The voip phones are working in the Main office. I am trying to get a voip phone to office B. I am not getting an ip address from the DHCP server on vlan 24. I can get ip addresses from from the other vlans 4, and 12.
Main -> Office A -> Office B
The DHCP server is in the main office. Office A connects to the Main switch. Office B connects to the switch in office A using port 42. Office B switch port 8 is for the phones.
In Office A, I temporarly set an ip helper-address on the vlan 24 to 10.100.4.50 (DHCP). But this did not help.
How do I diagnose this problem? any hints on where the issue may be?
Thanks,
Office B switch config
