Resolved Issues

Bug ID	Description
CSCwb30246	Headline: N9500-R/N3600-R CoPP incorrectly matches fragmented UDP packet with UDP PTP port payload as PTP pkt Symptoms: PTP CoPP class shows drops. Workarounds: N/A
CSCwb73231	Headline: N9000/N3100/N3500 may be sending out of spec PTP messages with SourcePortID equal zero Symptoms: Nexus PTP messages rejected by 3rd party PTP device. 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 Workarounds: Utilize a SFP-100FX-GE Cisco version V02 transceiver if possible
