SSP (WAN) parameters
Virtual MAC Address
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 reported as part of the DLSw protocol.
Virtual MAC Address of Peer
The Virtual MAC address of the peer.
IP address of the Peer DLSw unit
The IP address of the peer DLSw unit.
Listen on Port
The read IP port. The TCP socket SNAIP listens on.
Use Port x if this unit starts the DLSw protocol
The write IP port. This TCP socket will be opened by the router if it needs to start the DLSw
protocol.
Use interface for source IP address
Setting this parameter to a PPP or ETH instance causes the source address for this SNAIP
instance to match that of the Ethernet or PPP interface specified.
Close TCP connection if it is idle for x secs
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). Normally it is not necessary to change this
parameter.
DLSw Ver
The DLSw version to use. Set to 0 (default) for version 1, set to 2 for version 2.
DLSw Role
When this parameter is set to Active, and the router is in SNA mode, this DLSw switch actively
connects to the remote DLSw switch.
DLSw Window
The DLSw window size. The value range is from 10 to 100. The default is 20.
UDP Capable
Controls the UDP transmission of DLSw SSP packets. Reception is always enabled for version 2
support. If set to OFF, the state transitions occur like DLSw version 1, but the router indicates it is
version 2-capable.
