Software Fixes in Releases Y.11.01 - Y.11.16

Release Y.11.07

No Problems Resolved in Release Y.11.07. (Not a Production Build.)

Release Y.11.08

The following problems were resolved in build Y.11.08.

■ MAC Address (PR_0000009750) — If a client moves from one port or switch to another,

the MAC address is not relearned on the new port until the MAC address timer expires on

the original port.

■ STP (PR_0000009592) — Spanning Tree BPDUs are not processed when all VLANs on a

given port are tagged. This may result in multiple root bridges and a Layer 2 loop when

redundant physical paths exist.

■ Transceivers (PR_0000010525) — Intermittent self test failure may occur if transceivers

are hot-swapped in and out of the switch in too short a time frame. Note that even with this

fix, transceivers should always be allowed to initialize fully prior to removal and subsequent

re-insertion.

Best Practice Tip: Upon hot insertion of a transceiver, the mode LED will come on for two

seconds. Once this LED has extinguished, it is once again safe to remove the transceiver.

Release Y.11.09

The following problems were resolved in build Y.11.09. Not a public release.

■ Config (PR_0000002077) — Presence of the valid CLI/configuration parameter spanning-

tree trap errant-bpdu will trigger failure to upload a configuration, with the switch reporting

an error similar to the following (in this example, the problem parameter was on line 16 of

the configuration).

line: 16. trap: Error setting configuration.

Corrupted download file.

■ Loop Protect (PR_0000010897) — The loop detection feature may not function properly

on ports configured with any combination of MAC-Authentication, spanning-tree, and bpdu-

protection.

■ Management (PR_0000005902) — The switch management may become unresponsive,

resulting in loss of Telnet, Web Management, and console access functionality of the switch.

■ SNMP (PR_0000002764) — The SNMP MIB object that allows authenticator functionality

on a port to be enabled or disabled (hpicfDot1xPaePortAuth) can be set to an invalid value.
