What is ipIfInDiscards?
Counts IP packets received on this link that were otherwise valid but dropped because the router ran out of buffer space; a rising count under load is a sign of interface or CPU congestion.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.208.42.4.1.1.5 snmpwalk -v2c -c public <target> SCA-IPROUTER-MIB::ipIfInDiscards
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.208.42.4.1.1.5.1 snmpget -v2c -c public <target> SCA-IPROUTER-MIB::ipIfInDiscards.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ipIfInDiscards.1
