Cat2900XL ^VLan^

[kyaw_thu]

I have one Cat2900XL with "flash:c2900XL-c3h2s-mz-120.5-XU.bin"...And I am wondering whether i can use that for creating VLans.

interface VLAN1

ip address 192.168.65.70 255.255.255.0

no ip directed-broadcast

no ip route-cache

!

interface VLAN4

ip address 192.168.1.1 255.255.255.0

no ip directed-broadcast

no ip route-cache

shutdown

C2900XL#show vlan brief

VLAN Name Status Ports

---- -------------------------------- --------- -------------------------------

1 default active Fa0/1, Fa0/2, Fa0/3, Fa0/4,

Fa0/5, Fa0/6, Fa0/7, Fa0/8,

Fa0/10, Fa0/11, Fa0/12

2 VLAN0002 active

4 VLAN0004 active Fa0/9

I created 2VLans. But I can't bring VLan4 into service. It always show "shutdown"..Even I put "no shut" also doesnt work..

From "show Vlan", it shows vlan4 is active..*sigh*

can anybody help?

Hello,

the 2900XL is not Layer 3 capable, so you cannot create VLAN interfaces on that switch (with the exception of the VLAN 1 interface, which is used only for management).

You can only assign the ports on the switch to VLANs, but the inter-VLAN routing needs to be done by a Layer 3 device, e.g. the 2948-L3, or the 3550 swicth, or a router.

HTH,

Georg

Is it possible to just upgrade the firmware on C2900XL in order to do the VLan ?

If yes, which ios should I upgrade to?

Hi,

you are mismatching two different things: "VLANx" and "interface VLANx".

You can create a new VLAN on Cat2900XL by CLI using foloowing steps:

enable

vlan database

vlan x name ....

exit

See http://www.cisco.com/univercd/cc/td/doc/product/lan/c2900xl/29_35wc6/scg/swvlan.htm#73213

You can also define an "int VLANx". This is a virtual interface used for switch management purposes only. You can assign an IP address to it.

You can even define another "int VLANy". But only one management interface can be active any time (int VLAN1 by default).

(There is no L3 functionality available on Cat2900XL switches.)

See http://www.cisco.com/univercd/cc/td/doc/product/lan/c2900xl/29_35wc6/scg/swvlan.htm#xtocid2 for more details.

Hi,

Basically what I want to do is ..I have one existing network which is 192.168.65.xx.

I want to have one seperate subnet. So I plug in C2900XL into existing network and assign 192.168.65.70.

My question now is how can i make Interface FastEthernet 0/9 to network 192.168.1.0? And that network should able to talk with 192.168.65.xx.

Hi,

simply create new VLANx as described above.

Then assign Fa0/9 into this VLANx using

conf t

int fa 0/9

switchport access vlan x

On the PC connected to fa0/9 configure an IP address 192.168.1.y

But if you need the 192.168.1.0 to communicate with 192.168.65.0 you need to involve some router. Cat2900XL is only L2 device.
