Open Issues, Known Behaviors, and Resolved Issues
ExtremeXOS 12.4.1 Release Notes
68
PD3-126650411 A stackable system with two or more nodes may experience random VRRP master/backup
flapping issues after an MSM failover when configured with the maximum 128 VRRP
instances using the minimum advertisement interval of 100ms and maximum tracking
entries.
PD3-209191768 After running the disable port all command on a SummitStack, some port LEDs
may sometimes light green even though ports are not up.
PD3-204744742 IPv6 neighbor-discovery in a management VLAN in a SummitStack resolves to the node
address of the stack master, instead of the stack MAC address.
ACL
PD4-722565430 IPv6 ACL address masks are not working correctly after rebooting a switch.
PD4-750014887 If a failover occurs during a “refresh policy” the HAL process dies on a new master MSM.
Workaround: Avoid performing a policy refresh if switching from one MSM to another.
BGP
PD3-209442785 Static multicast routes are not exported using MBGP. However, a static unicast route can
be exported using MBGP.
CLEAR-Flow
PD4-278443631 CLEAR-Flow commands display on platforms that do not support this capability, including
the Summit X150, X250, X350, and X450e series switches, as well as BlackDiamond
8800 non-c-series switches.
CLI
PD3-57182431 For the incoming traffic with alignment errors, the "RX Align" counter in the output of the
show ports <port number> rxerrors command is not incremented. Instead the
"RX CRC" counter is incremented.
EAPS
PD4-749215481 Disabling the EAPS master primary port when there are no other ports configured on a
protected VLAN will cause a disruption of L2/L3 multicast traffic.
Workaround: Enable loopback on all EAPS protected VLANs.
PD4-471892924 Restarting the EAPS process on a controller generates the following error messages on a
console, but does not impact switch performance.
BD-8806.80 # restart process eaps
Step 1: terminating process eaps gracefully ...
Step 2: starting process eaps ...
Restarted process eaps successfully
BD-8806.81 # ERROR:VmgrProtocolIfRegister protoId:0 numIf:1
ERROR:VmgrProtocolIfRegister protoId:0 numIf:3
ERROR:VmgrProtocolIfRegister protoId:0 numIf:1
IP Routing Protocols
PD3-132508261 When issuing the enable jumbo-frame port all command on a BlackDiamond
8800, the MTU size for the VLAN is not configured. Sending 5,000 byte traffic works
correctly. However, if you disable jumbo-frames on the egress port the error message
Packet too big is displayed.
Mirroring
PD3-79867211 If you create a load sharing group (trunk), then enable mirroring to a port, the software
allows you to add the mirroring port to the load sharing group.
