Q&A: How to configure uplink port protect-group on MA5600T

A:
We can protect uplink ports on MA5600T by using "protection group" configuration:

ma5600t(config)#protect-group 1 protect-target eth-nni-port workmode timedelay
ma5600t(protect-group-1)#protect-group member port 0/19/0 role work
ma5600t(protect-group-1)#protect-group member port 0/19/1 role protect

ma5600t(config-protect)#display protect-group
{ |pgid<0,63> }:
command:
display protect-group
-----------------------------------------------------------------------
group id : 1
admin state : enable
-----------------------------------------------------------------------
member role operation state peermember
-----------------------------------------------------------------------
0/19/0 work auto switch src standby 0/19/1
0/19/1 protect auto switch dst active 0/19/0
-----------------------------------------------------------------------
total : 1



software version is v800r007c00spc300.

In this case switchover between active and passive links is scheduled by timedelay mode.
   Timedelay mode means, that only one transmission port of the protection group is open. When the open transmission port is in the down state, the port is closed and the other transmission port is open. if the second port is in the up state, the switchover is performed, otherwise the checking is still going on.   Timedelay value is 100 ms and can not be changed.
