Sync port should not send or receive data when WAN link is down
Causes the Sync port to be deaf and dumb (and have DCD low) while the connection with the
WAN is down. This setting is supported to prevent terminals from assuming if L2 is up, the rest
of the WAN link should be working, at which point the router could go into a management error
state.
3. Configure SNA parameters
Router to be Master on an unbalanced link
Enable this parameter if this router is to be the master in an unbalanced link, or set to Off if
the router is to be a secondary station.
Polling Response Time
The poll time, in milliseconds, if the router is the master in an unbalanced link.
Polling Stations Addresses
This parameter is only applicable in SNA mode. Lists the station addresses on the data link as a
comma-separated list of hex values, such as c1,d1 for station addresses 0xc1 and 0xd1.
SAPs
A list of SAP values which correspond to the station addresses.
DSAPs(blank=default)
The Destination SAP value, if left blank the router uses the SAP value specified above.
Send Null XID (XID with no Data)
When this parameter is set to On, a null XID SSP message will be sent when the router has just
received or sent a REACH ACK SSP message.
Send XID with Data
A hex string to define binary data and defines an XID SSP message that would be sent in
response to a XIDFRAME SSP message being received.
Tx Turn Around Time
The time, in milliseconds, between receiving a frame from an outstation and transmission back
to the same station. If this parameter is set to 0, this is disabled and the router can respond
immediately. The minimum non-zero value is 10ms.
Mode
Defines the mode in balanced links, such as HDLC. In unbalanced links such as SNA/SDLC, the
mode is defined by being master or the station.
