lpArcRxFrameMemoryAllocation

Module: Nortel-Magellan-Passport-AtmBaseMIB

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

OID (numeric): 1.3.6.1.4.1.562.2.4.1.12.19.100.1.20

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

Description: This attribute is migrated to the Lp/n Eng Arc Ov attribute rxCellMemoryAllocation. It is converted from frame percentage to cell percentage by subtracting this value from 100.

This attribute specifies the percentage of the receive CQM memory which should be allocated to the receive frame free list on the ATM- FP. The remaining receive CQM memory is allocated to the receive cell free list. Frame memory is used for trunks, ATM VCC testing and for inter-card communication. There is an absolute minimum quantity of frame buffers which is required by ATM software on the FP. If the value of this attribute is smaller than the absolute minimum, the ATM software will allocate the minimum required, rather than the actual number requested.

The actual percentage of the receive CQM memory allocated to the receive frame free list is indicated by the Aru rxFrameMemoryAllocation attribute. A difference between the provisioned and the operational values may exist due to the requirement for a minimum number of frame buffers or rounding during computation within the FP

What is lpArcRxFrameMemoryAllocation?

Sets what percentage (0-100, default 80) of the FP's receive CQM memory is reserved for the receive frame free list versus the receive cell free list. Because the FP enforces a minimum frame-buffer count, the value actually in effect can differ slightly from what was provisioned and is reported by the matching lpAru operational attribute.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.562.2.4.1.12.19.100.1.20
snmpwalk -v2c -c public <target> Nortel-Magellan-Passport-AtmBaseMIB::lpArcRxFrameMemoryAllocation

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.562.2.4.1.12.19.100.1.20.1
snmpget -v2c -c public <target> Nortel-Magellan-Passport-AtmBaseMIB::lpArcRxFrameMemoryAllocation.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.562.2.4.1.12.19.100.1.20.1 i <value>
