I have one switch 3750G12S

I joined the company new,

I found that they want to replace it with Alcatel stack switches.

I didnt configure this Cisco switch before.

I need some help on how to configure it.

I have 4 other new cisco switches in the topology which is not created yet.

the 4 switches are all 2960.

Need some help please.

Wafaa you are very welcome however it is much better for everyone especially you to post your questions here this way you not only have a single resource but multiple resources to help you out and suggest best practices , does that makes sense?

Feel free to ask any questions you have we all would be happy to help.

Thanks Mohamed for Replying, Thanks Joseph too,

I had configued the switch as L3

and made two vlans 100 and 200, first for data, second for voice, but I didnt

give an IP address for Vlan1... shall I leave it for management?

Then I connected 3750G-12S with 2960S with SFP through fiber...

The first Alcatel design was 3 switches stacked together and one of them connected to

packeteer to firewall to router.

Is it possible to do the same after configuring the core switch as L3.

or I will face problems.

One more question, why I cant connect to Cisco network Assistant,

is there any special configuration that I have to do.

Note: I have configured the first 4 ports for the 3750G-12S-S as trunk

so I can connect other switches as you and Joseph has suggested.

Note" I have Made Gi 1/0/12 as the port which will connect to the packeteer, but I dont know how i will configure it"

this is part of the configuration on the Alcatel switches that I have to replace them with the cisco ones

Can you share your switch config as a text file ?
