VLAN SETUP HELP????? 1

[captnops]

I am attempting to setup multiple vlans to seperate voice and data traffic using the following equipment:

Cisco 3560 switch
(4) Linksys SRW224P switches

Can someone provide a basic setup using the cisco as a layer 3 and the linksys as layer 2?

I have configured the cisco with IP routing enabled, created the vlans, gave the interfaces IP addresses, created a trunk port and connected to the linksys trunk port using dot1q encaps.

I cannot get traffic out of the the linksys to the 3560 to route to vlans.

Any help would be greatly appreciated.

it's like I said above

Now for every port EXCEPT your trunk port choose Untagged. Choose Tagged for your trunk port.

I have all ports set as untagged on the linksys. port 10 is a member of vlan 10, port 11 - vlan 11, port 12 vlan 12. A gig port is trunked, is a member of all vlans, and is tagged.

Still not sure what I am missing. This should not be splitting the atom right? Just to be clear:

I have created vlan 10, 11, 12 on the cisco (layer 3)each vlan having IP 10.1, 11.1, 12.1 addresses respectively.

I have created the same vlans on Linksys and made the linksys IP address 10.1.

Still no joy.

Is the port on the linksys hardcoded to 100/Full like it is on the 3560??

Dumb question...are you connecting the switches together with a straight-through or crossover cable?

Unclerico- I have hardcoded all interfaces to 100 full as cisco do not usually play well with auto neg.

Burt--Not a dumb question at all as it turns out the cable we were using was incorrect.

I was able to get this vlan'd network setup by doing the following:

On the Linksys, I set each port as access and untagged, then assigned each specific port to a specific vlan. The trunked ports were tagged dot1q and everything seems to be working ok.

As a consequence of getting this working, i have another question: I would like to apply QOS to our Toshiba VOIP voice traffic. The issue I am having is that the workstations are plugged into the IP phones and ride the same copper. I would like to address the IP phones in 1 vlan and the workstations in another. Any thoughts?

I greatly appreciate all the help and advice and the fact that you freely share these things. You folks really do make a huge difference.

 

[unclerico]

1) Both switches should support AutoMDIX so I didn't even think to ask that question.
2) The VoIP part might be a pain to configure with the Linksys' at the access layer as opposed to running Cisco or HP. You'll more than likely need to go to each phone and enter the VLAN information. The switch ports will need to be configured as trunks.

The problem with the cable was because the C3560 doesnt seem to support automdix.

I figured that I would have to configure each port as a trunk port and it turns out that Toshiba doesn't support vlans when the PC is hung off the phone, which is pretty stupid as that was always the promise of VOIP.

Thanks again

 

[unclerico]

no problem. the 3560 does support auto-mdix, but you just need to configure it under the interface with mdix auto...anyways, time to step up to a big boy VoIP solution lol (j/k of course)

I just saw the auto mdix command. Any way to apply it to all interfaces at once?

LOL, I would love a big boy VOIP solution (read that as Cisco??), but I am a technical call center and require a very capable ACD application and reporting.

 

[unclerico]

yep you can enter it like so (the spaces around the hyphen are required):

interface range f0/1 - 24
 mdix auto

I was able to find the command, thank you.

When adding the infrastructure to the default vlan for management purposes, do I also need to add any routers in the network to that vlan as well?

Yeah, that sounds very sucky.
Make sure your advice is correct - a lot of people selling this gear have zero idea of how it actually works.

The normal setup is you configure the edge switch ports as "trunks", but with the PC VLAN "untagged".
THEN - the phone itself needs to be configured on its "LAN" port to be "tagging" and on its PC port "untagged" on the PC VLAN.

I was told this by Toshiba using the IP cards that we are using. Newer (read as more expensive) cards do allow vlan tagging.... grrrrrrr!!!!

Thanks for the information. I thought that would be how it had to be configured, but no joy with my current setup.

I am attempting to add a vlan and place all my switches in it for the purposes of web or telnet switch management. I created the vlan and ip address, added the vlan to the trunk as tagged, but I am unable to access the switch. Any thoughts?

 

[captnops]

To make my statement above a little clearer; I want the ability to manage all of my switches from my desktop, independent of which vlan I am in? Does that make sense?

Thanks again

Is the 3560 acting as your collapsed core switch aggregating the Linksys'??

Re:
"I was told this by Toshiba using the IP cards that we are using. Newer (read as more expensive) cards do allow vlan tagging"

Does this information relate to the phones, or the IP cards in the PABX?

Because the IP cards in the PABX are irrelevant to the trunk config on the phones themselves - your PABX IP cards can just be on "untagged" access ports. They shouldn't even need to be in the same subnet/VLAN as the phones anyway.

I have no specific knowledge of Toshiba.

 

[captnops]

Unclerico: The 3560 is acting a the core distro switch aggregating the four linksys layer 2 switches.

Vince: The problem is that there does not appear to be anyway that the phone devices themselves can tag packets. And the workstations NIC cannot tag either.

I am still very interested in a solution that would seperate the voip traffic from data on the same port.

As a side note, I seemed to have solved the problem of managing the infrastructure from remote vlans. It appears that I inadvertantly set an IP address on the default vlan. Once I cleared that, I was able to manage the switches across vlans.

Thanks for all your help.
