2924XL interface vlan - shutdown (can't open it)

[ase2dais]

Hey Gang!
got this 2924 w/ 5 vlans, I've assigned a ip of each vlan,
I can't telnet to the remaining 4 vlans. and it can't accept the "no shutdown" command for vlan 4-5. Vlan1 is up
and able to telnet to it.
and here's my sample of my config.

any help is appreciated.

<start>

!
interface VLAN6
ip address 131.107.6.50 255.255.255.0
no ip directed-broadcast
no ip route-cache
shutdown
interface VLAN3
ip address 131.107.3.50 255.255.255.0
no ip directed-broadcast
no ip route-cache
shutdown
!
interface VLAN4
ip address 131.107.4.50 255.255.255.0
no ip directed-broadcast
no ip route-cache
shutdown
!
interface VLAN5
ip directed-broadcast
no ip route-cache

<end>

Your switch is working correctly. Only one VLAN is allowed to be up at a time. This is known as the management VLAN. All other VLANs will remain in shutdown mode, unless you change one of them to be your management VLAN.

Inikis,

Tell me this then, was is the purpose of the default gateway in the management vlan?

My setup is that Vlan 1, Vlan3, and Vlan4, all has a 2500 series router in them, and those routers are serially connected to each other. This makes the devices on each vlans communicate to each other.

so, I am trying to figure what is the use of the Default gateway in the managment Vlan, when the devices are set up to default to the Cisco 2500, that is connected on the each vlans.

Can you explain ?

Sure I can explain.

When a Windows computer attempts to connect to something not local to its LAN, it sends the packets to its default gateway.

So if you were to ping FROM THE SWITCH to something not on the same LAN as the VLAN interface, it sends the packets to...its default gateway.

It becomes very useful when you are trying to telnet to your switch from the internet. The only way a switch is going to get packets back to you, is to send them to...its default gateway.

Also, just as a side note...

There are actually quite a few &quot;routing&quot; commands in the switch that server absolutely no purpose. This is because the switch's IOS is actually a router's IOS which has been scaled down and adapted for a switch. But not everything got removed....

okay Inikis, got your point. Let me quiz you here some more.

I am able to install jre 1-3-1 on my pc to we access the switch. the initial prompt for web login was successfull, since I have done a &quot;username admin privilege 15 password cisco&quot; on the cli.

But while on the switch textual web, I tried to click on,
&quot;Cluster Management Suite or Visual Switch Manager&quot;, and
the virtual manager came up, and it prompted me for a login name. I used the same admin acct
and password. I can't get in, and see what this virtual manager is suppose to do.

any hint, explanation or sermon ?

Hmm, believe it or not, this is a very common problem. Sometimes just using the enable password will work, with no username. Give that a try.

If you have CCO access to Cisco's website, they have a little document that runs you through a few things to fix your particular problem.

But try the enable password with/and without the username you specified in the config.
