GBIC Trunking between 6505, 3550 and 2950

[kgohel]

I am trying to connect our new areas to our core 6505.

All the VLANs are already in place on the core switch.
All the equipment has been purchased.

This is what I need to do

1) Connect (2) 2950 GBIC ports to the 6506's msfc2 GBIC ports. Both 2950 need to connect to VLAN8.

2) Install a backup msfc2 module on the 6506 and then connect a 3550's GBIC to backup msfc2's GBIC. The 3550 needs to connect to VLAN2.

My questions are:

- On 2950 and 3550: Do I have to set all the ports (48 FastEthernet and 2 GigabitEthernet ports on VLAN8 or they can stay on VLAN1 (default)? Where do I configure Ip address? VLAN1 or VLAN2 and VLAN8?

- on 6505,2950, 3550: what VLAN trunks should belong to? VLAN1?

- On 2950 and 3550: Do I put all the non trunk ports in the whatever VLAN and keep the trunk in VLAN1?

I am a little confused as how I will do this.

Thanks in advance for any reply.

if you setup vtp on the core switch, probably already set then make sure that you turn on the the vtp domain in the 3550 switches

vtp client (make sure you do this before connecting the switches)
vtp domain DOMAINNAME


interface xxxxxxxxxxxxxx(interface that will connect to 6500

switchport mode trunk
switchport native vlan xxxx

to find out the native vlan use

show cdp ne de

this will tell you the native vlan on the 6500

you can also use

show interface switchport

on the 6500 ( this is an ios command so if its cos i am not sure what the command is)

vlan 1 is nice to use for the management vlan

on the client switches once the trunks are setup use the following to set the vlans on each port


interface xxxxx
switchport mode accese (if its never going to be a trunk)

switchport access vlan xxxx( use the vlan number you want it to access)

switchport host (this will disable etherchannel negotiations, dynamic trunking and enable spanning tree so that the port comes up faster)

to set the management interface on these switches you will need to configure the proper vlan interface with an ip address

ip default-gateway x.x.x.x ( not necessary unless proxy arp is disabled on the gateway interface)
interface vlan xxxx
ip address x.x.x.x x.x.x.x
no shut

hope this helps
