lportCongestRateThresh
Module: CASCADE-MIB
OID (symbolic): CASCADE-MIB::lportCongestRateThresh
OID (numeric): 1.3.6.1.4.1.277.1.5.1.1.43
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The alert threshold (%) for the CongestRate; trap will be sent when exceeded.
What is lportCongestRateThresh?
This sets the percentage threshold that, once lportCongestRate exceeds it, causes the switch to send a trap alerting operations staff to sustained congestion on this port. An admin tunes this threshold to balance early warning against alert fatigue, since too low a setting and minor traffic bursts spam the NMS, while too high and real problems go unnoticed. For example, setting lportCongestRateThresh to 25 means the port will fire a trap as soon as more than a quarter of the last measurement interval was spent in severe or absolute congestion.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.5.1.1.43 snmpwalk -v2c -c public <target> CASCADE-MIB::lportCongestRateThresh
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.5.1.1.43.1 snmpget -v2c -c public <target> CASCADE-MIB::lportCongestRateThresh.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.277.1.5.1.1.43.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> lportCongestRateThresh.1
