What is accDnUnreachs?
ACC-DN::accDnUnreachs counts the total number of DECnet packets that were dropped because the destination node could not be reached. Network engineers watch this counter to detect routing problems or network connectivity issues with specific nodes. If this counter increases rapidly, it suggests a path failure or that some nodes are offline.
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-DN::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-DN::accDnUnreachs.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> accDnUnreachs.1
