Known Issues, Platform-Specific, and Feature Change Requests (CRs)

CR Number Description
ExtremeSwitching X440-G2 Series Switches
xos0069482 On ExtremeSwitching X440-G2 series switches, while using BASE-T optics, changing the default auto-negotiation setting causes link issues.
ExtremeSwitching X690 Series Switches
xos0070154 On Summit X690 series switches, the connector type appears as "Unknown" for FINISAR vendor, 1000T optic with part number "FCLF-8521-3".
xos0068889 Configuring management VLAN in CDP is not reflected in show configuration edp output.
Workaround: Use the command cdp neighbor detail to confirm configuration.

After deleting a port disabled by ELRP from a VLAN, the port is disabled forever.

Workaround: Enable the port manually.
The SSH rekey interval cannot exceed the SSH idle timeout interval. If the SSH rekey interval is greater than the idle timeout interval, rekey does not occur and the SSH session is terminated after reaching the rekey interval.
Workaround: Configure the SSH idle timeout to be less than the SSH rekey time interval.
SSH sessions from Putty to a switch do not timeout based on the SSHv2 idle timeout value set with the configure ssh2 idletimeout command if the value is greater than the "Max Minutes before rekey" value configured in Putty settings.
Workaround: Set an idle timeout using the configure idletimeout minutes command (enabled by default for 20 minutes) on the switch, or set the SSHv2 idle timeout value using the configure ssh2 idletimeout command on the switch, or set the rekey interval in the Putty client accordingly.
xos0068839 Enabling IP-forwarding on an a VXLAN-based VLAN interface should also have fabric enabled. Multicast routing with PIM-DM does not function with fabric-based VXLAN, which relies on the BUM replication method already in place.
