SSP (WAN Iface) Parameters
VMAC:
Virtual MAC address. The host uses MAC addresses and SAP values as the addressing values
to discriminate between circuits (in much the same way as an IP address & TCP port define an
addressing point for a TCP socket). This is the MAC address that is reported as part of the
DLSw protocol.
Peer VMAC:
The Virtual MAC address of the peer.
IP address:
The IP address of the peer DLSw unit.
Read port:
The read IP port. The TCP socket SNAIP listens on.
Write port:
The write IP port. This TCP socket will be opened by the unit if it needs to start the DLSw pro-
tocol.
TCP socket inactivity timer (s):
This specifies the maximum period of inactivity (in seconds) that may occur before an open
TCP/ IP socket is closed. The default value is 300 seconds (5 minutes) and should not normally
require altering.
DLSw Role:
When this parameter is set to “Active”, and the unit is in SNA mode, then this DLSw switch
will actively connect to the remote DLSw switch.
DLSw Ver:
This parameter controls the DLSw version to be used. Set to 0 (default) for version 1, set to 2
for version 2.
UDP Capable(ver 2):
This controls the UDP transmission of DLSw SSP packets. Reception is always enabled for ver-
sion 2 support. If set to “OFF”, the state transitions occur just like DLSw version 1 but the unit
will indicate it is version 2 capable.
Use 1 socket:
When this parameter is set to “On” then only one socket is used for both read and write data.
This is useful if the unit is behind a NAT box and incoming connections are. This parameter can
also be set to “Compatible”, in which mode both sockets are open to start with and then after
a negotiation one of the sockets is dropped.
Include Mac Exclusivity Capability:
On or Off. Set this parameter to “On” in order to include the MAC exclusivity value in the
capabilities exchange message.
Mac Exclusivity Value:
See above.
Source IP address interface:
By setting this parameter to either “PPP” or “ETH” (Ethernet), the source address used by
SNAIP will match that of the Ethernet or PPP interface specified by the Source IP from interface
# parameter below.
