LAN Base Switch Compatibility with Existing 3550Core Switch Environment

Dear Techie,

We are planning to buy a new switch but i was wondering if LAN Base switch will work smoothly and there will be no compatibility issue in relates to VLAN and other standard outcomes with our Core Switch 3550 Envionment.

You will need IP based L3 switches.

L3 can be LAN based also. LAN based L3 switches have IOS that does not support routing protocols (only static routing). Good news is the IOS can be changed to IP Based to accommodate that transition. This is not an option in L2 switches though as they are stuck in LAN base mode.

Hello Akins,

Thanks for your suggestion but if we dont want to use any routing protocol and its just all is static routing.

If we buy 2960X-24TS-L
Will it be fit for network ?

You need L3 switch to keep your SVIs and VLAN structure.
There must be routes between VLANs
L2 only supports 1 active SVI at a time.
L3 supports multiple SVIs and I presume you have multiple

The alternative is to configure your VLANs and routes on a router and use in conjuction with L2 but you'll lose the speed advantage (ASIC) that L3 switches offer
I already have a L3 Switch ie 3550.

I just want to use this switch as an additional switch.

You can have limited L3 with C2960S - static routes and with C2960-XR. But for proper VLAN routing, use L3 switch, like C3560-X or higher.
I already have existing L3 Switch i.e. 3550.

Yes, the proposed new 2960 will work smoothly with the 3550
They'll be fine.  Just remember that the 2960 uses SFP transceivers, not GBICs like your 3550 does.
Still we have not received the switch, i will  confirm the answer after we receive the switch
