AIM2-A2-GZ40-20
Virtual Path Identifier (VPI). A VPI is designated by an 8-bit field in ATM cell
headers and a VCI is designated by a 16-bit field in ATM cell headers. The
AIM24000 supports one PVC per port.
On – An AIM24000 port with VPI/VCI Detect on will automatically monitor the
line to determine the VPI and VCI settings of the remote ADSL modem to
which it is connected, and set itself accordingly. If no ATM cells are detected
(at any VPI/VCI setting), the port will default to VPI 0 and VCI 35. Thereafter,
once it does detect ATM cells from the remote ADSL modem, it will
reconfigure VPI and VCI to the same settings at which the ATM cells from the
remote ADSL modem were detected.
Off – An AIM24000 port with VPI/VCI Detect off will default to VPI 0 and VCI
35 unless the port was previously set at VPI/VCI Detect on and had already
detected the VPI and VCI settings of the remote ADSL modem. In this case,
turning the VPI/VCI Detect function off will lock in the previously detected
settings unless the VPI and VCI values are altered manually.
Manual – If you wish to set VPI and VCI values manually, VPI/VCI Detect
should be set to off defore the VPI and VCI values are entered. When
manually configuring VPI and VCI, each port on the AIM24000 must be
assigned the same VPI and VCI values as the remote ADSL modem to which
that port is connected in order for the units to communicate.
Protocol Setting
Default: Allow All
Traffic protocol is indicated by a 2-byte (hexadecimal) Ethertype code in packet
headers.
Allow All – An AIM24000 port configured with Protocol All will allow packets
with all Ethertype protocols to traverse the port.
Allow Selected or Disallow Selected – You can specify up to four Ethertype
protocols. If Allow Selected is active, only packets with the specified
Ethertypes will be allowed to traverse the port. If Disallow Selected is active,
packets with the specified Ethertypes will not be allowed to traverse the port.
The port is automatically set to accept 0800 (IP) and 0806 (IP ARP) packets.
NOTE: Not all BLC management modules provide the Protocol Select option
in NMS, and the Select option is not available via CLI or SNMP. In these
instances you will be required to choose between All or IP, where IP indicates
that only Transmission Control Protocol (TCP), Internet Protocol (IP) and
Address Resolution Protocol (ARP) traffic will be allowed to traverse the port.
Layer 2 Port Filter Settings
Default: Inactive
Select the checkbox next to Layer 2 Port Filter Settings if you want to control traffic
according to MAC addresses.
MAC 1, MAC 2, MAC 3
Specify up to three MAC addresses permitted to traverse the port.
