I have a site that has 6 vlans.
The Default gateway is a 5412ZL Switch. Routing Enabled.
Vlan 2 is client computers Vlan 3 is servers Vlan 4 Is IP phones Vlan 5 Legacy Network Vlan 8 PCI
Phones are Shoretel IP230 Phones
I can take a laptop or desktop and plug it into any of the ports of the switch and it will get an ip for that vlan. If i take a IP phone and plug it into any of the vlans it fails.
All ports are tagged in Vlan4 and untagged in all the rest.
Each vlan has a ip helper with the ip of the dns server
each vlan has a Default gateway.
in the dhcpsrvlog
32,12/10/12,13:15:53,DNS Update Successful,10.1.10.200,DELL6520.
the mac address belongs to the IP phone
removing the lease and resetting the phone has not resolved the issue. rebuilding dhcp has not as well.
I ran a packet capture and
I have 2 attachments from the capture the DHCP Discover
As you can see from the Next packet i had set up dhcp reservation for the phone in question it appears the dhcp server is doing the correct thing but the phone never gets it
Im at a loss at where the issue is. Hp states the issue is with the DHCP server Shoretel states its a issue with the server as well.
I have not rebooted the switch as if that doesn't fix the issue all the ip phones may not come back on line as they are all POE
Sounds like a DHCP option is missing that the Shortel phones need.
If the necessary option exists, and it's a server option and not a scope option, your IP helper/relay agent (shown in the capture) should make sure any and all DHCP clients get their respective options. However, if that is not working, I recommend checking the VLAN config to make sure the helper is configured properly.
