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 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. |
