IP-Helper Adress not working for a single VLAN
Hi,
im running a pair of 4128F-ON as VLT.
I have configured some VLANs. With the command "ip-helper address" I pass on the DHCP server in these VLANs. Works quite well, except for my VLAN 9 (Phones).
The phones do not get a DHCP address, the DHCP broadcasts do not arrive at the DHCP server.
Client PCs in another VLAN get their addresses assigned, the ip-helper command works fine in other VLANS.
The DHCP server is reachable from the phone VLAN (and vice versa).
Does anyone have a hint or similar problems? Are there any limitations that I have missed?

Hello,
Could you try removing or deleting the lease addresses, in DHCP, I wonder if it's because of this.
Check if the DHCP server is on the correct gateway.
Hope this helps!
