
Usage Guidelines
The decap-tunnel and endcap-tunnel keywords are used to display the tunnel nodes. The encapsulator node is considered the tunnel-entry point and the decapsulator node is considered the tunnel-exit point. There may be multiple source-destination pairs using the same tunnel between the encapsulator and decapsulator.
The decap-tunnel and endcap-tunnel keywords are not supported on Cisco 7600 series routers that are configured with a Supervisor Engine 720.
The flags keyword applies to all adjacency formats (for example, mac-rewrite, mpls, and multicast) and indicates the bits that are set in the adjacency for the specific adjacency.
The module number keyword and argument designate the module and port number. Valid values depend on the chassis and module used. For example, if you have a 48-port 10/100BASE-T Ethernet module installed in a 13-slot chassis, valid values for the module number are from 1 to 13 and valid values for the port number are from 1 to 48.
MLS-hardware Layer 3 switching applies to IP traffic only.
MLS-hardware Layer 3-switching adjacency statistics are updated every 60 seconds.
You can display hardware-switched IP-directed broadcast information by entering the show mls cef adjacency mac-address number detail command.
For each MLS-hardware Layer 3-switching Forwarding Information Base (FIB) entry, MLS-hardware Layer 3 switching stores Layer 2 information from the MSFC2 for adjacent nodes in the MLS-hardware Layer 3-switching adjacency table. Adjacent nodes are directly connected at Layer 2. To forward traffic, MLS-hardware Layer 3 switching selects a route from a MLS-hardware Layer 3-switching FIB entry, which points to a MLS-hardware Layer 3-switching adjacency entry, and uses the Layer 2 header for the adjacent node in the adjacency table entry to rewrite the packet during Layer 3 switching. MLS-hardware Layer 3 switching supports one million adjacency-table entries.

Usage Guidelines
For Cisco 7600 series routers that are configured with a Supervisor Engine 2, the only supported syntax for the show mls cef ip multicast command is show mls cef ip {multicast tcam [prefix [mask]} [module num]].
There are two Multicast Multilayer Switching (MMLS) modes, ingress and egress. The output displayed differs for each mode.
The hardware-entry types are as follows:
•
•
•
•
•
•
The designated forwarder (DF) index field ranges from 1 to 4 and is an index into the acceptance (Protocol Independent Multicast [PIM] Route Processors (RPs) multiplied by the DF) table. The acceptance table is used with DF forwarding and is used to identify the set of DF interfaces for each of the four RPs in a VPN.

Usage Guidelines
This command is not supported on Cisco 7600 series routers that are configured with a Supervisor Engine 2.
You can enter this command on the supervisor engine and Multilayer Switching (MLS)-hardware Layer 3-switching module consoles only. Enter the remote login command to enter a session into the supervisor engine and distributed forwarding card (DFC)-equipped module to enter the commands.
When entering the ip-address/mask argument, use this format, X:X:X:X::X/mask, where valid values for mask are from 0 to 128.
Up to 64 IPv6 prefixes are supported.
You must enter the L4-src-port and L4-dst-port arguments when the load-sharing mode is set to full, for example, when Layer 4 ports are included in the load-sharing hashing algorithm.

Support for this command on the Supervisor Engine 2 was extended to Release 12.2(17d)SXB.
12.2(33)SRA
This command was integrated into Cisco IOS Release 12.2(33)SRA.
Usage Guidelines
This command is supported on Cisco 7600 series routers that are configured with a Supervisor Engine 2 only.
In Cisco 7600 series routers that are configured with a Supervisor Engine 2 with a PFC and an MSFC2, MLS-hardware Layer 3 switching provides IP unicast and IP multicast Layer 3 switching for a Supervisor Engine 2, a PFC2, an MSFC2, and fabric-enabled switching modules that have a DFC.
The TCAM-inconsistency buffer records any inconsistency that is found in the TCAM.
MLS-hardware Layer 3 switching applies to IP traffic only.
Examples
This example shows how to display the contents of the TCAM inconsistency buffer:

12.2(33)SRA
This command was integrated into Cisco IOS Release 12.2(33)SRA.
Usage Guidelines
This command is not supported on Cisco 7600 series routers that are configured with a Supervisor Engine 2.
The lookup is performed as a "longest-prefix match" and displays the TCAM-entry index that applies to the specified destination IP address.
The information output is in this format: Index, Prefix, Mask, and Adjacency.
The output of the show mls cef lookup ip and the show mls cef lookup commands is identical.
Examples
This example shows how to display the longest prefix match that applies to a specific IPv4-unicast address:

To display event trace messages for Cisco IOS software subsystem components, use the show monitor event-trace command in privileged EXEC mode.

Syntax Description
Command Modes
Privileged EXEC (#)
Command History
Usage Guidelines
Use the show monitor event-trace command to display trace message information.
The trace function is not locked while information is being displayed to the console, which means that new trace messages can accumulate in memory. If entries accumulate faster than they can be displayed, some messages can be lost. If this happens, the show monitor event-trace command will generate a message indicating that some messages might be lost; however, messages will continue to display on the console. If the number of lost messages is excessive, the show monitor event-trace command will stop displaying messages.
Use the bfd keyword for the component argument to display trace messages relating to the BFD feature.
Use the cfd keyword for the component argument to display trace messages relating to the crypto fault detection feature. This keyword displays the contents of the error trace buffers in an encryption data path.
Examples
IPC Component Example
The following is sample output from the show monitor event-trace component command for the interprocess communication (IPC) component.

Usage Guidelines
Use the show monitor event-trace cef command to display trace message information for Cisco Express Forwarding.
The trace function is not locked while information is displayed to the console, which means that new trace messages can accumulate in memory. If entries accumulate faster than they can be displayed, some messages can be lost. If this happens, the show monitor event-trace cef command generates a message indicating that some messages might be lost; however, messages continue to display on the console. If the number of lost messages is excessive, the show monitor event-trace cef command stops displaying messages.

The following is sample output from the show monitor event-trace cef all command:
