How to configure Interfaces for Cisco 3850 Level 3 Switch using Sonicwall and Voice 2610XM

[bruce]

Hi,

We just recently upgraded our Cisco switches to Cisco 3850 Switches. However, we have an old voice gateway that I'm having a hard time figuring out how to configure to an interface port on the 3850 switch.

The configuration that I'm looking to apply is as follows:

Sonicwall X0 LAN

192.168.1.254

VoiceGW

192.168.110.254

CallManager

192.168.110.2

Cisco 3850

192.168.1.250

Data Vlan 102

ip address 192.168.102.1 255.255.255.0

Voice Vlan 110

ip address 192.168.110.1 255.255.255.0

vlan 1 (default)

192.168.1.1 255.255.255.0

vlan 102 (Data)

192.168.102.1 255.255.255.0

vlan 110 (Voice)

192.168.110.254 255.255.255.0

How do I configure the interface ports on the 3850 switch for the Sonicwall and Voice GW?

This is what I have:

Sonicwall X0 LAN (192.168.1.254)

interface gi1/0/2

no switchport

ip address 192.168.1.250 255.255.255.0 - (This line I'm not sure of)

no shutdown

Voice GW (192.168.110.254)

interface gi1/0/1

no switchport

ip address 192.168.1.250 255.255.255.0 - (This line I'm not sure of)

no shutdown

Configure default route to Sonicwall

ip route 0.0.0.0 0.0.0.0 192.168.1.254

Any thoughts or suggestions would be greatly appreciated!

Thanks,

Bruce

Hi

You can convert a port from layer 2 to layer 3, with the following ways you can connect other layer 3 devices to this port g1/1, example:

Method 1)

no vlan 10

no interface vlan 100
ip add 192.168.1.250 255.255.255.0
no shutdown

interface gi1/0/1
no switchport   <-- it converts to layer 3
ip address 192.168.1.250 255.255.255.0 
no shutdown

or the other method to use an IP + vlan:

Method 2)

vlan 100

interface vlan 100
ip add 192.168.1.250 255.255.255.0
no shutdown

interface g1/1
description <brief description to be used>
switchport      
switchport access vlan 100
switchport mdoe access 
no shutdown

* The interface will be working as layer 2 but associated to the IP 192.168.1.250,

And remember to enable the ip routing command globally to enable routing
