lpArcMulticastBranchesCapacity

Module: Nortel-Magellan-Passport-AtmBaseMIB

OID (symbolic): Nortel-Magellan-Passport-AtmBaseMIB::lpArcMulticastBranchesCapacity

OID (numeric): 1.3.6.1.4.1.562.2.4.1.12.19.100.1.6

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

Description: This attribute is migrated to the Lp/n Eng Arc Ov attribute of the same name.

This attribute specifies the number of multicast branches that can be enabled on the Logical Processor.

A multicast branch is used for cell replication on a Vcc connection whose Vcc distributionType is pointToMultipoint. A branch represent one ATM destination for the replicated cells

Increasing the value of this attribute reduces the CQM memory available for the cell and frame free lists.

What is lpArcMulticastBranchesCapacity?

Sets how many multicast cell-replication branches (destination endpoints for a point-to-multipoint VCC) the LogicalProcessor may enable, up to 10752. Raising this value reduces the CQM memory left over for the cell and frame free lists, so an admin should only increase it if the FP actually carries multicast VCCs.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.562.2.4.1.12.19.100.1.6
snmpwalk -v2c -c public <target> Nortel-Magellan-Passport-AtmBaseMIB::lpArcMulticastBranchesCapacity

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.562.2.4.1.12.19.100.1.6.1
snmpget -v2c -c public <target> Nortel-Magellan-Passport-AtmBaseMIB::lpArcMulticastBranchesCapacity.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.562.2.4.1.12.19.100.1.6.1 i <value>
