BlackDiamond 8800 Series Switch
PD4-1865375583,
PD4-1854613879
On a BlackDiamond 8800 series switch, multicast packets are sent directly to the CPU
instead of being forwarded in hardware.
PD4-1544795181 On a BlackDiamond 8800 series switch, the aggregate number of user created VRs and
VRFs bound to ports of an I/O module are limited to the supported number of VRs for
that module. Each newly created user VR or VRF is internally assigned an increasing
identifier starting with 3. Ports bound to user VRs and VRFs must support the number of
VRs equal to the internally generated identifier minus 1 for the VR/VRF or traffic is
dropped. Create VRs and VRFs bound to ports of lesser scaling I/O modules first.
PD4-1678739937,
PD4-1655256488
BlackDiamond 8800 series switches report "conduit failures" during bootup if the switch is
configured with diffserv replacement enabled for more ports, as well as diffserv
replacement mapping.
PD4-1584522573 When running the run msm failover command on a BlackDiamond 8800 series
switch with an MPLS configuration, the following error may be displayed.
MPLS bcm_mpls_port_add failed
PD4-1637395977 On a BlackDiamond 8800 series switch, the following error message may be logged
when attempting to delete VPWS instances from a configuration.
Failed to locate a VPLS peer for label 0
Workaround: Delete the VPWS/VPLS and the VLANs separately, or introduce a small
delay (1 second) between deleting the VPWS/VPLS and deleting the VLAN.
BlackDiamond 12800 Series Switch
PD4-1820555211,
PD4-1083288117
Disabling and re-enabling a port that is configured for 100 Mbps full duplex with an
attached dual speed SFP (100FX/1000LX) results in connectivity issues.
PD4-1667994741 When terminating or starting process IdMgr gracefully, the process crashes with signal
11, the switch reboots, and IdMgr role configuration is corrupted.
BlackDiamond 20800 Series Switch
PD4-1633907245 A primary MSM may fail and reboot because of a dual master MSM while downloading
and installing a new image using a larger number of routes and traffic. This issue is not
reproducible using ExtremeXOS 12.5.2 software.
PD4-1380031199,
PD4-1199314951
After an I/O module hotswap, the show fdb command output does not show the FDB
entries learned on particular slots.
PD4-1678739963,
PD4-1440442939
A BlackDiamond 20800 series switch forwards traffic with the wrong MAC address after
receiving a gratuitous ARP request.
PD4-1648440591 IPv6 traffic stops forwarding on a BlackDiamond 20800 series switch after load sharing is
disabled and enabled.
PD4-1648470710 RIPng convergence is not working correctly on a BlackDiamond 20800 series switch if a
trunk port is removed and a new port is added.
PD4-1571496939 Establishing 255 ISIS adjacencies in multi-topology mode on a BlackDiamond 20800
series switch causes a HAL crash.
Summit Family Switches
PD4-1662849321 IdMgr and HAL crashes with signal 11 occur after running UPM profiles for
identity_detect, identity_undetect, identity_role_associate, and identity_role_disassociate.
This issue is not reproducible in ExtremeXOS 12.5.2 software.
PD4-1840662158 Clients are not able to reach each other through a tunnel after running the clear fdb
command or a link flap occurs on an MPLS cloud (LSR).
PD4-1606154901 Process BFD crashes on a Summit X460 switch after running the show bfd session
command when scaling higher than 100 sessions.
Workaround: Do not configure more than 75 sessions with an MPLS client.
