Dan,

Ohhh.. Its a little Tough... after looking at the HP switch config... I will try to convert this config as best as I can...

On HP Switch, port 19-20 are configured as trunk links with LACP port chanelling to some other switch. Please check and confirm... Do the following on 3550:

Config t

Interface fa 0/19

Switchport trunk encapsulation dot1q

switchport mode trunk

Interface fa 0/20

Switchport trunk encapsulation dot1q

switchport mode trunk

Check if you are using the port-channel (just to be sure) and then configure the portchannel using the link below on port 19 and 20.

Once this is done, configure the " IP routing " and Layer-3 SVI's along with the helper address to direct the DHCP broadcaststs to the DHCP server.

Config t

IP routing

Interface vlan 10

ip address xxx.xxx.xxx.xxx 255.255.255.252

ip helper-address xxx.xxx.xxx.xxx

Interface vlan 210

ip address xxx.xxx.xxx.xxx 255.255.255.0

ip helper-address xxx.xxx.xxx.xxx

Interface vlan 300

ip address xxx.xxx.xxx.xxx 255.255.254.0

ip helper-address xxx.xxx.xxx.xxx

Ip route 0.0.0.0 0.0.0.0 xxx.xxx.xxx.xxx

I see that IGMP has been enabled on the HP switch. You can enable the same using the following links:

Please find the 3550 Config guide below for configuration.
