The following are limitations in ExtremeXOS system architecture that have yet to be resolved.
| Defect Number | Description |
|---|---|
| General | |
| EXOS-27922 | Beginning with ExtremeXOS 31.2, PTPv2 is not supported on X460-G2 and X670-G2 switches. |
| EXOS-28479 | For ExtremeSwitching 5520 and 5420 series switches, inner tag dot1P is not examined with LAG. |
| EXOS-29242 | Multihop EBGP sessions established over GRE tunnels configured in user VR do not appear when there are more than 5 sessions. |
| EXOS-35325 | Legacy Netlogin Mac authentication fails on ports that were initially part of
VNIs. Workaround: Use Policy mode with VXLAN. |
| ExtremeSwitching X690 Series Switches | |
| EXOS-35327 | Policy_VxLAN: On ExtremeSwitching X690 series switches, traffic on a load sharing port is not tunneled to the neighboring switch after disabling and enabling Policy. |
| ExtremeSwitching 5420 Series Switches | |
| EXOS-28685 | Path MTU discovery and IP fragmentation does not work when a packet is L3 routed to a VPEX extended port on the ExtremeSwitching 5420 series switch controlling bridge platform. Other controlling bridges are not affected. |
| EXOS-28964 | Due to limited RAM, the following warn logs are observed when attempting to
install a summit-arm image in a 5420 or 5420
stack:<Warn:EPM.Upgrade.State> Upgrade status Installation time may be greater than expected due to a lack of memory resources <Warn:HAL.Sys.Warning> Switch low on Memory. OS KBytes total 1002660 free 4992. This can occur normally during image upgrade. |
| Extended Edge Switching | |
| EXOS-29130 | GRE Tunnel IPv4 traffic software gets forwarded if extended port is used in the tunnel transport VLAN. |
| SummitStacking | |
| EXOS-28766 | A file system corruption occurs when a USB clone tar saved with ExtremeXOS
31.3 is used for cloning by an ExtremeXOS or earlier release. Workaround: Upgrade the device to ExtremeXOS 31.3 before performing the clone. |
