link is established and optional facilities are negotiated as needed by the LCP, the
originating PPP sends Network Control Protocols (NCP) packets to select and
co
nfigure one or more network layer protocols. When each of the chosen network
layer protocols has been configured, packets from each network layer protocol can
be sent over the link. The link remains configured for communications until explicit
LCP or NCP packets close the link, or until some external event occurs. This is the
actual switch port link type. It may differ from the administrative state.
4.9.5 MSTP Properties
MSTP provides differing load balancing scenarios. For example, while port A is blocked in one STP
instance, the same port is placed in the Forwarding State in another STP instance. The MSTP Properties
screen (see figure 4-50) contains information for defining global MSTP settings, region names, MSTP
revisions, and maximum hops.
The page contains the following fields:
• Region Name
• Revision
