lpEngArcOvTxCellMemoryAllocation
Module: Nortel-Magellan-Passport-AtmBaseMIB
OID (symbolic): Nortel-Magellan-Passport-AtmBaseMIB::lpEngArcOvTxCellMemoryAllocation
OID (numeric): 1.3.6.1.4.1.562.2.4.1.12.23.5.2.10.1.3
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: This attribute specifies the fraction of the transmit memory which should be allocated to the transmission of cells on an FP. The remaining memory is allocated for the transmission of frames. Frame memory is used for trunks, ATM VCC testing and for inter- card communication. Cell memory is used for Atm Bearer Service, ATM SVCs and ATM PVCs.
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 allocates the minimum required, rather than the actual number requested.
The actual percentage of the transmit memory allocated to the transmit cell memory is indicated by the Arc txCellMemoryAllocation 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 lpEngArcOvTxCellMemoryAllocation?
Sets what fraction (1-99, default 50) of this FP's transmit memory should go to cell traffic (ATM Bearer Service, SVCs, PVCs) rather than frame traffic (trunks, VCC testing, inter-card messages); the FP-enforced minimum frame-buffer count means the applied value, shown in lpEngArcTxCellMemoryAllocation, may differ slightly from what was set here.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.562.2.4.1.12.23.5.2.10.1.3 snmpwalk -v2c -c public <target> Nortel-Magellan-Passport-AtmBaseMIB::lpEngArcOvTxCellMemoryAllocation
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.562.2.4.1.12.23.5.2.10.1.3.1 snmpget -v2c -c public <target> Nortel-Magellan-Passport-AtmBaseMIB::lpEngArcOvTxCellMemoryAllocation.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.562.2.4.1.12.23.5.2.10.1.3.1 i <value>
