Hi all,
We have a DR hosting site and their voice VLAN is 800 and our Voice VLAN is 100.
What I am trying to do it to get the phones on the DR Site (VLAN800) to register with the phone on the main network (VLAN100).
interface FastEthernet0/1
description *****Link To 6509C (Port 1/42)*****
switchport trunk encapsulation dot1q
switchport mode trunk
switchport voice vlan 100
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0
mls qos trust device cisco-phone
mls qos trust cos
auto qos voip cisco-phone
spanning-tree portfast trunk
!
interface FastEthernet0/24
description *****Link to Switch in DR Room*****
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0
queue-set 2
mls qos trust cos
auto qos voip trust
I don't have VLAN 800 setup on our switch and I was wondering if anyone could help me configure routing between VLAN100 and VLAN800 so the phone will register with Call Manager.
I hope I have enough info in here.
Thanks
Anthony

ok i will give a brief background regaeding ur case
if u have multiple voice vlans
and here in ur case 100 and 800
lets say site one users use voice vlan as 100
and ur callmanager is in site1 in vlan 100 too
remote site use vlan 800 as voice vlan
what u need to do is just enble routeing between those two vlans in other words make the bother vlans reachable between each other
and the helper address need to point to callmanager or any dhcp server or IOS dhcp server but the dhcp server need to have address space for that vlan
the only thing u need is the TFTP for ciscp IP phones if the TFTP is the same to callmanager which is mostly the case then
u need to creat a dhcp pool for vlan 100 les say on the call manager and put the call manager ip as the tftp server
on the remote site lets say on the L3 switch u created a DHCP pool for vlan 800 give then ip pool in that vlan rnage or u can creat a pool with vlan 800 rnage on the callmanager on the L3 switch interface for vlan 800 make the helper address as the callmanger ip
and tftp should be the callmanager ip as well
if u used the cisco switch IOS dhcp server serivce u just need to put the callmanager IP in the dhcp otipn 150 for TFTP
and all the above need routing communication between those vlans i mean 100 and 800
good luck

In your switch, can you verify that vlan 800 exist. You can do that by issuing a sh spanning vlan 800.
If it not there, create it.
Now, if you want to do routing with the 6509c, you need to create a vlan interface for vlan 800. You can base your config on the one you've got for vlan 100. It should work if you dont have any ACL in the way(but from a security standpoint, I hope you do...)

Hi,
Output from the spanning command:
DRSANTRYSWITCH1#sh spanning vlan 800
Spanning tree instance(s) for vlan 800 does not exist.
DRSANTRYSWITCH1#
VLAN100 is created on the 6509C like this:
interface Vlan100
ip address 10.100.1.5 255.255.0.0
ip pim sparse-dense-mode
standby 4 ip 10.100.1.4
standby 4 timers 1 3
standby 4 priority 10
standby 4 preempt
If I add the following to the 6509C:
interface Vlan800
ip address 10.1.180.1 255.255.0.0
ip pim sparse-dense-mode
standby 4 ip 10.1.180.1
standby 4 timers 1 3
standby 4 priority 10
standby 4 preempt
What do I need to add to the switch to get the phone to register with the Call Manager?
Thanks

first create the vlan on the switch:
conf t
vlan 800
after that, if you do a sh int f*/* trunk, you should se that your vlan forwarded on the trunk.
Since you dont have any ip helper configure on your vlan 100 interface, I guest that the Call manager is in the same vlan as the phone. You need to configure a ip helper adress on your vlan 800 interface to relay dhcp message to your dhcp server.
You will need to configure your DHCP(probably on your call manager server)

Hi,
Here is what I have done so far:
On 6509C
interface Vlan100
ip address 10.100.1.5 255.255.0.0
ip pim sparse-dense-mode
standby 4 ip 10.100.1.4
standby 4 timers 1 3
standby 4 priority 10
standby 4 preempt
!
interface Vlan800
description DR SANTRY VOICE VLAN
ip address 10.180.1.1 255.255.0.0
ip pim sparse-dense-mode

Where do I put the helper address, is the helper address the ip address of the call manager, the ip address of vlan 100 (voice vlan)?
