* Description of footnoted commands (also applies to identical stages in configuring
Site B):
(1) At this stage you apply Priority 7 to Voice Control traffic.
(2) At this stage you apply Priority 6 to RTP traffic.
(3) At this stage you apply maximum trust between 802.1p priority and DSCP.
(4) At this stage you are matching the RTP port range used for RTP compression, to
that of the CLAN.
(5) At this stage the default queue size is 60, and since cRTP is enabled you can
increase the VoIP queue size.
