What is clvSysTCPRecvSmall?
This read-only gauge reports current usage of the firewall's pool of small TCP receive-window buffers. It's a resource-utilization indicator for one of the internal buffer pools the firewall uses to manage TCP state, and sustained high usage can signal the appliance is under heavy small-packet TCP load. For example, an admin seeing clvSysTCPRecvSmall near its ceiling during peak hours might consider it a sign the firewall's TCP buffer pools need tuning.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5089.1.2.1.13.1 snmpwalk -v2c -c public <target> CLAVISTER-MIB::clvSysTCPRecvSmall
Get a specific instance (index 1):
