Avaya has released software v5.1.4.0 for the Ethernet Routing Switch 8600. There are a few new features in this software release that are designed to further improve the ability of the network to recover from a network/link/switch failure with minimal packet loss.
New Features in This Release
- VLACP HOLD Enhancement
- SLPP – Introduced New EtherType for SLPP PDU
- SLPP – Re-Arm per port SLPP PDU Receive Counter issue
I recently discussed (in the forums) the added benefit of VLACP when recovering from network failures. It seems that Avaya is continuing to build upon that goal with additional enhancements to VLACP to help aid in recovery after a network outage. We also discussed the known issue with SLPP and how it can accidentally trip on occasion given that the counter/threshold is cumulative and never reset. Avaya has refined SLPP to reset the counter every 24 hours thereby eliminating any false positive conditions that might occur over a extended duration (uptime of the switch).
I would encourage everyone to review the release notes for all the resolved and known issues.
Cheers!
Is there a command that resets the SLPP counters manually ?
There is no such command although enabling and disabling SLPP (I believe) would reset the counters. With 5.1.4.0 software the switch itself will clear the counters every 24 hours automatically.
Cheers!
Hi Michael,
Firstly, I would like to thank you for posts knowing the difficulty to find information as sharp and detailed about Nortel.
I am currently working on the upgrade of two 8600 network core. I replaced the existing 8691SF and 8608SXE card by the most recent 8692SF (without SMezz) and 8634XGRS. I had the bad surprise to see that new High Speed Fan tray were required. So we have ordered them and it’s ok since.
Now I wonder which software release should I choose. You mention the v7.0.0.2 and the v5.1.4.0 releases.
1. What would be the best choice for you today ?
I noticed on the v5.1.4.0 release notes that warning :
“R/RS-series modules are supported in the 8010co chassis only with a High Performance Backplane installed.”
Our 8610co were made October 5, 2004 and I don’t really know how to check if they have the High Performance Backplane installed… I seen nothing about that in bootconfig flags
2. Do you know how to check that ?
Thank you for your patience.
Cheers.
Hi Damien,
In order to run 7.x software you’ll need 8692SF with SuperMezz cards so it seems you’ll only be able to run 5.x software at this time unless you decide to purchase the SuperMezz daughter cards for the 8692SF.
Unless you really need full IPv6 support I don’t see any need to rush to 7.x software right now.
Good Luck!
Hi Michael,
So my choice is made.
Perfect, you are my god, sir !
Thank you !

Hi,
Type “show sys info” and check H/W config value. If equal or greater then 2 then You have High Performance chassis. Not sure with 8610co but in classic 8610 only slot 1 and 10 were slow. All others were fine for R/Rs modules.
Cheers,

Hi Artur,
Thank for your reply. It clarifies better that warning :
CPU5 [01/18/11 00:59:37] HW WARNING For maximum performance, Nortel recommends placing R modules in Slots 2-4 or 7-9 only. Insertion of an R-module into Slot 1 or 10 will yield limited performance with existing Chassis Hardware.
I checked the H/W config value and it is equal to 2.
Thank you !
Best regards,
Damien
