Catalyst 4500 Series Switch Cisco IOS Command Reference—Release IOS XE 3.4.0SG and IOS 15.1(2)SG)
Description
Address of the RP switch. For switches and access servers
operating in sparse mode, this address is always 0.0.0.0.
Information about the entry.
Expected interface for a multicast packet from the source. If the
packet is not received on this interface, it is discarded.
IP address of the upstream switch to the source. "Tunneling"
indicates that this switch 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.
Status of whether the RPF information is obtained from the
DVMRP routing table or the static mroutes configuration.
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.
Name and number of the outgoing interface.
Next hop specifies downstream neighbor's IP address. VCD
specifies the virtual circuit descriptor number. VCD0 indicates that
the group is using the static-map virtual circuit.
Status of the packets; indicates if they are they 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).
Sparse mode interface is in forward mode.
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.
Description
Enables IP multicast routing.
Enables Protocol Independent Multicast (PIM) on an
interface.
