New Nortel 450 user

[nadeemz]

Hello all,

totally new to VLANs and Nortel 450. trying to set up a VlAN. a very basic one. have two laptops connected to the Nortel just to test. one on port 1 and the other on port 7. laptop on port 1 has an IP address of 192.168.226.. range on VLAN 1 and lap top on port 7 has an IP range of 192.168.104.. on VLAN 1. should i be able to see the two laptops? thats all i want to achieve for the time being. i have setup two VLANs from the CLI but i can not get the lap tops to see one another.

can anyone help please?

thanks

Is this a new 450? If the settings are default then yes you should be able to talk between them. You could try defaulting the 450 to eliminate any legacy programing that might be causing problems.

Good luck,

hi,

this is an old 450, software version 1.3.2 and Firmware 1.36.

have tried the default settings but still can not see either lap top.....

doing my head in.

Check your VLAN settings. The ports should be in the same VLAN and have the same PVID. Assuming the values are default these should both be 1.

What about the network settings on your laptops? If you assign an IP to the 450 can both laptops ping it? Can the 450 ping them?

Does this happen no matter which ports it is plugged into?

Worst case, I believe these have a lifetime warranty and you could call it in for replacement if you have some bad ports.

im going to try it. lets hope it works. i can ping the Switch from the lap top which is on the 192.168.226 range, that is what the switch is. i can not ping the switch with the lap top on the 104 range.

do the lap tops have to have the same default gateway? at the moment i have entered the firewall for each subnet as the gateway, do i need to make the gateway the same as the Nortel switches IP address?

thanks

Oh, I thought these were on the same subnet. The problem is probably your subnet masking. I assume you are using class C masks on both laptops and on the switch. In order for both laptops to be able to talk to the switch you can change the switch mask to a class B. The laptops won't be able to talk to each other because they recognize they are on separate subnets and are routing to their default gateway. The only way to make these laptops talk would be to convert their subnet masks to class B also. Keep in mind though that this would make one subnet where you have two.

What exactly are you trying to do with this 450?

Ok,

Thanks again, this is the issue. We have two sites here. 192.168.104… subnet of 255.255.255.0 gateway 192.168.104.2 and the second site 192.168.226…. subnet of 255.255.255.0. gateway 192.168.226.190. We share resources from each network via a VPN at present. We want to remove the VPN and allow both subnets to talk to each other via the Nortel VLANs. The Nortel 450 has the ip address of 192.168.226.230 and the subnet of 255.255.255.0. Gateway 192.168.226.207.

The 104 range is running out of hosts, we have reached 250. The 226 range still have 150 available internal ip address’s for us to use. We want to utilize that instead of changing the 104 range into one new range such as 105 etc.

Does that make sense? Sorry if it doesn’t. My work with VLANs and Nortels is quite basic so am just trying to get a better understanding myself.

Thanks

The 450 switch can't route.. If you get a Baystack 5510/5520 this support route VLAN.

I agree. This won't work with a 450 because it is strictly a layer 2 switch. You will need to install either a layer 3 capable swith or a router of some kind.

Good Luck,
