I use 'J9643A HP 5412 ZL SWITCH WITH PREMIUM SOFTWARE' as main switch.

Normaly I use 28 vlans. Today I log into switch (ssh). Using menu interface I added new 8 vlans.
(New vlan id numbers 301 to 308. Previous 26 vlans use id numbers lower than 301, and last two use vlan id =999, 1000.)
 
Then I wanted to assign this new vlans to interfaces and went to (2. Switch Configuration... --> 7. VLAN Menu... --> 3. VLAN Port Assignment) and noticed lack of last two vlan's (id=999, 1000). I figured out that is because some limit in "menu" tool, so I decided to remove two or three of newly created vlans. I went to (2. Switch Configuration... --> 7. VLAN Menu... --> 2. VLAN Names ) select 301 vlan and choose [Delete] option.
This caused switch freeze and crash/reboot (at least I'm convinced that it freezes and it took long, long ~120seconds before start of reboot process.)

My switch has:  Version:   K.15.02.0005
After 'show tech' (attachment) and SwitchRelease Notes study I'm convinced such incidents was resolved since Version K.15.04.0002:

    * Crash (PR_0000055261)—In some situations the switch might reboot unexpectedly with a message similar to the following.
             SubSystem 0 went down: 06/22/10 09:24:00
             NMI event SW:IP=0x00e953d8 MSR:0x02029200 LR:0x00eb25c8
             cr: 0x24000400 sp:0x02e30aa8 xer:0x20000000
             Task='InetServer' Task ID=0xaad5000

 

I post, because maybe some find that information useful, but I also have some questions:

Is lack of some vlan's in menu interface (in 2. Switch Configuration... --> 7. VLAN Menu... --> 3. VLAN Port Assignment) that I described bug ? (Do anyone manage more than 28 vlans with menu interface?)

[... In some situations the switch might ...] what are these 'some situations' from Release Notes, and is it possible that my vlan changes in menu interface and reboot was unrelated?

Will command "no vlan ..." cause _exactly_ the same behavior as 'menu' tool? ( I would like prevent any reboots ).

 

Do vlans id=301 ... 308 are somehow reserved ?

 

What is Task='InetServer' responsible for ? (Is it responsible for www interface, so disabling www access might be temporary fix?)

Is there reason not to update to the newest (K.15.06.0006) as a long term solution?

I can't answer all of your questions, only a few of them:

 

The menu tool is a legacy management interface that is no longer expanded to include new features.  At the time it was created the limit on vlans was much lower than it is now.  It does not surprise me that it cannot manage that many vlans.  Your best option is to use the command line interface to manage your vlans, it will support as many vlans as the switch will support.

 

I just added, and then removed, 55 vlans to my 5400 (running a K.15.06 build), including vlans 301-310 and the switch functioned perfectly.  Vlans 301-308 are not reserved.

 

I recommend you update your software, you will then have the most current and supported version.

As soon as we upgraded to ver K.15.02.0005 our switches could not  find sntp server & log statements indicated this...We needed this upgrade for v2 cards...

Have you tried switching between sntp and timep (timesync sntp/timep)? What does the output of the "show sntp" command look like?

yes there is a bug in that version with the SNTP, you need to update to K.15.06.0008 which is posted on the website now

I didn't stay at this revision due to instability with 10Gig ports...

 

I've been running K.15.04.0007 now for ~ 89 days without any stability issues, however, I'm about to upgrade to K.15.06.0008 due to IGMP vs PIM mrouting issues.

 

On your vlan issue, how many vlan's do you have configured?

 

I have ~ 53 vlan's configured, however I only see ~ 32 in the menu...
