xos0058553 On BlackDiamond X8 series switches, in large topology (~2,000 pseudo-wires and lots of LSPs and ILM), disabling all VPLS sessions on switch causes SMAC learning to take longer than usual if the traffic comes from a different pseudowire. Traffic loss occurs during this interval.
xos0058615 ESVT: Loopback port fails to indicate "Link State" of "L". The loopback port is physically looped back. However, if user traffic is in the VLAN, then potentially unwanted traffic can get looped causing issues.

xos0061479 OpenFlow process signal 6 ends unexpectedly on Summit X460 stacks.
xos0060009 Some flows cannot be installed when OpenFlow FDB table is turned on.

When MS Lync application (MSLync 2.0 solution) attempts to install a LYNC OpenFlow flow with action set queue and set field IP DSCP with Hybrid Mode enabled, a OFPBAC_BAD_QUEUE error occurs. The flow is not installed.

The flow is properly installed after rebooting the switch.

xos0059621 Lync should be able to install flows for hybrid VLANs without knowing the VID for those VLANs.
xos0059604 In a stacked environment the Datapath ID changes with every stack reboot. This may cause OneController to go out of sync as the NodeID changes (stale nodes and flows in OneController).
xos0059288 Cannot install multiple XMOD files in BlackDiamond 8800 and BlackDiamond X8 switches due to lack of space.
xos0059160 Sending a flow install with the vlan-id-present field set to false from the OneController causes the flow to fail to install with an ExtremeXOS bad port error message. The flow installs properly by setting the field to true.
xos0059139 OneController uses set_field:0->vlan_vid for strip VLAN action causing an ExtremeXOS error.
xos0058978 Flows with both output port and controller actions cannot be added.
xos0058117 After enabling, and then disabling, OpenFlow globally and on a VLAN with standard mode, you cannot enable learning on the VLAN anymore.
xos0057346 Link flaps occur when optics such as 10/100/1000 Base-T or 100FX is inserted into Summit X460-G2 and X480 series switches.
xos0059579 SFP+ ports do not link up with active optical breakout cable. Cable is identified as not supported and treated as a 3rd-party cable.
xos0059574 OSPF packets larger than 8,192 are dropped even with jumbo frame enabled.
xos0056243 OSPF process ends unexpectedly during frequent route re-calculation caused by switch reboot or master switch fabric module. (MSM) failover or BFD flap events.
xos0058221 Rarely, OSPFv3 process ends unexpectedly with signal 11 when link flaps occur.
xos0059305 OSPF consumes a large amount of memory when a large number of Link State Acknowledgment packets are queued up for transmission.
xos0058994 POE is not delivering power to several model phones when legacy mode is enabled.
xos0060600 EPM process signal 5 ends unexpectedly when creating a new process with a dash in the name.
xos0058683 RIP packets are dropped when another VLAN has a secondary IP address configured.
xos0060103 SNMP walk does not return all VLANs under extremePortVlanStatsTable.
xos0058130 Q-Bridge MIB: On doing SNMP walk for dot1qVlanStaticEgressPorts and dot1qVlanStaticUntaggedPorts for ports in different slots, invalid port number values are returned.
xos0058110 Q-BRIDGE MIB: dot1qPortGvrpStatus and dot1qGvrpStatus should return value as "2" with MVRP disabled globally and at the per port level, but it returns value as "0" which is incorrect as per RFC.
xos0060243 The process rtmgr ends unexpectedly while changing IP address on VLAN when switch is booted with configuration such that an IP route has local or loopback interface address as gateway.
xos0060780 With VRRP enabled, local VLAN's direct route is not installed in hardware after reconfiguring the VLAN's IP address.
xos0058698 Traffic stops egressing after adding the egressing port to some other VLAN that is having PSTag configuration with other ports.
xos0057435 Packets are dropped when learning is disabled in a VLAN when its associated ports are configured with limit learning in another VLAN.
xos0060794 VRRP advertisement interval configuration got changed after upgrading EXOS from 12.6 to 15.4 or above releases. Issue happens only when interval is configured in milliseconds.
xos0053821 IPv6 neighbor advertisements for VRRP virtual IP address uses virtual MAC address as source MAC address instead of switch MAC address.
xos0061222 Gratuitous ARP packets for VRRP virtual IP addresses have ARP sender addresses as physical MAC addresses, instead of VRRP virtual MAC addresses.
xos0058020 When both the HTTP and HTTPS are enabled, only HTTPS works,
