The following are new open issues for supported features found in ExtremeXOS 21.1.5-Patch1-5.

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

CR Number	Description
General
xos0067463	Traffic does not distribute across LSPs and LAG after enabling L2VPN sharing feature.
xos0062584	The command configure web http access-profile is missing the option access-profile.
xos0062966	When rendezvous point receives (*, G) join, and it has (S, G, RPT) entry, the entry should be converted to (S, G), and (S, G) join should be sent upstream. However, sometimes wrong assert is triggered and this new entry is dropped after a minute, resulting in complete traffic loss. Workaround: Disable, and then re-enable PIM.
xos0063247	Duplicate packets occur during MLAG link recovery when LACP is used for load sharing.
xos0063396	While enabling 1G links, unexpected link-down PDU is received in EAPS master.
xos0048715	IPv6 ECMP works for hardware-forwarded traffic, but does not work for slow-path traffic. Workaround: Either use BFD to keep all router neighbors alive, or configure static neighbors and static FDB entries for all router neighbors. BFD is the preferred method.
xos0062399	IPv6 BFD session for OSPFv3 flaps after disabling, and then enabling VLAN port.
SummitStack
xos0062386	With BGPv6, after port flap or failovers, some peers go into idle state.
xos0061909	Creating an IPFIX mirroring instance to a monitor port, deleting the mirroring instance, and then recreating it again to a different monitor port, causes the following error message (similar to the one below) to appear, and IPFIX mirroring does not work: <Erro:HAL.Mirror.Error> Slot-1: Failed to create mirroring destination for slot 2, unit 9 Entry exists Workaround: If the error appears in the log, disable and delete the mirror instance, and then add it back again.
ExtremeSwitching X620 Series Switches
xos0062636	Unexpected link switchover behavior occurs when exchanging copper and fiber cables on ExtremeSwitching X620 combo ports. Workaround: When 10G combo ports are used at 1G for redundancy between fiber and copper, then set the preferred medium to copper (configure ports port_list preferred-medium copper), otherwise sometimes the copper link might not come up. When 10G combo ports are used at 10G for redundancy between fiber and copper, then set the preferred medium to fiber (configure ports port_list preferred-medium fiber), otherwise sometimes the copper link might not come up.
xos0062620	For ExtremeXOS 21.1, do not use copper DAC cables for stacking on ExtremeSwitching X620-16T switches.
Summit X670-G2 Series Switches
xos0063170	On Summit X670-G2 series switches, greater EAPS convergence time occurs with multiple VLANs (1,000 protected VLANs).
xos0063492	When a 1G port (SX/BASET) is used as a loopback port for mirroring to a port-list, the port does not come back to active state after disabling mirroring.
Summit X460-G2 Series Switches
xos0063811	Summit X460-G2 series switches with ExtremeXOS 15.6 through 21.1, have the following limitations for SyncE input reference frequency: Network clock does not lock with input SyncE source port 52 (both at 10G and 1G speed) on all 48-port models (X460-G2-48t, 48x and 48p). Workaround: For SyncE input at 10G, avoid port 52. When the 10G ports operate at 1G speed, the network clock does not lock. Models with Ethernet BASE-T or Power over Ethernet (PoE) ports may lock on initial configuration, but do not lock after a save and reboot. Workaround: For SyncE input at 1G, use a 1G port, not a 10G port.
xos0063412	CFM fault not detected locally after disabling CCM for hardware Down MEP.
ExtremeSwitching X440-G2 Series Switches
xos0062236	EEE becomes disabled on combo ports after peer ports are disabled, and then enabled.
xos0062773	After switch boot up or restart of process dot1ag, 95% CPU utilization occurs with 32 UP MEPs (maximum value).
xos0062895	On ExtremeSwitching X440-G2 stack, process nettools fails to start after rebooting with DHCPv6 client enabled. Switch reboots repeatedly and reports the following errors: 10/20/2015 11:31:06.45 <Erro:EPM.crash_rate> Slot-1: Process netTools exceeded pre-configured or default crash rate 10/20/2015 11:31:06.45 <Erro:DM.Error> Slot-1: Process netTools Failed 10/20/2015 11:31:06.45 <Erro:DM.Error> Slot-1: Process netTools Failed 10/20/2015 11:31:06.45 <Erro:DM.Error> Slot-3: Node State[4] = FAIL (Not In Sync) 10/20/2015 11:31:06.46 <Erro:DM.Error> Slot-1: Node State[4] = FAIL (Process Failure) 10/20/2015 11:31:06.61 <Crit:NM.NodeStateFail> Slot-1: Slot-3 has failed for the reason of "Not In Sync".
xos0062899	DHCPv6 client remains in initializing state after disabling, and then enabling, the port in the relay switch. Workaround: Restart process nettools, or disable, and then enable, DHCP client.
xos0063678	In ExtremeSwitching X440-G2 stack, rebooting backup slot with CFM 32 Down MEP configuration times out with the following errors: Error: This command is not permitted on nodes that are not active 02/16/2016 15:16:34.06 <Warn:HAL.Stacking.Warning> Slot-1: Timed out waiting for 1 reboot replies. 02/16/2016 15:16:34.06 <Warn:HAL.Stacking.Warning> Slot-1: Timed out waiting for 1 reboot replies.
Summit X450-G2 Series Switches
xos0063008	In Summit X450-G2 stack with mirroring configuration, boot up times out (after 300 seconds) while waiting for configuration checkpoint save operation to finish (FDB is still not saved).
BGP
xos0060641	When BGP is administratively shut down, it does not send notifications to peers.
xos0063778	If an applied BGP import policy is edited such that previously permitted routes are now denied, the BGP RIB (show bgp routes command) still shows the newly denied route(s) as active. The routing table is, however, updated correctly to reflect the new policy.
xos0063698	A BGP route is not replaced in the routing table by a new instance of the same prefix and length containing a different metric value. This condition can occur if an applied BGP import-policy file is edited to modify the route metric.
MPLS
xos0062996	VPLS: Traffic is not forwarded to service port (VLAN-tagged port) when CEP egress filtering is enabled on it. Workaround: Disable CEP egress filter.
NetLogin
xos0062680	Switch fails to send Radius accounting message for dot1x user after clear netlogin state port <portNumber> command.
Optics
xos0062092	For Finisar LX-SFP optics, RxPower appears as "inf" instead of displaying correct value in the output of the show port transceiver information detail command.
SNMP
xos0062492	Traps having tabular variables as varbinds should include the instance along with the tabular OID.
xos0062523	SNMP traps for overheat and negative temperatures incorrectly report detected problems.
xos0062525	extremeEdpNeighborAdded/extremeEdpRemoved traps varbinds need to include the instance along with the OID.
xos0062527	The varbinds of extremePowerSupplyGood, extremePsuPowerStatus traps need to include the instance along with the OID.
