STEP THREE
Up to this point, the configuration can be used either for link back up or for load back up. This example shows link back up, but parameters applicable to load back up will be mentioned when they appear. Complete information on the multilink circuit concept is provided in chapter 4 of the CyROS Reference Guide.

Parameter | Example | Your Application |
Criterion for Traffic | This parameter has no effect for link backup. For load |
|
Distribution | backup, Optimal distribution is performed randomly, and the |
|
| packet is forwarded to the interface with the lesser load. |
|
| Address Based distribution is used when the receiver cannot |
|
| reorder packets, and all packets to a certain IP address must |
|
| be sent through the same interface. This distribution method is |
|
| not recommended unless absolutely necessary. |
|
Bandwidth Upper | Zero for link backup. For load backup, this defines when load |
|
Limit | backup should activate the backup link. It is measured as a |
|
| percentage of the bandwidth defined in step four. |
|
Time to Activate | This parameter does not appear for link backup. Time until |
|
Backup if Above Limit | backup is activated after main link bandwidth exceeds limit |
|
| defined in last parameter. |
|
Bandwidth Lower | This parameter has no effect for link backup. For load |
|
Limit | backup, this defines when load backup should deactivate the |
|
| backup link. It is measured as a percentage of the bandwidth |
|
| defined in step four. |
|
Time to Deactivate | This parameter does not appear for link backup. Time until |
|
Backup if Below Limit | backup is deactivated after main link bandwidth exceeds limit |
|
| defined in last parameter. |
