2960G stack to another 2960G

HI I have used all the ports on my 24 port 2960G and need to extend it with another 2960G. These switches do not have trunk ports so what is the best way to stack them and have all 5 vlans on both switches.

Can I just use a port Channel trunk  etherchannel ?

Thanks

Yes, you can use a L2 etherchannel trunk to allow the vlans to communicate across the switches.

Hi Brain,

Sorry for my previous post as I thought you are looking for 2960 S stack.
Please see the below example config and also see the below link for complete information for the same.


Configuring port channel in switch:

Switch# configure terminal
Switch(config)# interface range gigabitethernet0/1 -2
Switch(config-if-range)# switchport mode access
Switch(config-if-range)# switchport access vlan 10
Switch(config-if-range)# channel-group 5 mode desirable non-silent


Assigning port channel to an interface:

Switch# configure terminal
Switch(config)# interface range gigabitethernet0/1 -2
Switch(config-if-range)# switchport mode access
Switch(config-if-range)# switchport access vlan 10
Switch(config-if-range)# channel-group 5 mode active
Switch(config-if-range)# end

Hi Brian,

There are seperate Flex stack connection which you need to use to connect those two switches.
See the below link will help you completely.

Isn't that just for the 2960S switches ?

Jon

@ jon

you are right, the stacking moduls are only available for the 2960-s series.

@ brian

like jon mentioned, use etherchannel to increase the bandwith between the two switches and trunking.

for management purposes you could also use VTP, which also requires trunking.

Thank you all for the replies --

I am going to try to use trunking and vtp --

Is there any config example doc links for this config ?

Hi Brain,

Use the below link for VTP configuration.
Make one switch as VTP server and another one is as VTP client.
