portPVCOptimization

Module: FRX-MIB

OID (symbolic): FRX-MIB::portPVCOptimization

OID (numeric): 1.3.6.1.4.1.177.3.3.1.1.21

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Enables or disables route optimization per DLCI on a port. Enabling this feature may seriously degrade performance in systems with high speed (greater than 1.024 Mbps) ports. Frames may be lost.

What is portPVCOptimization?

Turns on per-DLCI route optimization for PVCs on this port; like per-DLCI accounting, the source warns this can seriously degrade performance and drop frames above 1.024 Mbps, so it's a feature to weigh against throughput.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.177.3.3.1.1.21
snmpwalk -v2c -c public <target> FRX-MIB::portPVCOptimization

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.177.3.3.1.1.21.1
snmpget -v2c -c public <target> FRX-MIB::portPVCOptimization.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.177.3.3.1.1.21.1 i <value>

Start monitoring Legacy frame relay switch/access node (Netrix/FastComm-style FRX platform) with a free 30-day trial of IPNetwork Monitor. Create custom SNMP monitor using the FRX-MIB::portPVCOptimization OID value, configure state conditions and alerts, and monitor any Legacy frame relay switch/access node (Netrix/FastComm-style FRX platform) from a single console.
