DHCP/VPN Issue

DHCP/VPN Issue

DHCP/VPN Issue

(OP)

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.

RE: DHCP/VPN Issue

If the switch has a DHCP relay or IP Forwarder option you need to check this points at the DHCP server.

Also check that the scope for the particular VLAN exists on the server and has not been de-activated by mistake.
