One of the consistent issues I (and many network implementors) have with Sonos equipment is dealing with the older/pre-standard STP path costs Sonos equipment presently uses (10 for Fast Ethernet vs the commonly used 19). This is especially problematic with when multiple tiered switches are installed on a network and path cost modification isn’t practical.
Unifi (Ubiquiti) based switching networks can be especially problematic in this regard. Unifi switching can be set to STP or RSTP, but path costing can’t be edited persistently.
With Sonos S2 coming, are there any plans to modernize / update the spanning tree implementation to support the current STP path cost standards, or better yet, support RSTP?
