What is nwAtFwdIfCtrHdrErrPkts?

This read-only Counter totals AppleTalk packets discarded on a specific router port during the current nwAtFwdIfCtrOperationalTime interval because of an invalid AppleTalk header. An administrator uses it to pinpoint which link is the source of header-corrupted AppleTalk traffic. Seeing this counter rise on only one of several ports narrows down a suspected cabling or NIC problem to that specific connection.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.4.2.2.2.2.1.1.12
snmpwalk -v2c -c public <target> CTRON-AppleTalk-ROUTER-MIB::nwAtFwdIfCtrHdrErrPkts

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.3.4.2.2.2.2.1.1.12.1
snmpget -v2c -c public <target> CTRON-AppleTalk-ROUTER-MIB::nwAtFwdIfCtrHdrErrPkts.1
