Redundant Controller Support
In the event that a Layer 3 redundant switch controller or element
fails, the switch resets itself and records an entry of the event in the
event log.
SNMP
To disable SNMP, you must set the access for all community strings
to None. You cannot disable SNMP by deleting all community
strings because the public community string is restored when you
reboot the switch.
Software License Keying
Field upgradeable software features, such as routing, are supported
only by v5.1.0 and later.
Spanning Tree Protocol (STP)
In release 4.1 and later, the STP Port Priority range has been
changed. The values are now 1 to 15. If you changed the
default range in an earlier release, you should verify that the
priority is within the allowed range.
When the STP mode is set to IEEE 802.1D, Bridge Protocol
Data Units (BPDUs) are sent out ports that are configured as
Clear (non-trunked) even if the port is configured as a trunk
(3Com, IEEE 802.1Q, or Dual-Layer) port. To alleviate this
problem, disable STP for that port.
3Com Tagging
3Com tagging is not supported for this release.
TFTP File Naming Standard for Embedded NVRAM File System
* Note: All NVRAM files must use an 8.3 format for file names.
When downloading code to the NVRAM file system, use standard
8.3 file naming conventions.
