the current flow or receives state-refresh packets for the current flow from another upstream multicast
router.
• Reset by a new flow for the current multicast group on the VLAN.
• The timer expires (reaches 0.) In this case, the switch has not received either a state-refresh packet or
new traffic for the current multicast group and ages-out (drops) the group entry.
DR Priority
Shows the currently configured priority for DR operation on the interface.

Display pending join requests
Use the
show ip pim pending
command to display the pending joins on a PIM router. A pending join can be
an IGMPv2 join (host join) or PIM (*,G) or (S,G) join (PIM router joins, PIM-SM only) received by a router for
which there is no active multicast flow to satisfy the received join. This aids in determining what flows are being
requested on the PIM network, but for which there is no data. If data availability is expected for a flow, and a join
for that flow is showing as pending, this moves the troubleshooting search to the source of the flow since the
routers are verified to be seeing the request for data.
Syntax:
show ip pim pending [
ip-address
]
Displays the joins received on the switch from downstream devices that want to join a specified (*,G) or (S,G)
multicast group (flow) address or all multicast groups known on the switch.
A join remains in a pending state until traffic is received for the flow. The VLAN (PIM interface) on which each join
was received is also displayed.
