MSTP pending instance configuration

Hi,

I have 2 procurves 2848 and i want to reconfigure the mstp. I created pending configuration with 5 instances. I odd vlans to each instance, but when use the command "show spanning-tree pending mst-config" i see the created instances but no vlans are showed in the "Mapped Vlans" column.

This is a bug or i'm doing something wrong?
The commands i used to create de pending spanning tree configuration was:

spanning-tree pending config-name XXX
spanning-tree pending config-revision 1
spanning-tree pending instance 1 vlan 1-4

Thks,

Re: MSTP pending instance configuration

Hi,

I don't have a spare 2848 to test with but the MSTP pending commands work fine on my 2610 (running revision R.11.30).
What do you see if you run:

"show span pending inst ist"

Re: MSTP pending instance configuration

The command "sh spanning pending instance ist" return no additional information.

No vlan associated with the "Mapped Vlans" columns.

Re: MSTP pending instance configuration

But are the VLANs you are looking for associcated with the IST?

Oh and what software revision are you running?

Re: MSTP pending instance configuration

The firmware revision is I.08.98 and the ROM version is I.08.07.

I Know, i know ... they need to be updated, but I take a look at the most recently software update release notes and didn't find any enhancements or fixes related to this issue.

Re: MSTP pending instance configuration

Well you're not doing anything wrong so it does sound like a bug.
The question is whether the bug is just with the "show" command or whether the vlans aren't being assigned to the pending configuration at all.
The only other command you can try to test is : "show span pending inst 1" and see if they're listed there.

Re: MSTP pending instance configuration

Hi Bruno

I would suggest you go and look at the latest software from HP ProCurve.

In I.10.65 Enhancement (PR_0000001316) â The VLAN Assignment mapping to MSTP instances
is enhanced.

and

â   VLAN (PR_0000002103) â The alteration of the VLAN/MSTP instance mapping in the
pending configuration is not properly functioning. Any attempt to remove a single VLAN ID
(VID) from one MSTP instance and then assign it to another MSTP instance will fail, even
while specifying a VID range will succeed.
