ubiDhcpCurPktNak
Module: UBQS-DHCP-MIB
OID (symbolic): UBQS-DHCP-MIB::ubiDhcpCurPktNak
OID (numeric): 1.3.6.1.4.1.7800.100.6.1.1.1.12
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: The number of offer messages sent to dhcp servers.
What is ubiDhcpCurPktNak?
Counts DHCPNAK messages the server has sent to clients, rejecting a requested address (e.g. because the client asked for a lease on the wrong subnet or one already in use). Note: like ubiDhcpCurPktAck, the source description here is copy-pasted from ubiDhcpCurPktOffer and wrongly says 'offer messages' - the object's own name and OID position confirm it is actually the NAK counter. A rising NAK count relative to offers/acks is worth investigating for pool/subnet misconfiguration.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.7800.100.6.1.1.1.12 snmpwalk -v2c -c public <target> UBQS-DHCP-MIB::ubiDhcpCurPktNak
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.7800.100.6.1.1.1.12.1 snmpget -v2c -c public <target> UBQS-DHCP-MIB::ubiDhcpCurPktNak.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ubiDhcpCurPktNak.1
