Route data from vlan 10 to vlan 20 on 2960s

[David Kondicz]

Hello all,

i need to solves this little problem on 2960S lan BASE but i dont know if it is possible.

Uplink port config for gi 1/0/28 is:

switchport mode trunk

switchport trunk alloved vlan 10,11

but on interface gi 1/0/1 i want to have data from vlan 10 tagged as VLAN 20.

At this time i have solved this issue very primitively

I have set up gi 1/0/2 as int mode acces, acces vlan 20

and i have connected gi 1/0/2 with gi 1/0/3 with eth cable.

int gi 1/0/3 is switchpor mode acces, switchport acces vlan 10

Thank you for any ideas,

BR

Hi,

You can just create 2 vlans with 2 SVs.

Then add port gi1/0/1 to vlan 20 and gi1/0/2 to vlan 10

Example

config t

vlan 10

vlan 20

inter vlan 10

ip address 172.16.1.0 255.255.255.0

inter vlan 20

ip address 172.16.2.0 255.255.255.0

inter gi1/0/1

switchport

switcport acc vlan 20

inter gi1/0/2

switchport

switcport acc vlan 10

Hello Dave,

I don't fully understand the question, but here goes..

You cannot change the vlan tag if you have specified the vlan-id. So your vlan 10 will always be tagged by the switches as vlan 10. Frames will be tagged on a trunk interface, and on the access port there is no tag as it is stripped off.

If you wanted to route data from subnet to different subnet (between vlan 10 and vlan 20) then you need a router to route or to create SVI's. Im not too sure if the 2960's have this capability of creating multiple vlan interfaces with IP addresses.

If this was the question, enable 'IP Routing' and follow Reza's steps above.

If you cant enable ip routing then you need a router or a multi-layer switch.

You can do router on a stick which will route between your vlans, examples are provided here:

The way to enable ip routing is this:

conf t

!

ip routing

Hope this helps

Hi,

Came across routing on 2960s last year.

The 2960 does support ip routing.

Only statc routing

Only a MAX of 16 routes

You must change the SDM template to "routing" to enable this

feature

Please see this section of the configuration guide.

For That you must have lan base lic

to See

WS-C2960S-24TS-S (If it is S at last it should be using lanbase lite lic)

WS-C2960S-24TS-L (If it is L at last it should be using lanbase LIC)

isco   Catalyst 2960 Series Switches cannot be upgraded from LAN  Lite to LAN   Base and cannot be downgraded from LAN Base to LAN Lite.

In other words, the feature set is fixed during manufacture.

Other Option is to Use L3 Device Like Router or Layer 3 Switch to enable Intervlan Routing.

UHHGGG... I think this is a licensing issue.   I am experiencing the same problem after following similar steps on my own brand new 2960 switch...  

"Show sdm prefer" suggests I am on the lanbase-routing template but with 0 routed interfaces.

SW-01#sh sdm prefer

The current template is "lanbase-routing" template.

The selected template optimizes the resources in

the switch to support this level of features for

0 routed interfaces and 255 VLANs.
