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.
