pvcsif -- configure ATM PVC sub interfaces SYNOPSIS
pvcsif interface [-s] pvcsif -a DESCRIPTION
pvcsif creates a sub interface for an ATM PVC. A sub interface pvc(4) is dynamically created. The created interface is bound to interface but at this point no VC is assigned. To assign a VC, pvctxctl(8) should be used later. A PVC sub interface is intended to use an ATM PVC as an alternative serial connection, and to be allocated per PVC basis. A PVC sub inter- face looks as a point-to-point interface and is multicast capable, as opposed to the NBMA (NonBroadcast Multiple Access) model that requires a MARS server. A point-to-point interface is useful to run MBone or protocols requiring multicast, such as RSVP and IPv6, over a PVC WAN connection. Note that a sub interface is not a full-fledged interface but just an indirect reference to the real interface. The options are as follows: -s For use with a shell, it prints the created interface name. -a Lists the existing sub interfaces. SEE ALSO

Currently, there is no way to remove a sub interface. BSD

br2684ctl(8) System Manager's Manual br2684ctl(8) NAME
br2684ctl - RFC1483/2684 Bridge Daemon SYNOPSIS
br2684ctl [ -b ] [[ -c n ] [ -e 0|1 ] [ -p 0|1 ] [ -s sndbuf ] [ -a [itf].vpi.vci ]] ... PARAMETERS
-a [itf].vpi.vci ATM PVC number, VPI and VCI. (Required) -b Puts the process in the background. -c n br2684 interface number such as 0, 1, ... (Required) -e 0|1 Encapsulation method: 0=LLC, 1=VC mux (the default is 0 or LLC) -p 0|1 Payload method: 0=Routed, 1=Bridged (the default is 1 or Bridged) -s sndbuf Send buffer size. Default is 8192. DESCRIPTION
br2684ctl handles RFC1483/2684 bridged PDUs. This is most often used in ADSL scenarios where usually the subscribers' ethernet traffic is encapsulated in ATM AAL5 (by bridging ADSL modems) according to RFC2684. The subscriber-side ADSL modem can be external with an ethernet connector or an internal ADSL card in a PC. RFC1483 has been obsoleted by RFC2684. For example it is possible to set up your Linux box to handle several ATM PVC's with bridged-1483 (sometimes referred as SNAP) encapsula- tion. The Linux network stack might provide DHCP, IP masquerading, IP firewall services or bridge the Ethernet frames just like it had several ethernet interfaces. In fact it can have several (logical) ethernet interfaces, where ATM is just used as a carrier. USAGE
br2684ctl creates a new network interface named nas[n] which is bound to an specific ATM PVC. It requires two mandatory arguments: -c, the interface number, and -a, the ATM PVC. It should be noted that the order of the command arguments matter; -c should be followed by -a. You can create as many interfaces as necessary in one go, just make a long command line ;) For example, following command will create a nas0 interface which uses the ATM PVC with VPI=0 and VCI=401. You need to configure the PVC connection 0.401 on the ATM switch manually. % br2684ctl -c 0 -a 0.401 The command will only create a new interface nas0. Next step is to assign an IP address and netmask to the interface nas0 using the ifcon- fig command. Using ifconfig, you can also assign a Ethernet MAC address to the interface nas0, if necessary. % ifconfig nas0 192.168.2.1 netmask 255.255.255.0 Messages are logged to the LOCAL2 syslog facility.
