Bug Fixes in this Firmware Version

3864399

Description: Sending pFRN packets to ports that were connected to themselves (loop), caused the switch hanged due to semaphore lock mismatch.

Keywords: pFRN

Discovered in Version: 31.2012.2108

Fixed in Version: 31.2012.4036

3860421

Description: Incorrect buffer configuration for trap and mirror packets may cause the switch data path to become stuck, potentially resulting in buffer overrun and internal credit leakage.

Keywords: Data Path, Buffer

Discovered in Version: 31.2012.2108

Fixed in Version: 31.2012.4036

3700332

Description: Updated the ratio between the amount of data sent (TX) to FCCL packets to be determined by the credit size; credit packet will be sent after roughly 4096B of sent data.

Keywords: FCCL, Credit Packet

Discovered in Version: 31.2012.2014

Fixed in Version: 31.2012.4006

3657798

Description: During the transition from 2x split to 4x split port configuration, the procedure for clearing routing logic for management ports was incorrect.

Keywords: Management Ports, Split

Discovered in Version: 31.2012.3008

Fixed in Version: 31.2012.4006

3753126

Description: Interference on the AC line may cause a wrong reset sequence, which leads to a system error and causes all ports to be in link-down mode. Only a power cycle restores the switch to a normal operation mode.

3773771

Description: HBF (Hash Based Forwarding) configurations were applied on the incorrect port.

Keywords: Hash Based Forwarding

Fixed in Version: 31.2012.4006

3707400

Description: In cases where buffer is overutilized, failure to allocate a buffer for the SHARP TX retry buffer may lead to buffer oversubscription.

Keywords: SHARP, Buffer

Discovered in Version: 31.2012.2108

Fixed in Version: 31.2012.4006

3724050

Description: The PRBS register could not be properly disabled. To solve this, the Ethernet FSM closes upon receiving an Enable event without a lock only when the FSM is already in the Close state.

Keywords: Ethernet FSM, PRBS

Fixed in Version: 31.2012.4006

3824931

3843040

Description: Illegal packets of a permissive LID (0xFFFF) and VL other than 15 were incorrectly configured to destined for port 0 and be proceeded by the switch firmware, which lead to overloading of the switch firmware.

Keywords: Checks
