Overview of Threshold Groups

Threshold groups combine VCs/VPs to determine per-connection thresholds, based on the use of
memory by the group.
Note Threshold groups are supported on the Catalyst 8540 MSR, and on the Catalyst 8510 MSR and
LightStream 1010 ATM switch routers equipped with the FC-PFQ feature card.
The initial default configuration of per-VC queueing on the switch has all connections of a service
category assigned to one threshold group. However, the assignment of service categories to threshold
groups is configurable. A service category cannot be mapped to more than one threshold group. If you
configure a service category to a threshold group more than once, the last configuration stays in effect.
The default assigns each service category to a different threshold group. However, you can assign more
than one service category to a threshold group.
The configuration of threshold groups is static, not dynamic.
Note
For a description of how the threshold group feature works, refer to the Guide to ATM Technology.
