On a VG202 Gateway, can I use the 2nd FAst Ethernet port to connect a PC ? I would like to connect the VG202
to a LAN switch, and have a PC behind it on the second Fast Ethernet port. On an analog port, I will connect an analog Fax.
In fact, the VG202 will act a little bit as an IP Phone, with a PC connected to it.
On the first Fast Ethernet port I will have voice vlan + data vlan and on the second Fast Ethernet port to the PC, only the data vlan.
Please see the drawing attached.
Is this possible ?
Solved! Go to Solution.
I have used IRB and BVI interface sometimes, but I don't understand how do you want me to use it in my present case.
Normally on the uplink I will have 2 VLANs (voice for the Fax and Data for the PC) as we normally do
with an IP Phone.
will the VG202 be able to separate between voice trafic to the fax and data trafic to the PC ?
Thank you for a config sample or any additional information.
Please find an example of the VG202 configuration and as well the associated switch port where it was connected to (the switch was a 3550).
First Ethernet port was a trunk to the switch
The second Ethernet port was connected to a PC
One of the VG async port has an analog phone
Hope this will be helpful.
Did you look to the switch configuration I provided at the bottom of the small text file ?
Generally with an IP Phone and a PC, you configure your switch port with an access vlan and a voice vlan. Which is actually resulting in doing a trunk, even if not configured as a trunk.
In the switch configuration I provided, this is exactly the same : you have a data vlan and a voice vlan. And you use only one switch port. What is disturbing you in this configuration ?
But the answer is "no". We made a lot of tests before going to this trunk configuration, and it appears to me that you can't configure it as it is with an IP Phone. You have to use a 802.1Q trunk. So you should have a specific configuration for a port with a VG202, different than for an IP Phone.
Hello Marc, it is a environment w/ 300.000 Users. The User can order a LAN Port Voice Ready, but not a Trunk Port. We offer 3 Types of LAN Ports to the customer but no Trunk Port. For example to make a Upgrade at CUCM, this Project takes near one Year, we must concider a lot of things and each Bug etc... etc.....
So, in this environment to offer a LAN Port as an Trunk, it is the same like Porsche develope a new Car :-).
DHcp is configured for the VG on subinterface FastEthernet0/0.1 with the command "ip address dhcp".
Fo the PC, this is up to what is configured on the PC IP Stack.
As far as the PC port (int. FastEthernet0/1) and uplink data vlan (int. FastEthernet0/0.2) are bridged together, dhcp messages will be forwarded transparently to the switch.
