What is phivCircuitCountUsrBuffUnav?

Cumulative count of times a packet on this circuit couldn't be processed because no user buffer was available, since the counters were last zeroed; a rising count suggests the host is running low on buffer resources under load.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.18.6.2.1.17
