Displaying information about an upstream neighbor device
You can view information about the upstream neighbor device for a given source IP address for IP
Protocol Independent Multicast (PIM). For PIM, the software uses the IP route table or multicast
route table to lookup the upstream neighbor device.
Enter the following command at the Privileged EXEC level of the CLI.
PowerConnect#show ip pim rpf 1.1.20.2
directly connected or through an L2 neighbor
Syntax: show ip pim | dvmrp rpf <IP address>
where <IP address> is a valid source IP address
NOTE
If there are multiple equal cost paths to the source, the show ip pim rpf command output may not
be accurate. If your system has multiple equal cost paths, use the command show ip pim mcache
to view information about the upstream neighbor.
Displaying the PIM flow cache
To display the PIM flow cache, enter the following command at any CLI level.
Syntax: show ip pim flowcache
This display shows the following information.
Age sec The number of seconds since the Layer 3 Switch received the last hello message from the
neighbor.
UpTime sec The number of seconds the PIM neighbor has been up. This timer starts when the Layer 3
Switch receives the first Hello messages from the neighbor.
