Configuring a WAN InterfaceNote:Note: Dynamic CAC works in conjunction with the Communication Manager CallAdmission Control: Bandwidth Limitation (CAC-BL) feature. For moreinformation, refer to Administrator’s Guide for Avaya Communication Manager,555-233-506.You can enable dynamic CAC on the following interface types:● Fast Ethernet●●●Serial (PPP or frame relay)GRE TunnelVLANNote:Note: Since VLAN interfaces are always up, configuring Dynamic CAC on a VLANinterface provides a means to have a default Dynamic CAC bandwidth.Use the dynamic-cac bbl command in interface context to enable dynamic CAC on theinterface and set the maximum bandwidth for the interface. The dynamic-cac bbl commandincludes the following parameters:●bbl — The bearer bandwidth limit (kbps). The MGC enforces this as the maximumbandwidth for the interface. If you set the bbl to 0, the interface can only be used forsignalling.● activation priority (optional) — If dynamic CAC is activated on more than oneactive interface, the G350 reports the bearer bandwidth limit of the interface with thehighest activation priority. You can set the activation priority to any number between 1 and255. The default activation priority is 50.The following example sets dynamic CAC on Fast Ethernet interface 10/2, with a bearerbandwidth limit of 128 and an activation priority of 100:G350-001# interface FastEthernet 10/2G350-001(super-if:FastEthernet 10/2)# dynamic-cac 128 100Use the show dynamic-cac command to display bandwidth information about the interface.The show dynamic-cac command displays the following information:●●●Current RBBL — The current actual bandwidth available on the interface.Last event — The amount of time since the most recent update by the CAC process.Last event BBL — The interface’s bandwidth at the time of the most recent update by theCAC process.Note:Note:Dynamic CAC also requires configuration of the MGC.
