Displaying a list of multicast groups

To display a list of the IP multicast groups the Layer 3 Switch is forwarding, enter the following
command at any CLI level.

How many seconds the Layer 3 Switch will wait for a hello message from a neighbor
before determining that the neighbor is no longer present and removing cached PIM
Sparse forwarding entries for the neighbor.
How frequently the BSR configured on the Layer 3 Switch sends the RP set to the RPs
within the PIM Sparse domain. The RP set is a list of candidate RPs and their group
prefixes. A candidate RP group prefix indicates the range of PIM Sparse group numbers
for which it can be an RP.
NOTE: This field contains a value only if an interface on the Layer 3 Switch is elected to
be the BSR. Otherwise, the field is blank.
How frequently the candidate PR configured on the Layer 3 Switch sends candidate RP
advertisement messages to the BSR.
NOTE: This field contains a value only if an interface on the Layer 3 Switch is configured
as a candidate RP. Otherwise, the field is blank.
How frequently the Layer 3 Switch sends PIM Sparse Join/Prune messages for the
multicast groups it is forwarding. This field show the number of seconds between
Join/Prune messages.
The Layer 3 Switch sends Join/Prune messages on behalf of multicast receivers who
want to join or leave a PIM Sparse group. When forwarding packets from PIM Sparse
sources, the Layer 3 Switch sends the packets only on the interfaces on which it has
received join requests in Join/Prune messages for the source group.
You can change the Join/Prune interval if needed. Refer to
prune message interval"
The number of packets the Layer 3 Switch sends using the path through the RP before
switching to using the SPT path.
However, this command lists all IP multicast interfaces, including regular PIM (dense mode) and DVMRP
interfaces. The show ip pim sparse command lists only the PIM Sparse interfaces.
The type of interface and the interface number. The interface type can be one of the
following:
•
Ethernet
•
VE
The number is either a port number (and slot number if applicable) or the virtual interface
(VE) number.
Following the TTL threshold value, the interface state is listed. The interface state can be
one of the following:
•
Disabled
•
Enabled
Indicates the IP address configured on the port or virtual interface.
