Module: Nortel-MsCarrier-MscPassport-VirtualRouterMIB

OID (symbolic): Nortel-MsCarrier-MscPassport-VirtualRouterMIB::mscVrMmVrMaxHeapSpace

OID (numeric): 1.3.6.1.4.1.562.36.2.1.100.2.10.1.1

Node type: OBJECT-TYPE

Access: read-write

Description: The maximum percentage of the total system heap space that is allowed for use by this Virtual Router. Memory allocation for this VR which attempts to exceed this limit will fail causing a shut down of the requesting process.

What is mscVrMmVrMaxHeapSpace?

This caps the percentage of the switch's total system heap memory this Virtual Router as a whole is allowed to use, defaulting to 100% (no effective cap). Exceeding this limit fails the allocation and shuts down the requesting process, so carriers lower this to keep one customer's Vr from starving others of memory.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.562.36.2.1.100.2.10.1.1
snmpwalk -v2c -c public <target> Nortel-MsCarrier-MscPassport-VirtualRouterMIB::mscVrMmVrMaxHeapSpace

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.562.36.2.1.100.2.10.1.1.1
snmpget -v2c -c public <target> Nortel-MsCarrier-MscPassport-VirtualRouterMIB::mscVrMmVrMaxHeapSpace.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.562.36.2.1.100.2.10.1.1.1 i <value>
