Hi! Using CNR Release 184.108.40.206 as DHCP server trying to get IP address through DHCP relay agent. CNR shows the following log:
FileName Match Line Number Log Number name_dhcp_1_log 4103 1 03/17/2010 15:32:02 name/dhcp/1 Info Failover 0 05991 Received DHCPDISCOVER packet from client Host: 'RoverbookU100' CID: 01:00:21:85:51:b9:33 but failover load balancing in state of normal did not allow network '192.168.1.0'to respond to this client. Dropping packet.
This message is perfectly normal which means that you have configured failover Load Balancing and the request is not being processed by this server as it is expecting the failover partner to process the request.
Now, you should find this processed in the failover partner (as that is how load balancing works). If you dont find the corresponding message on the partner, this indicates a misconfigured relay-agent. (i.e. one that wasn't relaying the DHCP traffic to both failover partners) and they could be locally connected clients which means the clients are on the same interface to which the servers are connected which in turn would imply that the DHCPDISCOVERs sent were not broadcast, but unicast to the server which violates the DHCP protocol. Remember, the DHCPDISCOVERs are always broadcast.!!
Hi everyone, I would like to thank you in advance for any help you can provide a newcomer like myself!
