L3 traffic is not distributed among LAG ports if a static FDB is configured on the LAG
port of a BlackDiamond 20808 switch.
PD4-751294438 A PVLAN subscriber VLAN side device cannot reach a network VLAN side device.
PD4-807083163 Running an MM failover multiple times on a BlackDiamond 20808 switch may result in
IPv4 packets being forwarded in software.
PD4-815641157,
PD4-779588691
An FDB process crash occurs after enabling an LACP LAG.
PD4-826609208,
PD4-805055301
When a single port is configured for WAN PHY, the show configuration vlan or
show configuration commands display all ports having a WAN PHY configuration.
PD4-870848448,
PD4-852419538
The link on a 10GE port remains active when the Tx fiber is removed from a
BlackDiamond 20808 switch while the Rx fiber remains connected.
PD4-756309458 When configuring remote mirroring using a BlackDiamond 20808 switch as the
intermediate or destination switch, the remote mirroring port does not receive IP multicast
traffic if the monitor port of the source switch is tagged. The traffic is dropped in the
transit VLAN.
Workaround: Configure the monitor port of the switch as an untagged port so that IP
multicast traffic will pass through the transit VLAN.
PD4-872419991 After running the run diagnostics extended command on slot1 of a BlackDiamond
20808 switch, slowpath traffic is no longer forwarded to the CPU on slot 1.
PD4-798727801 A PSU is used in slot 4 and 5 in a BlackDiamond 20808 chassis, but ExtremeXOS
software or the MM identifies the PSU in slot 4 only as “power failed." The PSU in slot 5
is operational based on an LED inspection, but ExtremeXOS does not recognize the
PSU.
PD4-1023187021,
PD4-963878819
When a BlackDiamond 20808 series switch runs an MM failover, or a failover is
occurring due to a process failure, too many SNMP traps are generated.
PD4-1017565804,
PD4-964664834
The following logs are displayed in the master MM when the backup MM is becoming
active and the master MM tries to checkpoint the PVLAN data:
<Erro:DM.Error> MM-B: hal: cannot create msg DM_MSG_CHKPT_DATA
c10b 235c 0x10bbcd00
<Crit:DM.Critical> MM-B: hal Cannot create msg DM_MSG_CHKPT_DATA
of size 9052 (too big)
Summit Family Switches
PD4-811997761,
PD4-821706998
In some scenarios, the following is seen on a fully loaded SummitStack with non-
Extreme optics:
pibConduitRcvMsg: no magic number (0x0) slot number 6, tcp port
5003 [socket buffer length 8,Message version 0, opcode 0, length
0]
This is followed by a HAL process crash. A consistent flapping, receive loss of signal
condition, can fill up the conduit queues.
PD4-493683561,
PD4-449901506
Disabling multicast flooding on a port may result in ARP requests being blocked.
PD4-1168199981,
PD4-935277568
The error SFP I2C read/write failure is seen after disabling a port, and saving
and rebooting a 10/100/1000BASE-T SFP module.
PD4-843338091,
PD4-772840781
On a Summit X450a series switch, it takes ARP approximately 8 to 190 seconds to
resolve after an ESRP failover when the switch is experiencing heavy traffic.
PD4-1062792957,
PD4-997419038
When dot1x and MAC-based authentication are both enabled on a port and a user is first
authenticated using MAC-based authentication, while dot1x authentication is also
running, the response from the RADIUS server is dropped.
PD4-983612803,
PD4-970731498
XGM2-2bt modules keep reloading the same firmware to one of the ports when the
switch reboots.
