Administrator

Modifies the CAC parameter scheme used for bandwidth calculation. Three different levels can be set for each port.

LIBERAL: More calls are admitted. These can total up to 4,000 VCs per switch with aggressive allocation of bandwidth, reserving less bandwidth for each connection.

MODERATE: A moderate allocation is a balance between the number of calls versus the bandwidth for each connection. Moderate allocation admits fewer calls and more bandwidth per call than a liberal setting.

CONSERVATIVE: A conservative allocation allocates more bandwidth for each connection. Conservative allocation admits fewer calls and more bandwidth per call than a moderate setting.
