Configuring PIM-SM
Summit 200 Series Switch Installation and User Guide 231
For example, the following command statically configures an RP and its associated groups defined in
access profile rp-list:
configure pim crp static 10.0.3.1 rp-list
To configure the candidate RP advertising interval for PIM-SM timers, enter this command:
configure pim timer <hello interval> <join prune interval> vlan [<vlan
name>]
Specify the intervals in seconds. The hello interval specifies the amount of time before a hello
message is sent out by the PIM router. The join prune interval is the amount of time before a join or a
prune command is executed. The valid range for both intervals is 1 to 65,519 seconds. The default for
the
hello interval is 30 seconds; the default for join prune is 60 seconds.
Because PIM leverages the unicast routing capability that is already present in the switch, the access
policy capabilities are, by nature, different. When the PIM protocol is used for routing IP multicast
traffic, the switch can be configured to use an access profile to determine trusted PIM router neighbors
for the VLAN on the switch running PIM. To configure a trusted neighbor policy enter the following
command:
configure pim vlan [<vlan name> | all] trusted-gateway [<access profile>
|none]
For example, the following command configures a trusted neighbor policy on the VLAN backbone:
configure pim vlan backbone trusted-gateway nointernet
To configure the threshold (in Kbps) for switching to SPT, enter the following command:
configure pim spt-threshold <last hop router threshold> <rp threshold>
On leaf routers, this setting is based on data packets. On the RP, this setting is based on register packet
rate in Kbps.
The following command configures the checksum computation to either include data (for compatibility
with Cisco Systems products) or to exclude data (for RFC-compliant operation), in the register message:
configure pim register-checksum-to [include-data | exclude-data]
Enabling and Disabling PIM-SM
To enable or disable IP multicast routing on an interface, enter the following command:
[enable | disable] ipmcforwarding {<vlan> <vlan name>}
If the vlan option is not supplied, IP multicast cache (ipmc) routing is enabled or disabled on all
VLANs. Due to hardware limitations, a port can only be placed into a single VLAN that has IP
multicast routing enabled.
To enable or disable PIM-SM on the system, enter the following command:
[enable | disable] pim
To display the PIM configuration and statistics, enter the following command:
show pim {detail | rp-set | {vlan} <vlan name>}
