i have a 3845 router and 3560 switch. i had an issue wherein i can't get my 1140e nortel ip phone settings (server unreachable) when connecting to 3560e switch. previously i was able to have it worked during my initial config (ip addressing, vlan and interface vlan configs) for the switch and router. and then i've added acl, qos etc along the way. then i tested my ip phone again, it doesn't get its config. from the switch, i can ping to our dhcp (172.25.22.10) and nortel pabx server (172.25.202.15) from vlan voice (vlan 1076) as source. i used the ip phone to troubleshoot, i can ping to the voice gw (172.25.227.253). my belief there's a line or config blocking my connection. i've exhausted all troubleshooting needed all day. i need a fresh set of eyes to look into my config and verify with me so that i can continue testing tomorrow. thanks in advance!
We ended up hard setting the information in the phones instead of using the DHCP options. We couldn't get it to pass everything correctly. I've attached a Nortel DHCP configuration guide.
Hope it helps.
