One one of my switches, the vlan's are down. How do I configure them to make them stay up and what does it mean when they go up and down?

Regards,
Dj
 
i don't know what switch model you are running, but make sure that:
1) the vlan(s) is not administratively shutdown
2) each vlan has some access ports as members

I hate all Uppercase... I don't want my groups to seem angry at me all the time! =)

cisco 3750's. Yes they have many ports assigned. What does administratively down mean vs just down? It goes up and down. I'll have to reseach the commands to see if it is administratively down, but I don't thank that's the case. I'll let you know once I get a chance to look it up.

type (show ip int brief) on the switch.
Verify the output. Also look at the vlan it self
(show vlan 1) or whatever the vlan is.

Did you install another switch into your network. Is the switch setup as a server for VTP. (Show vtp status).

administratively down means the interface has the shutdown command configured.
 
also, remember to go into config t mode and do <vlan #> to create the VLAN in the vlan.dat file. doing int vlan # should do it, but I have seen it not bring up the vlan until i did the vlan # command.

Administratively they are all up.
And yes they are up now, but they go up and down. Is this normal? Sorry for the confusion.

Regards,
Ison67
 
Going up and down is not normal. Have you verified power to your equipment. Have you cleared your router as being the source of the problem?

Is this switch by chance stacked with anything else? If so, do you have an extra StackWise cable?

/
 
Ok, It's been crazy around here.
I sent you bad info. Info from the router, not the switch that's having the problems. Let's try this again.

Sorry and thanks,

do this...

conf t
int vlan 2
no shut
int vlan 3
no shut
int vlan 4
no shut


that will bring them all up... they are in shut down mode.

Thanks, or that was easy enough. But when I when to copy it to the start-config, I get this.

do wr mem and see what you get


also post a sh flash

Got it! I was working on stomething else and lost my connection. Logged back in and try again, wr mem. It worked.

I tryed the same thing, config t, int F0/14, no shut, with some of the ports that keep going down, but it didn't work. Am I doing something wrong? Does it work on ports?

Regards,
ison67
 
Unless the ports are "admin" down doing a no shut has no effect . I don't see any ports in a admin down state.
 
Thank you! You have been a great help.

Regards,
Ison67
 
I noticed this on another which and went in an changed it for vlan 2. I loss the connection and now I can't ping it. After some research, I learned that the switch is a c2950/level 2 switch and can have only one vlan admin up at a time. How do I get back it in?

ison67
