trunk port disables all vlans in switch

[siddindia]

Dear Sir,

i'm working with 2 cisco 3750 G series switches.testing bed is as follows:-

1) 2 different VLANs are working in both switch.

2) Trunk port is enabled.

3)2 vlans are working fine in each switch and communicating to each other well.

4) When i connect trunk port through a crossover cable,all ports of one swtch( which configured as vtp client)go DOWN and it never UP.

Again i have to reset switch and configure.

I have two questions:-

1) Why all ports go down when i connect crossover cable in trunk ports in both switches.

2) Is it necessary to configure one switch as a vtp client and one as a server.

a)If i will use both switches as vtp server, then what happened?

b)If i will not configured vtp domain SAME in both switches, then what happened.

Regards,

Siddhartha

Dear friend,

Thank you so much for your excellent response.

Actaully in my scenario, all VLANs musht be communicated with each other,Thats why i was using dynamic routing.

In your configuration, Is it possible that all VLANs will communcate with other.If Not, what should i do for that in your configuration?

In your configuration scenario, what will actually happen between VLANs?

REgards,

Good morning! Siddhartha

In my configuration scenario, I'm clearly sure that all VLANs will be communicated with each other without a dynamic routing.

If you want to use the dynamic routing,

Trunk configurations don't need anymore.

However several another configuration need in the SW1 and SW2.

Have a good day!
