nodeCongestionLevel

Module: FRX-MIB

OID (symbolic): FRX-MIB::nodeCongestionLevel

OID (numeric): 1.3.6.1.4.1.177.3.2.7

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: The current state of congestion for the FRX node. The valid values are notCongested (normal operation), approachingCongestion (FECN and BECN are being set), congested (DE frames are being dropped), and fullyCongested (normal data frames are being dropped).

What is nodeCongestionLevel?

Reports the frame relay node's overall congestion state: notCongested under normal load, approachingCongestion once FECN/BECN bits are being set on frames, congested once DE-marked frames start getting dropped, and fullyCongested once even non-discard-eligible frames are dropped -- a quick health check an admin polls before diving into per-port statistics.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.177.3.2.7
snmpwalk -v2c -c public <target> FRX-MIB::nodeCongestionLevel

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.177.3.2.7.1
snmpget -v2c -c public <target> FRX-MIB::nodeCongestionLevel.1

SNMPv3 example:

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