What is a3IPntmHdrFormat?

This OID specifies the packet header format used when transmitting to a particular network destination. Network engineers configure it to match the MAC-layer requirements of different network types (Ethernet, Token Ring, etc.). A typical value might be 'ethernet' for Ethernet networks; other network types return 'other'.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.43.2.6.7.1.3
snmpwalk -v2c -c public <target> A3COM-IPEXTNS-R5-MIB::a3IPntmHdrFormat

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.43.2.6.7.1.3.1
snmpget -v2c -c public <target> A3COM-IPEXTNS-R5-MIB::a3IPntmHdrFormat.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.43.2.6.7.1.3.1 i <value>
