PIM-DM (Dense Mode) on the 5300xl Switches

Configuring PIM-DM on the Series 5300xl Switches

Syntax: router pim [state-refresh < 10 - 300 >]

Sets the interval in seconds between successive State Refresh

messages originated by the routing switch. Note that only

the routing switch connected directly to the unicast source

initiates state-refresh packets. All other PIM routers in the

network only propagate these state-refresh packets. (Default:

60 seconds)

Syntax: [no] router pim trap < all | neighbor-loss | hardware-mrt-full |

software-mrt-full>

Enables and disables these PIM SNMP traps:

all — Enable/Disable all PIM notification traps.

neighbor-loss — Enable/Disable the notification trap sent

when the timer for a multicast router neighbor expires and

the switch has no other multicast router neighbors on the

same VLAN with a lower IP address. (Default: Disabled.)

hardware-mrt-full — Enable/Disable notification trap when

the hardware multicast routing table (MRT) is full (1023

active flows). In this state, any additional flows are handled

by the software MRT, which increases processing time for

the affected flows. (Default: Disabled.)

software-mrt-full — Enable/Disable notification trap when

the routing switch’s software multicast routing table is full

(that is, when routing resources for active flows are

exhausted). (Default: Disabled.) Note that in this state, the

routing switch does not accept any additional flows.

Example of Configuring PIM at the Global Level. In figure 5-1 on page

5-6, the “5308XL #1” routing switch is directly connected to the multicast

sources for the network. In this case, suppose that you want to do the

following:

■ Reduce the state-refresh time from the default 60 seconds to 30 seconds.

Note that the routing switch transmits state-refresh packets only if it is

directly connected to the multicast source.

■ Configure an SNMP trap to notify your network management station if the

routing switch’s hardware multicast routing table becomes filled to the

maximum of 1023 active flows.
