Re: 5406zl how to downgrade firmware

If you did follow the instructions in the release notes when upgrading, yes you should be able to downgrade without any issues.

If you didn't upgrade or didn't follwo the instructsions you still can downgrade, however there might be some issues with the configuration you have.

 

But my question would be why do you want or see the need to downgrade? If you are running into issues with the code you are running it's advisable to contact HPN support and open a ticket so they can fix the issue rather then you downgrading.

Re: 5406zl how to downgrade firmware

Hi Mik

we upgrade from

 

Software revision  : K.14.34

ROM Version        : K.12.20

 

to the last maintenance release

 

Software revision  : K.15.04.0012m

ROM Version        : K.15.28

 

we followed the release notes, and prerequisites, and it was ok

 

But NOW it seem there are problems with SNMP v1/2 !!!

 

 

I never downgrade a firmware on hp5406zl.

The procedure ifor downgrade is the same as upgradind the firmware ?

If the boot-rom version changes too , it will be downgraded like the firmware ?

Re: 5406zl how to downgrade firmware

Then a downgrade is no problem, the boot ROM will remain the same as it is now since it's backwards compatible.

Just make sure you save your config before downgrading (just as safety precaution).

The same procedure is used for a downgrade.

 

Sorry, I can't assist on the technical part regarding the SNMP issue, for that you need to contact HPN support.

Re: 5406zl how to downgrade firmware

last question, excuse me

 

downgrade will be possible too if we pass from actual K.15.04.0012m  to  K.15.04.0009m and not back to the

old K.14.34  from which we start the process ?

 

 

thanks

Francesco

Hi Francesco

 

Yes, you can downgrade to 0009m.

 

What problems do you see with SNMP and 12m?

Re: 5406zl how to downgrade firmware

hi Arimo

we decided to upgrade to K15-08-0007 early availability.

 

SNMP problems seem to be:

 

SNMP (PR_0000046906)

LLDP-MED (PR_0000018681)

 

with K15-08-0007 smnp seems to be ok

 

best egards
