Shortel and Cisco switch configuration
Hello all,
I have looked at some of these posts, but none really address what I am trying to do.
Several sites on seperate subnets on default native vlan
192.168.102.x
192.168.103.x
192.168.104.x
S/M 255.255.255.0
Voice vlan ip as follows:
10.10.102.x
10.10.103.x
10.10.104.x
S/N 255.255.255.0
All default gateways are
x.x.x.1
We are putting in Shoretel system and are having trouble getting the vlans set up
All switches are Cisco 2950 and 2960 switches.
I have vlan 1 for the 192.168.x.x with subnet of 255.255.255.0
I have voice vlan for the 10.10.x.x with subnet of 255.255.255.0
The switches currently have the following commands on the ports:
switchport mode access
switchport voice vlan 5
no cdp enable
spanning-tree portfast
The port that will have the Shoregear switch plugged into it is configured as such:
description Uplink to Shoretel Switch
switchport trunk native vlan 5
no cdp enable
spanning-tree portfast
Uplink ports are:
switchport mode trunk
Now, the issue that I have at the moment is that most switches when issuing the no shut command on voice vlan 5, it will shut down vlan 1 (default native) and I lose remote access on the switch. What is wrong with the config? All ports need to be configured so that a PC and phone can be plugged into it. Also, the Shoretel server that will use both vlans as well.
Note...there will be no DHCP or auto config needed as the phones will be manually programmed.

To see what is wrong with the configuration, please post switch configuration without passwords, secrets, or other sensitive information. I believe you need to enable lldp globally for the switch to recognize your phones as phones so they can get the voice vlan.
I agree, we need the full config, but some suggestions:
Our switch port configs are basic (we use adtran but the ios is almost identical to cisco)
Here is a default access port
interface switchport 0/1
no shutdown
switchport mode trunk
qos trust cos
This would be an uplink to a shoregear switch
interface switchport 0/17
spanning-tree edgeport
no shutdown
switchport mode trunk
switchport voice vlan 5
qos trust cos
Manually programming the phones seems a bit tedious as well. I would recommend that you set option 156 in DHCP option 156 ascii "ftpservers=<IPOFYOURSHORE
Our ShoreTel server sits on the standard data vlan 1

The sites switch configs are pretty basic. I am not the one setting up the phones or Shoretel server. I am just facilitating the network config.
I have attached two switch sites. All ports are configured identically. (I cut out identical ports)
The goal is this:
Data vlan = vlan1
Voice = Vlan5
Keeping all Shoretel from touching data vlan, including server. The PC and phones will be daisy chained.
I don't have access to the routers, just the switches. I want to keep this as simple as possible. Problem I have is that vlan 5 is shutdown on the central site and when I run no shut on vlan5 , it shutsdown vlan1. I still have connectivity to the sites, but lose connectivity to the switches. What could be causing this as the remote site listed doesn't do this and I have never witnessed that type of behavior from a Cisco switch.

Kevin,
That is correct, the routers are handling the vlan routing.
So, i need to create a L2 interface or L3???
Also, enable lldp on all ports?

Just turn on lldp globally. Your switches need to have L2 VLANs created. Creating an additional L3 interface on an L2 switch isn't useful. I gave you exact syntax for all commands except for creating a username and password, since you should pick those yourself.

Ok. well. the ios is 12.1(22)
The lldp command doesn't seem to be available. And this is the last ios version available

LLDP is available on 2960 switches for sure because I run them. I don't know about 2950. the lldp run is not on an interface, but in the global configuration area.

Kevin,
I was unable to get LLDP on either the 2950 or 2960 in global config mode. However, with that said, I did get the issue worked out. The Shoretel switch port had to be put in access mode to work. There is no way to force the Shoretel switch itself to use vlan 5.
The phones come up and are able to communicate with the server and switches on the configured vlan.
