Switch Command Interface (SWCI)

SWCI Commands

SWCI executes each command as it is entered and displays results in the TACL window

from which SWCI was started (or to an alternate terminal or file if specified in the

TACL RUN command). SWCI continues to execute commands until it encounters either

an EXIT command or (if input is from a file) an end-of-file condition . Any invalid

command or other error condition detected by SWCI during command execution results

in an error message; but does not terminate SWCI. SWCI commands have a timeout

value of one second, except the SELFTEST command, which has a timeout value of

three seconds. For examples on using SWCI commands for planned and unplanned

outages, see Section 5, Switchovers

The SWCI commands are summarized in Table 6-1

, and are categorized into three types:

•

Action

•

Control

•

Status
