Hi Experts,

I have done a MAC binding for a MAC address AA3F920B9BF0 with a 10.88.69.62 in our DHCP. But when this MAC address request for DORA process it does not get the binded IP.  

In DHCP Server Log I have founded this log for the MAC

15,02/04/15,09:34:13,NACK,10.88.68.177,,AA3F920B9BF0,,0,6,,,

1. Could you please let me know what every word and number indicates here (ex - 0, 6) ?

Hi,

Each line record in DHCP audit log corresponding to:
ID, Date, Time, Description, IP Address, Host Name, MAC Address, User Name, TransactionID,  QResult, Probationtime, CorrelationID, Dhcid, VendorClass(Hex), VendorClass(ASCII), UserClass(Hex), UserClass(ASCII), RelayAgentInformation, DnsRegError.

Each Item is separated with comma. So TransactionID 0, and QResult -6.

Explaine to QResult:
0: NoQuarantine
1:Quarantine
2:Drop Packet
3:Probation
6:No Quarantine Information ProbationTime:Year-Month-Day Hour:Minute:Second:MilliSecond.
