Avaya Switch Clustering using Split Multi-Link Trunking (SMLT) Technical Confiugration Guide

Avaya has released an updated version of their technical configuration guide outlining how to deploy switch clustering using Split Multi-Link Trunking (SMLT) on the Virtual Services Platform 9000, Ethernet Routing Switch 8600, 8300 and 5000.

This is really great document that helps to outline the best practices when deploying an IST/SMLT configuration within your network.

Here’s the summary of the document updates for March 2011;

March 2011 – Added recommendation to use MLT advance mode on edge Ayava stackable switches when used with ERS 8000 square/full mesh topologies for IP based traffic. Changed VSP CP Limit configuration from port level to MLT level. VRRP hold-down timers can be set in the ERS 5000 6.2 release.

It’s well worth the read in my opinion.

Cheers!

 

Upgrading DPC FPGA firmware – Part 2

April 30, 2011

I recently upgraded a number of Ethernet Routing Switch 8600s to v5.1.5.1 software and had to upgrade the DPC FPGA firmware on the R modules (8630GBR, 8683XLR) within the chassis. I previously covered how to upgrade the DPC FPGA firmware but in the last few upgrades I noticed a recurring error message while the upgrade was in progress. I noticed this problem when upgrading both the 8630GBR and 8683XLR modules when the switch at had dual 8692SF w/SuperMezz daughter cards. I don’t previously recall this error message but I believe it started with 5.1.3.1 software or later. The error message can be safely ignored… although they are annoying as they constantly fill the console screen output.

There’s reference to this issue in the 7.0 and 7.1 release notes.

There are no specific FPGA upgrades required with release 7.0.

Ethernet Routing Switch 8600 Software Release v5.1.5.1

Avaya has released software v5.1.5.1 for the Ethernet Routing Switch 8600. It should be noted that Avaya has pulled software release 5.1.5.0 from their website. The release notes indicate that the reason for this was “a datapath issue has been identified that may impact the ability to learn MAC addresses and forward packets for which the source MAC address is unknown. This will only happen if the traffic enters the same LANE as the IST is located on and if the IST occupies the first port in the LANE. Also, this is only seen on card types 8630GBR, 8648GBRS, 8634XGRS and 8612XLRS. (wi00866354)”.

Cheers!
