The following are limitations in ExtremeXOS and Switch Engine system architecture that have yet to be resolved.
| Defect Number | Description |
|---|---|
| General | |
| EXOS-30441 | For 25G ports, auto-negotiation is disabled by default in ExtremeXOS. When
connecting an EXOS switch to a VOSS switch via a 25G Direct Attached Cable,
auto-negotiation is mismatched, as the default behavior in VOSS is
"enabled". Workaround: Enable auto-negotiation on the ExtremeXOS port. |
| EXOS-31301 | In an ExtremeSwitching 5320 stack, switches are unable to connect to standby slots using bluetooth. |
| EXOS-31548 | On native 25G ports, Forward Error Correction is turned ON by default. However,
while using QSFP28 ports partitioned for 4x25G operation, Forward Error Correction
is turned OFF by default. Workaround: Enable forward-error-correction on the 4x25G ports. |
| ExtremeSwitching X435 Series Switches | |
| EXOS-32968 | On the ExtremeSwitching X435 series switch, if Fast PoE is enabled and the switch is rebooted (not power-cycled), the switch behaves like perpetual PoE (PoE power delivery on the ports are not interrupted during the reboot). |
| ExtremeSwitching 5520 Series Switches | |
| EXOS-35660 | New 5520-12MW-36W series switches are built with an updated revision of the
PHY, which requires corresponding driver support for proper operation. When an image without appropriate hardware support is downloaded to 5520-12MW-36W switches, the following message is displayed in the log: <Warn:HAL.Card.Warning> Image running on card in slot 1 lacks necessary PHY support. See the User Guide for information on installing a newer software release. See the Hardware/Software Compatibility and Recommendation Matrices to verify the supported releases. |
| ExtremeSwitching 5320 Series Switches | |
| EXOS-31548 | When PRD-5320-10G-8P is applied to the ExtremeSwitching 5320 Series switch, the
DEF-EVAL-10G-4P is not removed, despite the persistent 10G Port Evaluation Days
Remain warning. Workaround: The warning can be disregarded. |
| EXOS-32841 | The following PoE - 54V DC output error log messages are displayed after a full
power cycle on PoE capable switches:
11/03/2022 13:03:20.03 <Erro:HAL.PoE.Error> (summitPoeRecoveryCheck) pse_system_power_query failed. 11/03/2022 13:03:09.99 <Info:HAL.Sys.Info> (halPSDetectionProcessing) Internal Power Supply is disconnected. 11/03/2022 13:03:09.99 <Info:HAL.Sys.Info> (summitPerPsuStatusToHalState) PSU 54V DC output changed. Note: These messages do not occur during
a normal switch reboot, but on a full power cycle only. This is non-impacting to
switch or network functions.
|
| Extended Edge Switching | |
| EXOS-29969 | A hal process failure occurs while running the configure access-list command on ExtremeSwitching 5520 and X590 VPEX stack platforms. |
| Summit Stack | |
| EXOS-35785 | In a stack setup, the Primary and Backup slots have different default FEC
settings. Example: For 25G SFP28 ports in the stack, the default FEC setting on the
Primary node is enabled, while the default on the Backup is
disabled. Workaround: Configure the 25G Backup slot ports with FEC-enabled CL91. |
