12.1(13)E	Support for this command on the Catalyst 6500 series switches was extended to the 12.1 E release. Valid values for port-channel number was increased to 282.

Usage Guidelines

The number of valid values for port-channel number depends on the software release. For releases prior to Release 12.1(3a)E3, valid values are from 1 to 256; for Releases 12.1(3a)E3, 12.1(3a)E4, and 12.1(4)E1, valid values are from 1 to 64. Release 12.1(5c)EX and later support a maximum of 64 values ranging from 1 to 256. Release 12.1(13)E and later support a maximum of 64 values ranging from 1 to 282; values 257 to 282 are supported on the CSM and FWSM.

If your system is configured with a Supervisor Engine 1, valid values for vlan-id are from 1 to 1005. If your system is configured with a Supervisor Engine 2, valid values for vlan-id are from 1 to 4094. Extended-range VLANs are not supported on systems configured with a Supervisor Engine 1.

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 used. For example, if you specify a Gigabit Ethernet interface and have a 48-port 10/100BASE-T Ethernet module installed in a 13-slot chassis, valid values for the module number are from 2 to 13 and valid values for the port number are from 1 to 48.

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 RPF).

Table 2-34 explains the fields shown in the displays.

Table 2-34 show ip mroute Field Descriptions 

Field	Description
Flags:	Information about the entry.
D - Dense	Entry is operating in dense mode.
S - Sparse	Entry is operating in sparse mode.
s - SSM Group	Entry is a member of an SSM group.
C - Connected	Member of the multicast group is present on the directly connected interface.
L - Local	Router itself is a member of the multicast group.
P - Pruned	Route has been pruned. This information is retained in case a downstream member wants to join the source.
R - Rp-bit set	Status of whether the (S,G) entry is pointing toward the RP. This is typically a prune state along the shared tree for a particular source.
F - Register flag	Status of whether the software is registering for a multicast source.
T - SPT-bit set	Status of whether the packets have been received on the shortest path source tree.
J - Join SPT	For (*, G) entries, indicates that the rate of traffic flowing down the shared tree is exceeding the SPT-Threshold set for the group. (The default SPT-Threshold setting is 0 kbps.) When the J - Join SPT flag is set, the next (S,G) packet received down the shared tree triggers an (S,G) join in the direction of the source causing the router to join the source tree. For (S,G) entries, indicates that the entry was created because the SPT-Threshold for the group was exceeded. When the J - Join SPT flag is set for (S,G) entries, the router monitors the traffic rate on the source tree and attempts to switch back to the shared tree for this source if the traffic rate on the source tree falls below the group's SPT-Threshold for more than one minute. The router measures the traffic rate on the shared tree and compares the measured rate to the group's SPT-Threshold once every second. If the traffic rate exceeds the SPT-Threshold, the J - Join SPT flag is set on the (*, G) entry until the next measurement of the traffic rate. The flag is cleared when the next packet arrives on the shared tree and a new measurement interval is started. If the default SPT-Threshold value of 0 Kbps is used for the group, the J - Join SPT flag is always set on (*, G) entries and is never cleared. When the default SPT-Threshold value is used, the router immediately switches to the shortest-path tree when traffic from a new source is received.
Outgoing interface flags:	Information about the outgoing entry.
H - Hardware switched	Entry is hardware switched.
Timers:	Uptime/Expires.
Interface state:	Interface, Next-Hop or VCD, State/Mode.
(*, 224.0.255.1) (198.92.37.100/32, 224.0.255.1)	Entry in the IP multicast routing table. The entry consists of the IP address of the source router followed by the IP address of the multicast group. An asterisk (*) in place of the source router indicates all sources. Entries in the first format are referred to as (*,G) or "star comma G" entries. Entries in the second format are referred to as (S,G) or "S comma G" entries. (*,G) entries are used to build (S,G) entries.
uptime	How long in hours, minutes, and seconds that the entry has been in the IP multicast routing table.
expires	How long in hours, minutes, and seconds until the entry is removed from the IP multicast routing table on the outgoing interface.
RP	Address of the RP router. For routers and access servers operating in sparse mode, this address is always 0.0.0.0.
flags:	Information about the entry.
Incoming interface:	Expected interface for a multicast packet from the source. If the packet is not received on this interface, it is discarded.
RPF neighbor	IP address of the upstream router to the source. "Tunneling" indicates that this router is sending data to the RP encapsulated in Register packets. The hexadecimal number in parentheses indicates to which RP it is registering. Each bit indicates a different RP if multiple RPs per group are used.
Dvmrp or Mroute	Status of whether the RPF information is obtained from the DVMRP routing table or the static mroutes configuration.
Outgoing interface list:	Interfaces through which packets are forwarded. When the ip pim nbma-mode command is enabled on the interface, the IP address of the PIM neighbor is also displayed.
Ethernet0	Name and number of the outgoing interface.
Next hop or VCD	Next hop specifies the downstream neighbor's IP address. VCD specifies the virtual circuit descriptor number. VCD0 means that the group is using the static-map virtual circuit.
Forward/Dense	Status of whether the packets are forwarded on the interface if there are no restrictions due to access lists or the TTL threshold. Following the slash (/), mode in which the interface is operating (dense or sparse).
Forward/Sparse	Sparse mode interface is in forward mode.
time/time (uptime/expiration time)	Per interface, how long in hours, minutes, and seconds the entry has been in the IP multicast routing table. Following the slash (/), how long in hours, minutes, and seconds until the entry is removed from the IP multicast routing table.

Release	Modification
12.0(7)XE	Support for this command was introduced on the Catalyst 6500 series switches.
12.1(1)E	Support for this command on the Catalyst 6500 series switches was extended to the 12.1 E release.
12.1(3a)E3	The number of valid values for port-channel changed; see the "Usage Guidelines" section for valid values.
12.1(11b)E	This command was changed to include the ge-wan, atm, and pos keywords.
12.1(11b)EX	The command was changed to support extended-range VLANs.

Usage Guidelines

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 used. For example, if you specify a Gigabit Ethernet interface and have a 48-port 10/100BASE-T Ethernet module installed in a 13-slot chassis, valid values for the module number are from 2 to 13 and valid values for the port number are from 1 to 48.

The number of valid values for port-channel number depends on the software release. For releases prior to Release 12.1(3a)E3, valid values are from 1 to 256; for Releases 12.1(3a)E3, 12.1(3a)E4, and 12.1(4)E1, valid values are from 1 to 64. Release 12.1(5c)EX and later support a maximum of 64 values ranging from 1 to 256. Release 12.1(13)E and later support a maximum of 64 values ranging from 1 to 282; values 257 to 282 are supported on the CSM and FWSM.

If your system is configured with a Supervisor Engine 1, valid values for vlan-id are from 1 to 1005. If your system is configured with a Supervisor Engine 2, valid values for vlan-id are from 1 to 4094. Extended-range VLANs are not supported on systems configured with a Supervisor Engine 1.
