Ethernet Routing Switch 5000 Software Release v6.1.6 – WARNING

In March 2011 Avaya released v6.1.6 software for the Ethernet Routing Switch 5000 series. Since that release there have been a number of posts on the discussion forums and one thread in particular where a number of members have discovered a particularly nasty bug in the 6.1.6 software release.

In summary if the switch will continually reboot with a data exception error after the upgrade to 6.1.6 if it was originally configured running 4.x or 5.x software. You can recover from the problem by performing a factory reset of the switch and re-configure it from factory defaults. If you have the ASCII backup I believe you can upload that configuration after factory resetting the switch as opposed to manually re-keying the entire configuration by hand.

If your switch was originally configured running 6.x software then you apparently won’t have any issue upgrading to 6.1.6 software.

I’m not sure how this missed the QA folks… but I’m sure it’s probably hitting the fan right now back at Avaya.

Thanks to telecom116 for bringing the original issue to our attention.

Cheers!

 

ERS 8600 Software 4.1.6.0 buggy

It would seem that Nortel has discovered some serious flaws in software 4.1.6.0 for the Nortel Ethernet Routing Switch 8600. Nortel published a bulletin today entitled, “Ethernet Routing Switch (ERS) 8600: System Instability maybe seen after upgraded to 4.1.6.0 software“.

CPU instability issues with Maintenance Release (MR) 4.1.6.0 have been discovered during initial deployment. CPU crash dump events leading to system instability have been reported after the operational SW was upgraded to 4.1.6.0 at different customer site.

There was also an additional note concerning an interaction between Microsoft’s Network Load Balancing (NLB) when running in multicast mode on 4.1.6.0 software code that might result in a CPU crash on the ERS 8600.

Nortel is advising that 4.1.6.0 software has been pulled from their website and replaced with 4.1.6.3 software. They are also advising that 4.1.7.0 software will be available in August 2008.

While I haven’t personally seen this problem I only have 1 switch running 4.1.6.0 software out of the 37 ERS 8600 switches we have in production.

Cheers!
