2900XL - No Vlans 1

[bobbyforhire]

Hello all, Working on my CCENT then my CCNA. I picked up a 2900XL series switch. After looking around on it I noticed that there is only 1 VLAN...And i can't make any more. Does anyone know where i might be able to hunt down an IOS for this guy SA6 maybe (I'm running SA3). This guy only has room for a 1.2MB IOS...I need my vlans!!!

This is a layer2 only switch.. The vlan interface you see is for the management of the switch.. You can create more VLANs in the database, however you cannot make anymore vlan interfaces..

Its two seperate things..

VLAN defined within the database creates the VLAN
VLAN interface applies Layer3 parameters to the VLAN..

You can create several VLANs in that switch, and make access ports for each one. Like Buckweet says, though, there is only one SVI.

If you get a valid image you can delete the current image and add the new one . I believe those old ones will only hold 1 at a time anyway . Verify if it is a really old 4 meg switch or a newer 8 meg switch before you get a newer image. a 4 meg image will not work on a 8 meg box. A show version will tell you if it is a 4 or 8 meg.

I couldn't even buy a new image....even if i wanted to

That is an old 4MB...

Bobby,
Why don't you try the Boson demo to play with VLANs until you can put enough money together for a couple of 2950's? By the way, you can usually find the regular 2950-24 for around $100 on eBay with shipping.

Other free options are:
GNS3

http://www.gns3.net

Tutorials from:

http://www.blindhog.net

Packet Tracer 5.0
Ask around in the Cisco cert forum.. Someone may be able to put a copy on FTP if you ask...

You only need a couple of SI 2950's..

Mac, The best way to learn is hands on. I really just wanted to segment my own network. I have a 2948G but it's running a nasty CATOS. I was just really looking forward to "chopping" up my own netowrk. As for GNS3 and all of the others i have tried there is always something missing from there IOS's...I mean one will have some commands but there might be something missing. I duno i guess i just need better hardware

 

[vipergg]

I love catos , what do you want to know ? To create a vlan it is simply "set vlan XX" where XX is the vlan number . To see it created , use "show vlan" . To set a port into a vlan its just " set vlan XX slot/port" . To see this just use show port.
For trunk links it is simply " set trunk slot/port <desirable,auto, or on> " . A 2948 will do anything you need to do on the layer 2 end , where it might be lacking is if you need to get into COS stuff and things like that , as far as creating vlans and the general stuff its a great switch.

 

[vipergg]

If you need a newer image than what you have for your 4 meg box just go here , its free for the picking .not sure what you can do with a newer image , never really added vlans on the old 4 meg boxes though I have to believe you can create them .

Viper - THANK YOU! I know it's a great switch, I mean i picked it up off the bay for cheap but it doesn't help on the journey to ccna

 

[vipergg]

No but there is still a lot of it out in the field you may end up working on .

 

[burtsbees]

I have a 2980G with CATOS that a customer gave to me because their old admin left, and nobody there knew CatOS. I think it's easier and more straight-forward than IOS myself. The 2980G had gig ethernet ports, too...
Just type
set ?

Bobby,
I know what you mean in regard to hands-on.. I am big on the lab thing myself.. You should try to supplement GNS3 with those things that your lab is missing.. Try combining it with IOSHunter..

http://www.vitaltech-group.com/IOSHunter.htm

It's pretty cool but the free version limits the IOS's that you can grab... Still, you can definitely find enough to successfully stock GNS3...

On the 2900XL you make the vlans by configuring vlan database directly.

Switch#vlan database
Switch(vlan)#vlan 10 name Sales
Switch(vlan)#vlan 20 name Marketing
Switch(vlan)#vlan 30 name Engineers
Switch(vlan)#apply
Switch(vlan)#exit
Switch#

The newer IOS configures vlans through global configuration.

HTH

 

[maczen]

I am pretty sure that you can make them either way on the 2950 but it is recommended to be done globally as the VLAN database command is being phased out.

[burtsbees]

Actually, you don't really need the database command---it's just for naming the vlans. You can always put in a description on the interface if you want to name the vlans. You can make all switchports access ports for different vlans, but there can only be one SVI. Whatever vlan you give an IP address to will be the management vlan---what you telnet/ssh to to remotely manage the switch.
I am not sure about the 4MB versions, viper knows more about that...

Ok first off Burt - Congrats on the Weekley Nerd award!

GN3 - I Tried it on my laptop (1.6ghz,1gb ram) and it just shut me down while running GN3. I have a few other PC's i can try it on and from the looks of it i need to do this.

Kinda off topic here but. I have a 2610,2611,720 router..none of witch can run the SDM Can you install SDM on a GN3 if so that will be more of a reason to jump to using it.

 

[burtsbees]

Weekly nerd...ha ha.
Your other option would be to just configure one that does support SDM, and copy that config to one that doesn't.
You can however use SDM in Dynamips/GNS3...here's how...

You can also download that SDM sales demo.. It does everything except apply the configurations... Perfect for study!
