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.
Examples Supervisor Engine 720 Examples
These examples show the output from Cisco 7600 series routers that are configured with a Supervisor
Engine
720.
This example shows how to display information for all adjacency nodes:
Router# show mls cef adjacency all
Index: 5 smac: 0000.0000.0000, dmac: 0000.0000.0000
mtu: 0, vlan: 0, dindex: 0x0, l3rw_vld: 0
packets: 0, bytes: 0
Release Modification
12.2(14)SX Support for this command was introduced on the Supervisor
Engine
720.
12.2(17d)SXB Support for this command on the Supervisor Engine 2 was extended to
the 12.2
SX release.
12.2(33)SRA This command was integrated into Cisco IOS Release 12.2(33)SRA.
