What is nwRtrIfFwdCtrHostDiscardBytes?

This OID counts the total bytes of routed-protocol packets received on this port and discarded by the local host. It's the byte-count counterpart to nwRtrIfFwdCtrHostDiscardPkts, useful for gauging how much locally-destined traffic is being dropped.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.2.4.2.1.1.21
snmpwalk -v2c -c public <target> CTRON-ROUTERS-MIB::nwRtrIfFwdCtrHostDiscardBytes

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.2.4.2.1.1.21.1
snmpget -v2c -c public <target> CTRON-ROUTERS-MIB::nwRtrIfFwdCtrHostDiscardBytes.1
