CR Number Description
The following log message appears when a subnet is reachable both using MPLS and non-MPLS:
<Warn:Kern.IPv4FIB.Warning> Slot-4: dest 0x0A420000 / 24  nexthop 0xAC11121E: Unable to add route to unit 1, rc Entry not found.  Shadow problem. 
Summit X430 Series Switches
xos0059486 On Summit X430 series switches, optics are not detected after repeated removal and reinsertion of optics when CPU is busy.
xos0064084 In Summit X430 series switches, the command show power details displays fan status as "empty".
Summit Series Switches
xos0059007 QSFP+ to SFP+ adapter support is added to work with all optical SFP+ transceivers with the exception of LRM and passive copper direct attach cables.
xos0059484 Gigabit Ethernet compliance value is shown as "UNKNOWN" for BXU/D optics. Also, DDMI values do not appear. Media Type appears as "NONE" in show ports configuration command.
xos0059508 Link does not come up when 1G BX U/D optics are inserted into 10G SFP+ ports.

Workaround: Configure the port for speed 1,000 with auto-negotiation “on” using the command configure port <> auto on speed 1000 duplex full. For Summit X670V switches, remove and then re-insert the optics. For all Summit switches, except the X670V, the corrected behavior persists even after rebooting. For Summit X670V switches after rebooting, the transceiver must be removed, and then re-inserted.

xos0062570 In SummitStacks, executing the command enable sflow ports all enables sFlow inappropriately on stacking ports.
xos0062821 ACL rules installed are not mapped to single virtual group even though ACL action-resolution mode is highest-priority.

 10/03/2015 18:15:15.47 <Info:HAL.Card.Info> Switch is operational
Summit X450-G2 Series Switches
xos0060129 On Summit X450-G2 series switches, 10/100/1000BASE-T SFP+ optics do not link to similar optics when in the SFP/SFP+ ports. They do link or partially link when connected to a regular triple speed copper port.
Summit X460 Series Switches
xos0063206 Cannot add L2 entries in hardware due to a full L2 table caused by hash collisions.
xos0063595 On Summit X460 series switches, the command to configure stacking ports does not show the native option.
xos0063948 Clearflow delta values are randomly not calculated properly.
Summit X460-G2 Series Switches
xos0060018 With a 0.5M, 40G QSFP MOLEX passive copper cable inserted, disabling the port where the optic is inserted, rebooting, and then enabling the port, the port stays in the ready state and doesn't come up as enabled.

Workaround: Remove and re-insert the optics. The port then comes up as enabled.

xos0061486 Combo ports have unsupported autonegotiation and half-duplex settings.

xos0062913 On Summit X460-G2 series switches, copper combo port does not advertise its flow control capabilities to peers.
xos0063495 Policy authentication fails when RADIUS request queue has stale entries.
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.

Summit X670 Series Switches
xos0060656 Link does not come up when 1G BX U/D optics are inserted into 10G SFP+ ports.

Workaround: Configure the port for speed 1,000 with auto-negotiation “on” using the command configure port <> auto on speed 1000 duplex full. For Summit X670V switches, remove and then re-insert the optics. For all Summit switches, except the X670V, the corrected behavior persists even after rebooting. For Summit X670V switches after rebooting, the transceiver must be removed, and then re-inserted.

xos0061260 When learning a large number of BGP routes, routes are learned first in route table, rather than LOCAL-RIB. No routes are learned to RIB until all routes are learned in route table. All prefixes are learned in route table, and only then are all prefixes are learned to LOCAL RIB.
xos0062009 In BlackDiamond 8800 series switches with XL modules, clearing FDBs when there is a loop causes the FDBs to lose synchronization across slots or switching units.
xos0062535 On BlackDiamond 8900-10G24Xc I/O modules, packets are dropped by ACL rules with "redirect-port-list" action.
