atmIfCACbrMinPerVcQueueLimit

Module: Nortel-Magellan-Passport-AtmCoreMIB

OID (symbolic): Nortel-Magellan-Passport-AtmCoreMIB::atmIfCACbrMinPerVcQueueLimit

OID (numeric): 1.3.6.1.4.1.562.2.4.1.114.3.2.100.1.80

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

Description: This attribute specifies the minimum queue limit for the per-VC queues of connections of the CBR service category.

This attribute is ignored on CQC-based ATM cards, because they do not support per-VC queues at the CBR service category.

The queue limit of a per-VC queue is obtained by scaling down the txQueueLimit based on the shaping rate of that queue (shaping rate for the connection, and for standard Vpt Vccs, the shaping rate of the Vpt). This produces a constant delay for various queue lengths. The txQueueLimit provides an upper bound while minPerVcQueueLimit provides the lower bound. The value of this attribute must not be greater than the value of the txQueueLimit attribute. If this service category is used by Trunks the value of minPerVcQueueLimit must be at least 88.

For Vpts, this attribute does not apply. Regardless of Vpt service category, standard Vpts always use the AtmIf Ca NrtVbr minPerVcQueueLimit value as their default. To determine the queue limit of a standard Vpt Vcc, the txQueueLimit is scaled down by the Vpt shaping rate.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.562.2.4.1.114.3.2.100.1.80
snmpwalk -v2c -c public <target> Nortel-Magellan-Passport-AtmCoreMIB::atmIfCACbrMinPerVcQueueLimit

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.562.2.4.1.114.3.2.100.1.80.1
snmpget -v2c -c public <target> Nortel-Magellan-Passport-AtmCoreMIB::atmIfCACbrMinPerVcQueueLimit.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.562.2.4.1.114.3.2.100.1.80.1 i <value>
