SNA Port Parameters
Table 11-1 lists all SNA Port parameters, and explanations of most parameters follow
the table. Note that not all parameters will be displayed in any one record—some are
FRX8000 only, some N7000 only. Also, some parameter values determine which
other parameters will be displayed.
1
Applicable only to TPAD ports. If configuring an HPAD port, accept the default.
2
In increments of 20.
3
Must be configured the same as the physical device on the remote end of the connection.
4
Applicable only to HPAD ports. If configuring an TPAD port, accept the default.
Physical Interface
is the hardware interface. On an AST LP, this is always RS-232. On an RLP, the
interface is determined by the associated Line Interface Card (LIC) and the cable
attached to the port's I/O box connector. The LP record identifies the LIC, and only
the valid interfaces will be displayed as choices in the Port record.
