VLANs and POE

[iflyvfr]

End user here. We are getting ready to install a ST system with approximately 90 phones connecting back to a Cisco 6500 series Catalyst switch w/ POE blades.

My plan had been to plug a single CAT6 cable run into the phone and then the PC. However, the Cisco installers were planning to do VLAN's for the IP phones. Can this still be done or do I need to run a separate cable for each device? We are moving into a new building and getting ready to cable so this issue needs to be decided pretty quickly.

Any real world advice greatly appreciated.

You can absolutely just have a single run to the phone and plug the PC in and have seperate VLANS (this is how we normally do deloyments). You will just configure the phone for vlan tagging (for the voice vlan) and you will configure your data vlan (for the PC) as untagged on the switch port.

Cisco does it a little bit different so I couldn't give you the exact commands (could help you if you had foundry, HP, extreme or juniper).

Cisco Config

I just got done configuring a cisco switch for this. Here are the commands I use to program a specific port:
conf t
int (port #)
switchport access vlan 201
switchport mode access
switchport voice vlan 204
switchport port-security
switchport port-security maximum 3
switchport port-security violation restrict
switchport port-security aging time 2
switchport port-security aging type inactivity
spanning-tree portfast
spanning-tree bpduguard enable

You also have to add the vlan to the switch:
conf t
vlan ###
Name (insert name)
ctrl z

Find the closest neighbor because the vlan has to be allowed on all the connecting ports between here and the core
sho cdp neighbor
conf t
int (port where the neighbor comes in)
switchport trunk allow vlan (all vlans that are on this switch plus the new one)
dont forget copy run start

Do the switchport trunk command on all connecting ports. Otherwise you'll be chasing your tail.


Hope this helps.

Your Shoretel equipment will go in vlan 221.
