Hi everyone.
Apparently the latest release for the ERS2500 includes a DHCP server. There is already documentation on how to configure it etc.
Here's the scenario. I have a branch office where we're going to deploy VoIP - new PBX (Avaya CS1000 of course ), cabling, network, the works. Part of the PBX order contains ERS2500 swtiches to provide IP connectivity (TLAN, ELAN etc.) for the PBX. The network design will have an ERS 5530 at the core and ERS 4500s at the edge.
Presently, this site receives DHCP from the main site over the MPLS WAN - there are no servers at the branch. Since the phones will be dependant on DHCP they will not work if the WAN goes down - even though the PBX could be up and running - this is not acceptable.
I was battling with how to deal with this problem until I discovered the DHCP server on the ERS 2500 rel 4.4. You see where I'm going with this... I want to use the ERS 2500 to provide DHCP to the phones (the PCs can fend for themselves. LOL!!).
Has anyone tried using the DHCP server on the ERS 2500? How does it relate to using the Windows DHCP server in terms of configuration? In reading the documentation from Avaya (Configuration — IP Routing and Multicast Avaya Ethernet Routing Switch 2500 Series NN47215-503, 05.02), I cannot see anyway to include the DHCP string you'd normally use for IP phones - Option 128, 191 etc.
I guess the real question is, how much information can I supply the IP phones via DHCP if I'm using the ERS 2500 instead of a Windows server?
If it is that I can only provide an IP address, how can I provide the other information to the IP phone - which automatic provisioning method should I use? ADAC, LLDP-MED?
Thanks in advance.
