Software Version 7.6e.2.3 [non-ssh] by Release_Master on 08/29/06 05:02:55

I have a Shoretel Phone on a tagged VLAN 7 that boots up to VLAN 200 (Data) gets the tagged VLAN info from DHCP (Options 155 and 156) and attempts to boot up to VLAN 7 and then never gets a reply from DHCP server. WireShark shows that DHCP request is sent and DHCP Server receives it. DHCP responds but reply does not end up in VLAN 7. The phone just times out waiting for the reply (300+ seconds)

In the config, I have DHCP-Relay Enabled and IP Forwarding enabled for all vlans

# -- IP Interface[0] = "Default"
enable ipforwarding vlan "Default"
disable icmp timestamp vlan "Default"
disable icmp address-mask vlan "Default"

# -- IP Interface[5] = "MacVlanDiscover"
enable ipforwarding vlan "MacVlanDiscover"
disable icmp timestamp vlan "MacVlanDiscover"
disable icmp address-mask vlan "MacVlanDiscover"

# -- IP Interface[1] = "vlan_ss_ed"
enable ipforwarding vlan "vlan_ss_ed"
disable icmp timestamp vlan "vlan_ss_ed"
disable icmp address-mask vlan "vlan_ss_ed"

# -- IP Interface[2] = "vlan_data"
enable ipforwarding vlan "vlan_data"
disable icmp timestamp vlan "vlan_data"
disable icmp address-mask vlan "vlan_data"

# -- IP Interface[3] = "vlan_manage"
enable ipforwarding vlan "vlan_manage"
disable icmp timestamp vlan "vlan_manage"
disable icmp address-mask vlan "vlan_manage"

# -- IP Interface[4] = "vlan_voice"
enable ipforwarding vlan "vlan_voice"
disable icmp timestamp vlan "vlan_voice"
disable icmp address-mask vlan "vlan_voice"


# Global IP settings.
disable icmp access-list
enable iproute sharing
enable bootprelay
configure bootprelay add 172.20.42.150

Is there something more I need to do?

I have been working on this for 1+week with tech support and would really appreciate assistance. I have a test lab setup at my house to make changes without impacting production.

Thank You

Problem was solved last week. Turned of Tagged VLAN that was on the Port where DHCP server was plugged in. Should not have had to do that, but it worked.
