There are multiple 'best practice' Avaya design documents available in regards to switch clustering, however, the latest of these that I have found is from 2015. One issue we're hitting at the minute is the determining the current recommended best practice for deploying SLPP in an SMLT environment. The latest product documentation sets contain the following in regards to SLPP port thresholds -
Primary switch - 5
Secondary switch - 50
Avaya recommends that you configure the rxthreshold above 50 slpp packets only on lightly
loaded switches. If you configure the rxthreshold to a value greater than 50 on a heavily loaded switch and a loop occurs, the system can experience high CPU utilization.
which contradicts previous recommendations of multiples of the number of VLANs tagged on the port with a maximum of 500 (incredibly frustrating to keep tabs on in a large environment). It does also raise the question of how a 'lightly loaded' switch is measured.
My reason for raising is that during a network outage last year Extreme/Avaya advised on setting CP limit values to the recommended values in the product documentation which completely went against those that were the 'best practice' values on which the deployment was based.
Does anyone have any comments as to whether the product documents should now over rule the older best practice guides?
