I have a 3550 switch a number of VLANS, 2 to 5 to be exact. I need VLAN 5 to extend over to the 2950.
Would simply trunking the 2 switches solve this, by using dot1q trunk on a port on each switch?
The complicated part comes when I then have to give VLAN 2 on the 3550 (servers) access to VLAN 6 (servers) on the 2950.
One switch is L2 and the other L3, so I'm not sure if the L3 switch (3550) can provide the InterVLAN info or not.
Anyway let me know what you think?
Make sure you have all the VLANs created in the 2950(if you are not using VTP server/client mode but using transparent mode) and configure the interfaces to be dot1q trunks.
Yes, your 3550 can do intervlan routing and you can configure Access-lists to filter traffic as well.
Following tech tip should help as well
trunking two switches together will work.
To provide intervlan routing configure two VLAN interfaces on the 3550 with IP addresses corresponding to each VLAN. That will do it.
Shouldnt be an issue.
Setup VTP and make the 3550 the "Server" and the 2950 the "Client"
You'll just have to config VLANs on the 3550 and they'll be propogated to the 2950.
As you said, you will need a "trunk" link between the 2.
Trunk links are made to carry multiple VLANs versus and "access" link which is made to carry just 1 VLAN.
Just set the default route on the 2950 to the 3550 and life will be good.
You would also need to make sure taht the VTP domain name is the same on both switches in this case.
To avoid possible problems set the domain name on 3550 first. Then set the name on the 2950 to something random and then back to the domain name you will use (if you go down VTP route). This will start the VTP revision number on the 2950 from 0 and thus prevent it from possibly messing yiur VLANs up on the 3550.
I would not use VTP in a simle set up like this though.
VTP help u tp extend vlans over group of switches u need to have the main switch as the VTP server and others client
the switch in VTP client mode and in the same domain to a switch in vtp server mode
the client will pull vlans from the server one and u only need to assigne these vlans to ports on the client switch
if u have the 3550 as VTP server and a group of switches connected to that switch and they are in client mode u only ned to creat the L2 vlan on the 3550 switch and the vlans will be pull from those switches
it is time and efforts saving
VTP mode server
VTP mode client
VTP domain [domain name]
this name must be the same on all switches the clients and thier server to get it work
show VTP status

Thanks, do you know if the 2550 and 3550 support Auto-MDIX? As I think I might need a crossover for this trunk. I would of thought the 3550 supports Auto-MDIX.
IOS - c2950-i6q4l2-mz.121-22.EA12.bin
IOS - c3550-ipservices-mz.122-40.SE
it is as simple as the following
on the L2 switch make the link to the 3550 as trunk
on the 3550 do the following
cteat L2 and L3 vlan
interface vlan 2
ip address 18.104.22.168 255.255.255.0
interface vlan 6
ip address 22.214.171.124 255.255.255.0
then enable ip rputing
now on the hosts connected to 2950 and belong to vlan 2 thier defualt gateway must be vlan 2 interface like 126.96.36.199
and vlan 6 hosts 188.8.131.52
this way u will route between vlans
and u need the L2 vlan created on the 2950 as well like
good luck if helpful Rate
