Cannot add a port to a VLAN with number over 99

swakelen · ‎08-23-2005

We have a 6500 switch with dual Sup1A running 7.6(2). When we try to add a port to any VLAN with a number higher than 99 we get the following message

"VLAN number must be in the range 1..1005,1025..4094"

The VLAN is configured and active. This also appiles when trying to add a port to a currently working VLAN.

We are planning a reload (switch has been up for 171 days so far), unless anybody knows of any reason why this is not working? I have not found any relevant entries in the bug listing for this version of CatOS.

Any help greatly appreciated.

seems weird. switch is not a vtp client is it? I know that's not what one would expect for an error message but the fact that you can't even change a current port is weird as well.

Can you paste output of sh vlan?

swakelen · ‎08-23-2005

Yes this is weird, especially as it was ok. Switch is a VTP server, and we have had no problems configuring ports and VLANs in the past. It is also not possible to create a VLAN with a number over 99.

Here is some output.

RBS01-SW65-010 (enable) sh vlan

How about this? If you try to set up a vlan say 2 digits.. Use 40 for example. Does it work? Does it create a vlan 40 or 400? Looks like there is an extra character maybe not being displayed or something. I am grasping here but that would potentially cause the issue right?

Maybe try it from another machine or other terminal program to see if that works instead.

Obviously the commands look fine.

Let me know if you get anywhere.

swakelen · ‎08-23-2005

A good theory. I'll give it a try when I next get chance to log on and let you know.

I have now been able to try adding another vlan. I created vlan50, and it did create a vlan50 and not a vlan500. We have a scheduled reload occurring at 5am (BST) on the 25th, so unless I can find a reason and solution to this beforehand, we'll see what happens after then.

Well it was worth a shot anyway...
