Hi. I have kind of a design question on voice and data vlan routing. Equipment involved:
Router: Cisco 2811 for CME, two Fastethernet ports and NME module
Switch1: Cisco Catalyst 3750G-12S-S SMI 12 port Fiber with with sfp modules
Switch2: Cisco Catalyst 2960G-24TC with 2 gigabit sfp modules
Switch3: Cisco Catalyst 2960-24PC-L with one Gigabit SFP module
Other switches: 11 WS-C2960-8TC-L each with one gigabit sfp module
Connecting both Fastethernet ports on CME router to Switch2 Fastethenet ports
Connecting core switches together via
Switch SFP ports
11 Remote switches connecting via fiber to 12 port fiber switch
The functionality I need for voice and data vlans on all switches is to be able to plug in a PC or Cisco Phone into any ethernet port on any switch and receive either dhcp address for data or ip address and phone load for voice. The pc's will not be haging off a phone.
The voice router will not be connecting to the Internet. The Internet link will be an ASA 5505 on the data vlan.
I need a little help setting up the vlans for this functionality. I know I can do something like this on the switches:
interface Vlan10
ip address 192.168.10.23 255.255.255.0
ip helper-address 192.168.10.5
no ip route-cache
!
interface Vlan20
ip address 192.168.1.23 255.255.255.0
ip helper-address 192.168.1.15
no ip route-cache
interface GigabitEthernet0/1
switchport access vlan 10
switchport mode access
switchport voice vlan 10
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0
queue-set 2
priority-queue out
mls qos trust device cisco-phone
mls qos trust cos
auto qos voip trust
spanning-tree portfast
(fiber port):
interface GigabitEthernet0/21
switchport access vlan 20
switchport trunk native vlan 20
switchport trunk allowed vlan 10,20
switchport mode access
switchport voice vlan 10
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0
queue-set 2
priority-queue out
mls qos trust cos
auto qos voip trust
spanning-tree portfast
with router Addressing as follows:
interface FastEthernet0/0
ip address 192.168.10.5 255.255.255.0
duplex auto
speed auto
!
interface FastEthernet0/1
ip address 192.168.1.2 255.255.255.0
duplex auto
speed auto
!
interface Integrated-Service-Engine1/0
description Panoche Unity Express
ip unnumbered FastEthernet0/0
service-module ip address 192.168.10.1 255.255.255.0
service-module ip default-gateway 192.168.10.5
no keepalive
ip route 192.168.10.1 255.255.255.255 Integrated-Service-Engine1/0
!
But it is not working as I thought and the PC's cant ping all switches and some switches cant ping both router ip addresses, but all switches can ping the vlan ip addresses on switches.
I'm probably missing something simple, and could use some insight. I can post more detailed configs later, but this is the gist of it.
Any advice would be appreciated, I don't get to do this type of config often and am pretty rusty. Thanks in advance
