For example, if you specify a Gigabit Ethernet interface and have a 48-port 10/100BASE-T Ethernet module that is 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.
The port-channel number values from 257 to 282 are supported on the CSM and the FWSM only.
The #hosts behind the VLAN is displayed only if you define the max-hosts policy on the specified VLAN and enable the log policy for the specified VLAN.

Usage Guidelines
This command displays which groups are being forwarded and received over the UDL.
On the upstream router, this command shows which interface is a UDL interface and which IP multicast groups are being forwarded out that interface. The UDL Reporter is the IP address of the downstream interface on the receiving router. If there is more than one downstream router, this field shows which downstream router forwarded the IGMP host report to the upstream router over the ground-based network. This report is forwarded over the UDL so that all downstream routers know which groups have already been requested by other downstream routers, and additional IGMP host reports are suppressed.
On the downstream router, this command (in the Interface field) shows which local interface received an IGMP host report (from a connected host for a specific group). The UDL Reporter is the IP address of the router that had forwarded the IGMP host report to the upstream router over the ground-based network. The UDL Interfaces column shows the interface on which IP multicast packets are being received.

This example shows the output of the show ip igmp udlr command on an upstream router:

Usage Guidelines
The Cisco IOS software automatically enters a directly connected route in the routing table if the interface is usable. A usable interface is one through which the software can send and receive packets. If the software determines that an interface is not usable, it removes the directly connected routing entry from the routing table. Removing the entry allows the software to use dynamic routing protocols to determine backup routes to the network, if any.
If the interface can provide two-way communication, the line protocol is marked "up." If the interface hardware is usable, the interface is marked "up."
If you specify an optional interface type, you see only information on that specific interface.
If you specify no optional arguments, you see information on all the interfaces.
When an asynchronous interface is encapsulated with PPP or Serial Line Internet Protocol (SLIP), IP fast switching is enabled. The show ip interface command on an asynchronous interface that is encapsulated with PPP or SLIP displays a message indicating that IP fast switching is enabled.

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 interface-number argument designates the module and port number. Valid values for interface-number depend on the specified interface type and the chassis and module that are used. For example, if you specify a Gigabit Ethernet interface and have a 48-port 10/100BASE-T Ethernet module that is 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.
The port-channel number values are from 257 to 282 are supported on the CSM and the FWSM only.
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 that is found in the unicast routing table (through RPF).
Examples
This example shows how to display all entries in the IP-multicast routing table:
Router# show ip mroute 224.1.1.1

Usage Guidelines
Use the show ip wccp service-number command to provide the "Total Packets Redirected" count. The "Total Packets Redirected" count is the number of flows, or sessions, that are redirected.
Use the show ip wccp service-number detail command to provide the "Packets Redirected" count. The "Packets Redirected" count is the number of flows, or sessions, that are redirected.
Use the show ip wccp web-cache detail command to provide an indication of how many flows, rather than packets, are using Layer 2 redirection.
For cache-engine clusters using Cisco cache engines, the reverse proxy service-number is indicated by a value of 99.
Use the clear ip wccp command to reset the counter for the "Packets Redirected" information.
For additional information on the IP WCCP commands, refer to the "Configuring Web Cache Services Using WCCP" section in the Cisco IOS Configuration Fundamentals Configuration Guide.
Examples
This example shows how to display the connected cache engine using Layer 2 redirection:

Support for this command was introduced. |
Usage Guidelines
Use the show ipv6 mfib command to display MFIB entries, forwarding interfaces, and their traffic statistics. This command can be enabled on virtual IP (VIP) if the router is operating in distributed mode.
Use the show ipv6 mfib active command to display MFIB entries actively used to forward packets. In many cases, it is useful to provide the optional kbps argument to display the set of entries that are forwarding an amount of traffic larger or equal to the amount set by the kbps argument.
Use the show ipv6 mfib count command to display the average packet size and data rate in kilobits per seconds.
The prefix-length is the length of the IPv6 prefix. A decimal value that indicates how many of the high-order contiguous bits of the address comprise the prefix (the network portion of the address). A slash mark must precede the decimal value.
A forwarding entry in the MFIB has flags that determine the default forwarding and signaling behavior to use for packets matching the entry. The entry also has per-interface flags that further specify the forwarding behavior for packets received or forwarded on specific interfaces. Table 2-71 describes the MFIB forwarding entries and interface flags.
Examples
This example shows how to display information for a specific group IPv6 address:

Usage Guidelines
If you do not specify a module number, the output of the show mac-address-table command displays information about the supervisor engine. To display information about the MAC-address table of the switch processor, you must enter the all keyword.
The mac-addr is a 48-bit MAC address and the valid format is H.H.H.
The interface-number argument designates the module and port number. Valid values for interface-number depend on the specified interface type and the chassis and module that are used. For example, if you specify a Gigabit Ethernet interface and have a 48-port 10/100BASE-T Ethernet module that is 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.
Valid values for mac-group-address are from 1 to 9.
The optional count keyword displays the number of multicast entries.
The optional multicast keyword displays the multicast MAC addresses (groups) in a VLAN or displays all statically installed or IGMP snooping-learned entries in the Layer 2 table.
The information that is displayed in the show mac-address-table unicast-flood command output is as follows:
•Up to 50 flood entries, shared across all the VLANs that are not configured to use the filter mode, can be recorded.
•The output field displays are defined as follows:
–ALERT—Information is updated approximately every 3 seconds.
–SHUTDOWN—Information is updated approximately every 3 seconds.
Note The information displayed on the destination MAC addresses is deleted as soon as the floods stop after the port shuts down.
–Information is updated each time that you install the filter. The information lasts until you remove the filter.
The show mac-address-table protocol {assigned | ip | ipx | other} syntax is not supported on Catalyst 6500 series switches that are configured with a Supervisor Engine 720.
The keyword definitions for the protocol argument are as follows:
•assigned specifies assigned protocol entries.
•ip specifies IP protocol.
•ipx specifies IPX protocols.
•other specifies other protocol entries.
The dynamic entries that are displayed in the Learn field are always set to Yes.
The show mac-address-table limit command output displays the following information:
•The current number of MAC addresses.
•The maximum number of MAC entries that are allowed.
•The percentage of usage.
The show mac-address-table synchronize statistics command output displays the following information:
•Number of messages processed at each time interval.
•Number of active entries sent for synchronization.
•Number of entries updated, created, ignored, or failed.
