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.
