Hi, I faced a very wired dhcp problem. I set up a router as dhcp server on subinterface. interface connected to switch and configured as a trunk.
I can see from debug that dhcp packets are exchanging between router and ipphone *Mar 2 03:14:01.547: DHCPD: DHCPDISCOVER received from client 0100.059b.f19c.4f on interface FastEthernet0/0.500. *Mar 2 03:14:01.547: DHCPD: Sending DHCPOFFER to client 0100.059b.f19c.4f (200.0.0.1). *Mar 2 03:14:01.551: DHCPD: broadcasting BOOTREPLY to client 0005.9bf1.9c4f. *Mar 2 03:14:01.555: DHCPD: DHCPREQUEST received from client 0100.059b.f19c.4f. *Mar 2 03:14:01.555: DHCPD: No default domain to append - abort update *Mar 2 03:14:01.555: DHCPD: Sending DHCPACK to client 0100.059b.f19c.4f (200.0.0.1). *Mar 2 03:14:01.559: DHCPD: broadcasting BOOTREPLY to client 0005.9bf1.9c4f. However I can see these 8 lines repeating every 3 seconds. Phone shows dhcp server 255.255.255.255 factory reset didn't help. Anybody face this before? Cheers, Jereny
