What is usedPhyMemory?
usedPhyMemory reports how much of the switch's physical RAM is currently consumed, expressed as a string. Admins monitor this value over time to catch memory leaks or resource exhaustion in the switch's OS before it causes a crash or slowdown. For example, a rising usedPhyMemory trend approaching totalPhyMemory's value would prompt an admin to investigate a possibly misbehaving process on the switch.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.35098.1.3 snmpwalk -v2c -c public <target> PICA-PRIVATE-MIB::usedPhyMemory
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.35098.1.3.1 snmpget -v2c -c public <target> PICA-PRIVATE-MIB::usedPhyMemory.1
