New Features
SFTOS 2.5.3 improves SFTOS internals only, with no new features.
SFTOS 2.5.2 adds:
• A substantial support interface that is not accessible through the standard CLI modes and is not
publicly documented
• Support for new S-Series platforms, including the S50N, S50N-DC, and S25P-DC
Other Changes to the Document
Changes in this edition include:
• The major change in this edition is that the example configuration sequence for VLAN Stacking is
corrected. See Configuring a VLAN Tunnel (DVLAN or VLAN-Stack) on page 229.
Changes to this book in the previous edition included:
• The SFTOS Web User Interface (Web UI) chapter is removed, because changes to SFTOS 2.5.2.1 were
not promulgated to the Web UI, which made some parts of the Web UI unreliable or non-functional.
• The ACL chapter now states that both MAC and IP ACLs can be applied to the same interface.
• Both the VLAN and LAG chapters state more explicitly that the Default VLAN, VLAN 1, cannot be
changed, and will not allow a LAG or tagged port as a member of it.
