Configuration prerequisites

Patches are released per switch model or card type. Before patching the system, you need to save the
appropriate patch files to the switch's storage media using FTP or TFTP. When saving the patch files, note
that the following guidelines:
• The patch files match the switch model and software version. If they are not matched, the hotfix
operation fails.
Name a patch file properly. Otherwise, the system cannot locate the patch file and the hotfixing
•
operation fails. The name is in the format of "patch_PATCH-FLAG suffix.bin". The PATCH-FLAG is
pre-defined and support for the PATCH-FLAG depends on card type. The first three characters of the
version item (using the display patch information command) represent the PATCH-FLAG suffix. The
system searches the root directory of the storage medium (Flash by default) for patch files based on
the PATCH-FLAG. If there is a match, the system loads patches to or install them on the memory
patch area.
The following table describes the default patch name for each card type.
