Description: Congestion Window Reduced Packets
What is tcpv4CwrVal?
This counter measures the total number of TCP IPv4 packets that have had their Congestion Window Reduced (CWR) flag set, indicating network congestion response. The CWR flag is sent by a source that has reduced its sending rate in response to explicit congestion notification. Network analysts use this metric to assess how often congestion occurs and the effectiveness of end-to-end congestion control mechanisms.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.15397.2.1.48.41.1 snmpwalk -v2c -c public <target> PACKETLOGIC-MIB::tcpv4CwrVal
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.15397.2.1.48.41.1.1 snmpget -v2c -c public <target> PACKETLOGIC-MIB::tcpv4CwrVal.1
