FNB Configuration View
Access: From the Icon Subviews menu for the FNB
Backplane View, select FNB Config View.
When you open a module’s FNB Configuration
window (see Figure 8), the MAC on the FDDI ring
associated with an SMT entity will usually be in
normal operation on the ring. However, on some
occasions, the ring may be recovering from a
beaconing condition, and RMT (the Ring
Management component of SMT services) is in the
process of initializing or recovering from a ring
failure. If you bring up a module’s FNB
Configuration window during ring initialization or
recovery, the MAC on that ring will be in an
isolated state. The isolated state is depicted as the
MAC positioned above the ring path pair, instead
of connected to one or the other ring path. The
MAC will be color-coded according to its last
known ring path; however, it is not manageable
during this state.
A status message located in the lower left corner
of the FNB Configuration window will inform you
whether you are looking at the Current
Configuration of the module with respect to the
FNB backplane, whether the window has been
changed to a Valid Configuration, whether the
window has been changed to an Invalid
Configuration (in which case you will not be able
to apply the change), or whether the change has
been applied successfully to the device (Set
Success).
