VC Traffic Classes for ATM

After you configure the routers with the atm add command, PacketWise automatically creates classes and partitions for the virtual circuits it discovers on the routers it polls. It retrieves the serial interface name from the router and creates a folder class under both /Inbound and /Outbound in the traffic tree. Then, it populates the folder with a child class for each VC it detects.

Note: Do not remove or rename a router folder in the class tree, as it is required to maintain the proper ordering of the VC classes.

PacketWise automatically takes the following steps:

1. It creates a folder class for each router's interface using the following name format: <sysname>-<ifname>
   
   <sysname> is the router's system name and <ifname> is the internal name of the router's serial interface.
   
   For example: /Inbound/router1-AT0_0
   
   
2. Under each router folder class, it creates a child class for each VC that exists on the given router, using the following convention: PVC_vpi_vci where vpi represents the VPI value and vci represents the VCI value for the VC.
   
   For example: /Inbound/router1-AT0_0/PVC_1_42
   
   Note: The class names start with PVC regardless of the type of virtual circuit.
   
   Matching rules are configured automatically, based on the IP routing tables in the router.
   
   
3. If traffic discovery is turned on, PacketWise creates child classes under each VC class for the applications and protocols it detects on that VC.

The Inbound portion of an ATM traffic tree might look something like this:

Inbound
   router1-AT0_0
     PVC_1_42
       HTTP
       FileMaker
       NetBIOS-IP
       ...(other classes)
     PVC_1_43
       HTTP
       POP3
       FTP
       Oracle-netv2
       NetBIOS-IP
       ...(other classes)
     PVC_1_44
       HTTP
       POP3
       MPEG-Audio
       Telnet
       NetBIOS-IP
       ...(other classes)
    router2-AT1_0
      PVC_1_604
        HTTP
        POP3
        NetBIOS-IP
        ...(other classes)
      PVC_1_605
        HTTP
        POP3
        NetBIOS-IP
        ...(other classes)
