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.
PD4-624062541 Jumbo frames are not mirrored to monitor ports on Summit X650-24t switches when
one-to-many mirroring is configured.
PD4-841960995 Running diagnostics on a Summit X450a-48t fails with the following error:
Loopback Phy Fiber : Make Connection Failure on unit-[0] port-
[24] Last
PD4-918730862 Traffic on ports greater than or equal to 28 are not flooded out to stacking ports.
PD4-911150985,
PD4-911212165
Changing L3 adjacency between trunked and non-trunked ports causes traffic to be
forwarded incorrectly.
PD4-899256065,
PD4-899256073
On a Summit X650 switch, sending two 9,000-byte 800 Mbps streams to a single 10G
port fails to trigger flow-control.
PD4-863357932,
PD4-788067297
Multicast traffic is not forwarded after rebooting a standby switch in a stack.
PD4-847610713,
PD4-805737496
A Summit X450 switch only supports 511 LPM routes.
SummitStack
PD4-1147158707,
PD4-1036384285
SRP port utilization is temporarily shown as high on a slave switch after power cycling.
PD4-937401531 Enabling mirroring on a 512 G stack running the latest 12.3.3.5 image in default
standard mode, mirroring works properly. However, if you reset the stack to enhanced
mode, and then back to standard mode, mirroring does not work correctly.
PD4-790755381 Two of the four stack ports in a Summit stack are shown as blocked even though none of
the ports are in the stack.
