What is arp1PhysicalAddr?
This OID stores the 6-byte MAC address (physical address) of an ARP table entry on the first port. Network engineers examine this when troubleshooting layer 2 communication problems or verifying that devices are properly registered on the network. A value of '00:1a:2b:3c:4d:5e' represents the MAC address of a device connected to the switch's first interface.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.20.1.1.4 snmpwalk -v2c -c public <target> ACMIB::arp1PhysicalAddr
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.20.1.1.4.1 snmpget -v2c -c public <target> ACMIB::arp1PhysicalAddr.1
