Re: [802SEC] Responses to Comments on 802.1 PARs

In the 802.1Qbg PAR there appears to be an "s." in 8.1. I expect that
this is a typo.
Thanks for considering my comments, the PARs and 5Cs look good.

This is supported by experience in existing deployments of this technology. In addition, the resultant reduction in management complexity brings significant cost advantages. The port extender creates many lower cost ports for every controlling bridge port further benefiting the overall system cost. Existing experience also indicates no significant increase in the cost of the bridges that attach to the Port Extenders."

Well, it isn't intuitive to me. Please explain why port extenders lead to a cheaper system. In particular, if it reduces the cost of one device, does it increase cost in another? Is the cost reduction significant?
