Workarounds: Do not use port 1 for PTP.

CSCwc03518

Headline: N3K-C3408-S crash due statsclient and port_client process crash with 100G link flaps.

Symptoms: N3K device unexpected reload by Reset Requested due to Fatal Module Error, Service: port_client hap reset and  statsclient hap reset.

Workarounds: None

CSCwc05779

Headline: MCN-79278 - Innolight QSFP-100G-ER4L-S - Nexus 3000 - Utopias - Transceiver Details Errors

Symptoms: DOM output is not showing properly on Nexus 3400There may also be false positive syslogs for high temp/voltage...

Workarounds: None

CSCwa71023

Headline: N3164 : No data (stack\core\NMI) generated for Watchdog Timeout

Symptoms: Nexus 3164 reloads and the reset-reason is set as  'Watchdog Timeout'.No other information/data is available in logs to conclude what caused the watchdog timeout.

Workarounds: There is no workaround at this time.

CSCwb34359

Headline: N3232C - ICMPv6 Traffic Incorrectly Forwarded to CPU

Symptoms: A Nexus 3232C Series Switch will erroneously punt ICMPv6 traffic to the CPU, causing legitimate ICMPv6 traffic to be dropped in the Control-Plane Policer.

Workarounds: None.

CSCvx51159

Headline: Nexus 3548 - Boot times increased after upgrade to 9.3(6)

Symptoms: After upgrade from 9.3(5) to 9.3(6), boot times have increase from 20-40 seconds.

Workarounds: None.

CSCwc08268

Headline: Nexus all (N3K/N9K) GLC-GE-100FX V03 Transceiver Compatibility

Symptoms: When a Nexus 3000 or 3500 is using a SFP-100FX-GE Cisco version V03 the link will come up fine; however, no traffic will pass on the link. No CDP information is shared over the link. Testing with ICMP traffic also fails even though the switch shows the link in an "up" state.switch# sh int e1/3 transceiver detailEthernet1/3    transceiver is present    type is SFP-100FX-GE    name is CISCO-OPLINK    part number is <null>    revision is 01    serial number is <null>    nominal bitrate is 100 MBit/sec    cisco id is 3    cisco extended id number is 4    cisco part number is 10-2019-03    cisco product id is GLC-GE-100FX    cisco version id is V03

CSCvz75894

Headline: N9500-R/N3600-R hardware application counters may get corrupted

Symptoms: N9500-R/N3600-R running 9.3(x) version of converged code may experience hardware counter corruption causing specific application counters to show incorrect information.

Workarounds: Reload will clear the issue but it can resurface
