Displaying And Maintaining The Backup Center; Configuring Load Sharing - 3Com MSR 50 Series Configuration Manual

Configuring Load
Sharing
Displaying and
Maintaining the
Backup Center
Follow these steps to associate an interface with a Track object:
To do...
Enter system view
Enter interface view
Associate an interface with a
Track object
The backup center detects the data traffic on the main interface to decide
whether to bring up or shut down the backup interface.
Follow these steps to configure load sharing:
To do...
Enter system view
Enter main interface view
Configure the available
bandwidth used for setting
the thresholds
Configure load sharing
thresholds
Configure the interval for
detecting traffic size on the
main interface
n
When multiple backup interfaces are assigned the same priority, they are brought
up or shut down depending on the order they are configured
The backup interface configured first is used first to participate in load sharing
■
with the main interface.
The backup interface configured later is shut down first and exits load sharing
■
with the main interface.
c
CAUTION:
If the available bandwidth used for setting the thresholds is 0kbit/s (the default
■
value), the backup center automatically obtains the available bandwidth
provided by the system to set the thresholds. If the backup center fails to
obtain the physical bandwidth, it would prompt you to reconfigure.
If the available bandwidth configured for setting the thresholds exceeds the
■
physical bandwidth on the interface, the load balancing does not take effect.
Follow these steps to display and maintain the backup center:
Use the command...
system-view
interface interface-type
interface-number
standby track
track-entry-number
Use the command...

interface interface-type
interface-number
standby bandwidth size
