3750x Stack and VLANs config

[maksimu521]

I have 2 new 3750X - 48-S in the stack. I need 3 non-routed VLANs for my virtual environment ( Cos/Management, Vmoton/HA and ISCSI) and 2 access VLANs ( I have 2 existing networks 192.x.x.x and 172.x.x.x). I have 4 hosts and each of them has 8 NICs available. So COS, VMotion/HA and ISCSI will have a dedicated connections, but for my access VLANS I have to use a tag for VLAN ( 2 networks on 1 physical connection). In addition I have to connect these switches to my old Nortel’s that has 192 and 172 networks for user's access. What is the best way to do that? I never deal with Cisco switches and I am totally overwhelmed with their terminology and I am lost. Please help it does not look like a complicated setup, I just need to know how to configure VLANs, assign ports or groups, etc.

Ports 1-13 - Vlan 1

Ports13-24  - Vlan 2

Ports 25 - 26 VLAn 3

Ports37 - 48 Vlan 4 ( tagged)

follow the config guide to creat your vlans

here is a sample for each vlan

http://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/release/12.2_55_se/configuration/guide/swvlan.html#wp1197558

Switch# configure terminal

Switch(config)# vlan 1

Switch(config-vlan)# name test1

Switch(config-vlan)# end
Switch(config)# interface gigabitethernet1/0/1 


Switch(config-if)# switchport mode access 


Switch(config-if)# switchport access vlan 1


Switch(config-if)# end 


 

Switch# configure terminal


Switch(config)# vlan 2



Switch(config-vlan)# name test2


Switch(config-vlan)# end
Switch(config)# interface gigabitethernet1/0/13

Switch(config-if)# switchport mode access 


Switch(config-if)# switchport access vlan 2



Switch(config-if)# end 



Switch# configure terminal



Switch(config)# vlan 3



Switch(config-vlan)# name test3

Switch(config-vlan)# end 
Switch(config)# interface gigabitethernet1/0/37

Switch(config-if)# switchport mode access 


Switch(config-if)# switchport access vlan 3


Switch(config-if)# end

Thank you for a reply. But how to do a tagged VLANs and the connections to my Nortel switches to avoid any loops?

[Reza Sharifi]

for that interface you need

switchport mode trunk

switchport trunk encapsulation dot1Q

You need to do the same on the Nortel side
