Solved: How to add Vlan 4030 in cisco 2960 Series switch

Bikas Giri · ‎09-24-2011

Hi,

I have got a WS-C2960S-48TD-L catalyst switch and cisco 1841 router. I want to create a Vlan 4030 and 4035 in a switch and send it to cisco 1841. I got a 4030 and 4035 vlan id from my isp. The isp send the vlan 4030 and 4035 tag from the router. Now I want to create this vlan, trunk the same vlan to a switch port and resend it as a trunk to cisco router 1841 so that I can create 2 sub-interface with dot1q. I am being unable to create the vlan id 4030 and 4035. I have done as below but can't see the vlan through show vlan althouth it says it is creating vlan id 4030 and 4035 when configuring it as trunk. So, please verify the following code and write me a process of it one by one.

ISP port (link from the ISP router to my managable switch)

=======

int fa0/30

switchport trunk allowed vlan 4030, 4035

switchport mode trunk

My side port (Link to my cisco 1841 from my managable switch)

int fa0/31

switchport trunk allowed vlan 4030, 4035

switchport mode trunk

Router Port (My router interface)

interface FastEthernet0/1

description *****CONNECTED TO FIBER*****

no ip address

interface FastEthernet0/1.4030

encapsulation dot1Q 4030

ip address xxx.xxx.xxxr

interface FastEthernet0/1.4035

encapsulation dot1Q 4035

ip address xxx.xxx.xxx

Thank you in advance.

Hi Bikas Giri,

I have one WS-C2960-48TT-L with version 12.2(52)SE and as you can see if I try to configure vlan 4030 it is possible.

Can you upgrade the IOS to the version 12.2(52)SE with IOS image c2960-lanbasek9-mz.122-52.SE.bin?

At your service,

If you do a "sh vlan brief" do you see these vlans ?

Is your switch in VTP transparent mode because it needs to be to create vlans in that range.

Hi,

Yes I have done sho vlan brief but could not see the vlan 4030 and 4035. I have also configured other vlans in this but below 1000. It's a running well with others. I don't think the VTP mode is set to transparent, if I set it as transparent mode will it effect to other vlan or not. Can I issue this command confidently ?

Hi,

changing to vtp transparent won't have no effect on the VLANS and it's the only to configure an extended range VLAN.

Regards.

Hello Alain and Bikas,

Before reconfiguring the switch into VTP Transparent mode, please verify using the show vtp status if the VTP Pruning is deactivated. If it is active, deactivate it using the no vtp pruning command before modifying the switch VTP mode. Moving a switch into VTP Transparent mode with VTP Pruning activated could result in all VLANs being pruned off the trunks leading to the newly transparent switch and breaking the network connectivity.

Best regards,

Peter

Hi Alain/Peter,

I switched vtp mode status to transparent. The show vtp status gives the result as follows.

Switch#show vtp status

VTP Version : 2

Configuration Revision : 0

Maximum VLANs supported locally : 255

Number of existing VLANs : 6

VTP Operating Mode : Transparent

VTP Domain Name :

VTP Pruning Mode : Disabled

VTP V2 Mode : Disabled

VTP Traps Generation : Disabled

MD5 digest : 0x7D 0x5A 0xA6 0x0E 0x9A 0x72 0xA0 0x3A

Configuration last modified by 0.0.0.0 at 0-0-00 00:00:00

But, till now also I am not being able to set vlan 4030 and 4035. When I tried to add vlan 4030 it gives result as,

Switch(config)#vlan ?

<1-1005> ISL VLAN IDs 1-1005

Switch(config)#vlan 4030

^

% Invalid input detected at '^' marker.

What wrong did I do ? What should I do now to add vlan 4030 ? Is there another command to add this vlan.

With best regards,

Bikas

Hi Bikas,

Looks like you are running a Standard Image on the switch. For support of vlans 1 through 4094, you need to upgrade to an Enhanced Image.

Kapil

Peter Paluch · ‎09-24-2011

Kapil,

To my best knowledge, there are no Standard/Enhanced images for 2960 series. There are LAN Lite and LAN Base - you probably mean the LAN Base?

Bikas, can you post the complete output of the show version command here?

Best regards,

Peter

kapathak · ‎09-24-2011

Hi Peter,

My bad! You are right, Enhanced Image is now Lanbase while Standard Image is now Lanlite!

Regards,

Kapil

Bikas Giri · ‎09-24-2011

Hi all,

The image is lanbase, I will paste the sho version after few hours.

With best regards,

Bikas

kapathak · ‎09-24-2011

Hi Bikas,

This is interesting. What is the IOS version being used? AFAIK, support for 4096 VLAN IDs is there on 2960 switches with LANBase since 12.2(25)FX

Can you post the exact image name or the complete show version?

Peter Paluch · ‎09-24-2011

Bikas,

In your first post, you wrote that the switch is WS-C2960S-48TD-L. The output of the switch you have posted right now is from a different switch.

Peter

Dear Peter,

Sorry I pasted the above information from packet tracer. I will paste the correct one after an hour.
