2901 with EHWIC-D-8ESG-P 8 port card, phones do not get to voice vlan

getdan · ‎01-12-2012

I have a 2901 router with a EHWIC-D-8ESG-P card in it. I have configured a DHCP Pool for the voice vlan but the phones get an IP address from the data vlan. What am I doing wrong..,?

ip dhcp excluded-address 10.2.100.1 10.2.100.30

!

ip dhcp pool Phones

network 10.2.100.0 255.255.255.0

Hi,

You have to configure these ports the old fashioned way.

If you want your phones to support both a VOICE VLAN ana
DATA VLAN try this

!
!
!
interface range giga 0/3/0 - 7
desc *** PORTS FOR PHONES & DATA ***
Switchport trunk encapsulation dot1q
Switchport mode trunk
Switchport trunk native vlan 1
Switchport voice vlan 100
Spanning-tree portfast trunk

no ip address

no shut

!

Give it a try

Alex

Hi Paolo

I have been thinking about this again

I am not sure if he has to create the

VLANS under the vlan.dat aswell.

!

vlan data

vtp trans

vlan 100 name VOICE

vlan 1 name DATA

exit

!

Just in case it is needed
