Color Status and
Propagation
An extensive context status notification scheme is supported in the ATM
and VLAN Management software.
The same network event may cause different status on different logical
maps/icons. For example, an LEC that cannot join its LES is considered a
critical event in the LAN Emulation Map and not necessarily a fault in the
ATM or Device map. The severity depends on the context or the logical
domain. Colors propagate upwards to the parent icon, so that the next
highest level window’s color is influenced.
There are high-end platform-configured icon status colors defined for
Transcend icons. Each status has a default color that can be changed by
the user.
