What is accDnUnreachs?

This counter accumulates the number of packets that were dropped because the destination node was unreachable. Engineers monitor this metric to identify network connectivity problems or routing black holes. A counter value of 1523 indicates that 1523 packets destined for unreachable nodes have been discarded since the last reset.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5.1.1.19.16
snmpwalk -v2c -c public <target> ACC-MIB::accDnUnreachs

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.5.1.1.19.16.1
snmpget -v2c -c public <target> ACC-MIB::accDnUnreachs.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> accDnUnreachs.1
