phivCircuitCountTransitCongestLoss

Module: RFC1289-phivMIB

OID (symbolic): RFC1289-phivMIB::phivCircuitCountTransitCongestLoss

OID (numeric): 1.3.6.1.2.1.18.6.2.1.8

Node type: OBJECT-TYPE

Type: PhivCounter

Access: read-only

Description: Number of transit congestion losses on this circuit.

What is phivCircuitCountTransitCongestLoss?

This counter tallies transit packets dropped on this circuit due to congestion (buffer exhaustion) while being forwarded through this node. A rising count signals this node is a bottleneck for traffic merely passing through, and may need more buffers (phivRouteMaxBuffs) or traffic engineering.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.18.6.2.1.8
snmpwalk -v2c -c public <target> RFC1289-phivMIB::phivCircuitCountTransitCongestLoss

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.18.6.2.1.8.1
snmpget -v2c -c public <target> RFC1289-phivMIB::phivCircuitCountTransitCongestLoss.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> phivCircuitCountTransitCongestLoss.1
