So there are routers requesting DHCP option 212, 6rd IPv6 Rapid Deployment. Powercode doesnt send this out in its response, so I think this is what causes our DHCP logs to fill up (the client just keeps requesting over and over and over)
I have read in the past generic NULL type responses that can be given to stop various requests from continuing repetitively Is anyone aware of what would need to be in the response to basically tell it to shut up, but not impact functionality? this is a packet capture showing the 212 option being requested but not delivered: 01:39:38.939174 00:0d:b9:07:c6:7c > 00:90:0b:2f:89:af, ethertype IPv4 (0x0800), length 342: (tos 0x0, ttl 63, id 0, offset 0, flags [DF], proto: UDP (17), length: 328) 10.0.50.185.68 > BLANKED.67: BOOTP/DHCP, Request from c8:d7:19:78:70:e4, length 300, xid 0xc3746f0a, secs 8724, Flags [ none ] Client-IP 10.0.50.185 Client-Ethernet-Address c8:d7:19:78:70:e4 Vendor-rfc1048 Extensions Magic Cookie 0x63825363 DHCP-Message Option 53, length 1: Request Hostname Option 12, length 15: "*****" Parameter-Request Option 55, length 5: Subnet-Mask, Default-Gateway, Domain-Name, Domain-Name-Server *Option 212* Client-ID Option 61, length 7: ether c8:d7:19:78:70:e4 01:39:38.950040 00:90:0b:2f:89:af > 00:0d:b9:07:c6:7c, ethertype IPv4 (0x0800), length 342: (tos 0x0, ttl 64, id 37727, offset 0, flags [DF], proto: UDP (17), length: 328) 10.6.0.29.67 > 10.0.50.185.68: BOOTP/DHCP, Reply, length 300, xid 0xc3746f0a, secs 8724, Flags [ none ] Client-IP 10.0.50.185 Your-IP 10.0.50.185 Client-Ethernet-Address c8:d7:19:78:70:e4 Vendor-rfc1048 Extensions Magic Cookie 0x63825363 DHCP-Message Option 53, length 1: ACK Server-ID Option 54, length 4: BLANKED Lease-Time Option 51, length 4: 86400 Subnet-Mask Option 1, length 4: 255.255.255.0 Default-Gateway Option 3, length 4: 10.0.50.1 Domain-Name-Server Option 6, length 8: 208.67.222.222,208.67.220.220 -- If you only see yourself as part of the team but you don't see your team as part of yourself you have already failed as part of the team.
