Required Action 
Steps 
Configure Port Groups 
This command determines what combination of port failures will 
invoke RLS. 
Sequence: 
 get rls port group press Enter 
The system responds: 
 Rls port group configuration 
 Ports :P1 P2 P3 P4 
 Combination :any 
The above response indicates that any one port P1 through P4 needs 
to fail and RLS will be invoked. 
 set rls port group [p1[ [p2] [p3] [p4] [any|all] press Enter 
Example 1: 
 set rls port group p1 p2 p3 p4 all press Enter 
The system responds: 
 Rls port group configuration 
 Ports :P1 P2 P3 P4 
 Combination :all 
The above response indicates that RLS will only be invoked when all 
of ports P1 through P4 have failed. 
Example 2: 
 set rls port group p3 any press Enter (“any” or “all” works for this 
example) 
The system responds: 
 Rls port group configuration 
 Ports : P3 
 Combination :any 
If P3 fails RLS will be invoked. 
Configure rls make rsl 
This is an optional command. This command sets the minimum RSL 
value required to re-establish, or “make”, the link. 
Sequence:  
set rls make rsl [RSL (dB)] [Duration (sec)] press Enter 
The system responds: 
RLS Make RSL Parameters: [RSL (dB)] [Duration (sec)] 
Example: set rls make rsl -60.0 100 
When the RSL level is maintain at -60.0 or a higher value (less 
negative) for the duration of the sample period (100 seconds), the link 
will be re-established. 
Setting the RSL sample period to zero (0), the default value, disables 
this feature.
