service.

Note The CAC affects both physical and virtual ports as indicated in the example above

(7b1.3 is a virtual port).

If there are a large number of connections of a particular class of service on a particular port, and these connections

begin to slow down and show signs of congestion, use the set caceqbwallocscheme command to change the CAC

policy to moderate or conservative.

SmartSwitch # set caceqbwallocscheme

PortNumber() : 7a1

SeriveCategory(CBR) : ubr

AllocScheme(LIBERAL) : moderate

SmartSwitch #

Use the set cacserviceclassbw command to change the amount of bandwidth on a per-port basis that the CAC

recognizes as available for each class of service. Available bandwidth for a class of service is specified as a percent of

total port bandwidth. For example, to increase the bandwidth for CBR calls on port 7a1 to 20 percent of total port

bandwidth, enter the following

SmartSwitch # set cacserviceclassbw

PortNumber() : 7a1

MaxBandWidth_In_Percentage-CBR(1) : 20 — Increase to 20%

MaxBandWidth_In_Percentage-RT_VBR(1) :

MaxBandWidth_In_Percentage-NRT_VBR(7) :

MaxBandWidth_In_Percentage-UBR(89) : 70 — Decrease by 20%

MaxBandWidth_In_Percentage-ABR(1) :

SmartSwitch #

Notice in the example above that the total percentage for all service classes on the port must not exceed 100 percent.

Furthermore, if the set cacserviceclassbw command is used to alter a physical port, the change also affects any

virtual ports on that physical port.
