The following are limitations in ExtremeXOS and Switch Engine system architecture that have yet to be resolved.
|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
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.
Enable forward-error-correction on the 4x25G ports.
|ExtremeSwitching X435 Series Switches|
|EXOS-32881||On the ExtremeSwitching X435-8p-4s switch, downgrading from version 31.7 to 30.7 can render the PoE permanently inoperable, resulting in an RMA being needed to recover PoE functionality.|
|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
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.|
