Changing the hello and preforwarding times
You can also change the RHP hello time and preforwarding time. To do so, enter commands such
as the following.
Brocade(config-vlan-2-mrp-1)# hello-time 200
Brocade(config-vlan-2-mrp-1)# preforwarding-time 400
These commands change the hello time to 200 ms and change the preforwarding time to 400 ms.
Syntax: [no] hello-time ms
Syntax: [no] preforwarding-time ms
The ms specifies the number of milliseconds.
The hello time can be from 100 – 1000 (one second). The default hello time is 100 ms.
The preforwarding time can be from 200 – 5000 ms, and must be at least twice the value of the
hello time and must be a multiple of the hello time. The default preforwarding time is 300 ms.
A change to the hello time or preforwarding time takes effect as soon as you enter the command.
NOTE
You can use MRP ring diagnostics to determine whether you need to change the hello time and
preforwarding time. Refer to
Changing the scale timer
You are able to decrease MRP convergence time by changing the MRP scale timer tick from 100 ms
to 50 ms. To do so, enter the following command:
Brocade(config)# scale-timer mrp
Syntax: [no] scale-timer mrp
Note: This command accepts no values and is put in place as it is shown above.
Note: Changing the scale timer affects the operation of MRP. Refer to

further information.
