Using the Hub
LEM Rejects
This parameter lists the number of times a link is removed because the error rate
has exceeded the threshold test, as determined by the link error monitor (LEM).
LEM Count
This parameter provides the aggregate link error count, which is set to zero only
on station initialization.
The aggregate link error count is determined by the
link error monitor (LEM).
Show Ring State
To determine the Ring Management (RMT) state of the primary MAC, enter the
show ring
command.
Figure 5-8 shows a sample MAC RMT state, in which the
ring is operational.
>sh ring
Current RMT state: Ring_Op

Display of a MAC’s Ring Management State
The Ring Management (RMT) values that can appear in the
show ring
display
are defined in Table 5-7.
