I'm new to Switches. I inherited 2 switches 3550 and 3560. My core switch is 3560 linked to 3550 on port 1. One of the vlan24 with IP 10.164.24.0 is not pointing request to my windows 2008 DHCP server for IP leases. I have a IP-Helper associated with the vlan24. I need all your help
ip address 10.164.24.1 255.255.255.128
ip helper-address 10.164.9.11
ip helper-address 10.164.9.18
also a show vlan has:

Solved! Go to Solution.
I would say yes because prior to me they used this vlan in conjuction with a scope in DHCP for all wireless devices. The scope still remains however, I've since replace the centrally managed WAP (Wireless Access Point) with AP541N
Is the DHCP service enabled on the switch acting as a relay agent?
To verify, output of sh run | i service dhcp should not be empty.
If it is not enabled, do it with global config command "service dhcp"
core#sh ip dhcp ?
