The following are limitations in ExtremeXOS system architecture that have yet to be resolved.
| Defect Number | Description |
|---|---|
| General | |
| EXOS-30041 | A 'V' flag is displayed in the output after running the show dns cache command with dnssec disabled. |
| ExtremeSwitching 5420 Series Switches | |
| EXOS-29777 | On a stacked 5420, ingress mirroring MACsec-encrypted traffic to a port on a
different slot will result in an extra 4 byte zero-value header inserted in the
position of the VLAN tag. Workaround: Mirroring such traffic to a port on the same slot (where the MACsec source is located) does not have this limitation. |
| ExtremeSwitching 5520 Series Switches | |
| EXOS-30172 | In an Extended Edge Switching stack, an error occurs on slot 2 while loading the structure <ports> after unconfiguring and then restarting the switch. |
| EXOS-30419 | Continuous attempts to authenticate user(s) with Dynamic ACLs (configured via
radius Vendor Specific Attribute (VSA) ID 232 – Extreme-Policy-ACL), which would
exceed the maximum configured or allowed number of ACLs, may cause a crash on the
backup node in a stacked system. The following example log message is an indication this is happening: 1/1/2021 12:00:00.00 <Noti:Policy.SessLmtExcd> Slot-1: Policy 1(policy) assignment by rule [MacSrc |00:00:11:11:22:22|1:1] failed (exceeded blade dynamic acl hardware limits). 1/1/2021 12:00:00.00 <Noti:Policy.SessLmtExcd> Slot-1: Policy 1(policy) assignment by rule [MacSrc |00:00:11:11:22:22|1:1] failed (exceeded blade dynamic acl hardware limits). Workaround: Decrease the number of authenticated users or Dynamic ACLs per authenticated user to avoid this crash. |
| SNMP | |
| EXOS-30775 | ExtremeXOS modifies the OID of an SNMP get-request instead of returning a "No Such Instance" response for extremePethPsePortTable. |
| SummitStacking | |
| EXOS-30060 | In a SummitStack with VPEX enabled, the ELSM state remains down when configured on CB ports. |
| VXLAN | |
| EXOS-29918 | If VMAN CEP egress filtering is applied on a VXLAN underlay or MPLS Network
port, traffic does not go through. Workaround: Run the disable vman cep egress filtering command from the VXLAN underlay port/MPLS network port. |
