Software Release 2.6.4 13
Software Release 2.6.4
C613-10404-00 REV A
Regressing to previous software releases
If software release 2.6.4 is installed on the switch and then a previous software
release that supports only DOS 8.3 format is installed (see Table 4), long file
names that were in DOS 28.3 format are truncated to DOS 8.3 format. When
software release 2.6.4 or later is reinstalled, these truncated file names are
restored to their DOS 28.3 format and no information is lost. Support for long
file names in only DOS 8.3 format is a feature of software releases prior to
software release 2.5.1.
If software release 2.6.4 is installed on the switch and then a previous software
release that supports DOS 16.3 format is installed (see Table 4), long file names
in DOS 28.3 format are permanently truncated to DOS 8.3 format. For example,
the file
AB12345678.SCP is permanently renamed AB123~01.SCP. Any long file
names that were in DOS 28.3 format remain truncated in DOS 8.3 format when
software release 2.6.4 is reinstalled. Support for long file names in DOS 16.3
format is a feature of software release 2.5.1 up to software release 2.6.4.

Testing Asynchronous and Switch Ports
For the enable test interface and disable test interface commands, the
interface parameter has been expanded. As well as the existing testable
interfaces, you can now test the following interfaces on all products with
switch ports:
■ asyn port n, using interface=asynn (for example, interface=asyn0)
■ switch port n, using interface=portn (for example, interface=port8)
This functionality is already available on AR400 series routers.
For more information, see the Test Facility chapter of the Software Reference.
Interrupting Text Flow with the CLI
A new function has been added for users of the Command Line Interface (CLI)
to let them interrupt (or “break”) text paging or continuously streaming text.
The key combination is Ctrl-Q.
This capability will be useful with stand alone commands such as show
commands that display many output screens. The text is buffered and
undisplayed text is deleted. The command prompt is then restored.
The paging prompt will continue giving users the option to display the next
line of text output or next page, print text continuously with no further
prompts, or abort text output.
This functionality will not work on commands that produce output of
indeterminate length, such as enable and disable commands where output
starts with enable and stops with disable.
