Table 1. Open Issues, Platform-Specific, and Feature Change Requests (CRs)
CR Number Description
General
xos0048715 IPv6 ECMP works for hardware-forwarded traffic, but does not work for slow-path traffic.

Workaround: Either use BFD or ping protection to keep all router neighbors alive, or configure static neighbors and static FDB entries for all router neighbors. BFD or ping protection are the preferred methods.

BlackDiamond 8000 Series Switches
xos0063621 After 5 million internet routes are received from an upstream peer, BlackDiamond 8000 series switches experience a link flap, and then CPU utilization goes up to 78%.

Workaround: Flush and relearn routes.

SummitStacks
xos0063739 On E4G-400 and Summit X440 stacks, with 256 Down MEPs, issuing the command restart process dot1ag generates the following error:
 <Erro:cm.sys.actionErr> Slot-2: Error while loading "maintenancePoint": MP 12 Creation Failed due to HAL problem.
xos0064105 On first-time boot up without any configuration on Summit X670v/X480 stacks, backup and standby nodes do not come to operational state and the following error message appears:
04/13/2016 06:04:02.95 <Erro:HAL.Port.Error> Unable to get media type from slot 2 port 41 error -1
 04/13/2016 06:04:02.95 <Erro:HAL.VLAN.Error> failed to setup qosprofile bandwidth port 2:41 unit 9 port 41 qos 0 minbw 0 maxbw 10000000 (Conduit failure)
 04/13/2016 06:04:02.95 <Erro:HAL.VLAN.Error> failed to setup qosprofile bandwidth port 2:41 unit 9 port 41 qos 1 minbw 0 maxbw 10000000 (Conduit failure)
 04/13/2016 06:04:02.95 <Erro:HAL.VLAN.Error> failed to setup qosprofile bandwidth port 2:41 unit 9 port 41 qos 2 minbw 0 maxbw 10000000 (Conduit failure)

Also, all slots are continuously rebooting, except master node. Eventually, master and backup come to "in sync" state automatically, and then standby nodes go to "present" state instead of "operational" 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 an error message, similar to the one below, to appear, and IPFIX mirroring does not work:
Erro:HAL.Mirror.Error&gt 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.

Summit X450-G2
xos0064736 During severe congestion on Summit X450-G2 stacks, master slot reboots due to EPM watchdog expiration from memory depletion and stuck kernel.
