To display 802.1X statistics, administrative status, and operational status for the switch or for the specified interface, use the show dot1x command.

Command History
12.1(12c)EW
Support for this command was introduced on the Catalyst 4000 family switch.
Usage Guidelines
If you do not specify an interface, global parameters and a summary are displayed. If you specify an interface, details for that interface are displayed.
If you specify the statistics keyword without the interface interface-id option, statistics are displayed for all interfaces. If you specify the statistics keyword with the interface interface-id option, statistics are displayed for the specified interface.
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output are not displayed, but the lines that contain Output are displayed.

Table 2-12 show dot1x interface Field Description
802.1X is enabled on GigabitEthernet0/2
Status
Status of the port (authorized or unauthorized). The status of a port is displayed as authorized if the dot1x port-control interface configuration command is set to auto and has successfully completed authentication.
Port-control
Setting of the dot1x port-control interface configuration command.
Supplicant
Ethernet MAC address of the client, if one exists. If the switch has not discovered the client, this field displays Not set.
Multiple Hosts
Setting of the dot1x multiple-hosts interface configuration command (allowed or disallowed).
Current Identifier1
Each exchange between the switch and the client includes an identifier, which matches requests with responses. This number is incremented with each exchange and can be reset by the authentication server.
1 This field and the remaining fields in the display show internal state information. For a detailed description of these state machines and their settings, refer to the IEEE 802.1X specification.

12.1(8a)EW
Support for this command was introduced on the Catalyst 4000 family switch.
12.1(12c)EW
Support for extended VLAN addresses was added.
Usage Guidelines
Statistics are collected on a per-VLAN basis for Layer 2-switched packets and Layer 3-switched packets. Statistics are available for both unicast and multicast. The Layer 3-switched packet counts are available for both ingress and egress directions. The per-VLAN statistics are updated every 5 seconds.
In some cases, you might see a difference in the duplex mode displayed between the show interfaces command and the show running-config commands. The duplex mode displayed in the show interfaces command is the actual duplex mode the interface is running. The show interfaces command shows the operating mode for an interface, while the show running-config command shows the configured mode for an interface.
If you do not enter any keywords, all counters for all modules are displayed.

12.1(8a)EW
Support for this command was introduced on the Catalyst 4000 family switch.
Usage Guidelines
The MFIB table contains a set of IP multicast routes; each route in the MFIB table contains several flags that associate to the route.
The route flags indicate how a packet that matches a route is forwarded. For example, the IC flag on an MFIB route indicates that some process on the switch needs to receive a copy of the packet. The following flags are associated with MFIB routes:
•
•
•
A route can also have a set of flags associated with one or more interfaces. For an (S,G) route, the flags on interface 1 indicate how ingress packets should be treated and whether packets matching the route should be forwarded onto interface 1. The following per-interface flags are associated with MFIB routes:
•
•
•
•
For example, the Catalyst 4006 switch with Supervisor Engine III cannot switch tunnel interfaces in hardware so these interfaces are marked with the NP flag. When an NP interface is associated with a route, a copy of every ingress packet arriving on an Accepting interface is sent to the switch software forwarding path for software replication and then forwarded to the NP interface.
Examples
This example shows how to display all active MFIB routes:

show ip mroute
To display IP multicast routing table information, use the show ip mroute command.

Syntax Description

Command Modes

Command History
12.1(8a)EW
Support for this command was introduced on the Catalyst 4000 family switch.
Usage Guidelines
If you omit all optional arguments and keywords, the show ip mroute command displays all entries in the IP multicast routing table.
The show ip mroute active kbps command displays all sources sending at a rate greater than or equal to kbps.
The multicast routing table is populated by creating source, group (S,G) entries from star, group (*,G) entries. The star refers to all source addresses, the "S" refers to a single source address, and the "G" is the destination multicast group address. In creating (S,G) entries, the software uses the best path to that destination group found in the unicast routing table (that is, through Reverse Path Forwarding (RPF).
Examples
This example shows how to display all entries in the IP multicast routing table:
