We have an existing P550 switch that has stopped allowing 1 VLAN from getting an IP address from the DHCP server. From the DHCP Server I can ping the VLAN interface that is on the effected P550. If I assign this VLAN to a port and configure a system with a manual IP address on that particular VLAN, it will work fine. It only seems to effect DHCP on that VLAN. All other VLAN's can get an address. I have confirmed that the DHCP scope for that VLAN is configured properly. Again, it was working one day but not the next.
Any help would be appreciated.
