Hi i dont see any rspan bugs in your version that are known about anyway , link below , one in earlier version did TAC test with the same version IOS-XE , unless theres a specifc reason you cant you could try a different version , your on the latest and if its a bug it may not have been discovered yet until its passed to the BU to check is it intermittently dropping traffic or its dropping all traffic ? TAC confirmed config is ok yes and the vlans are definitely forwarded between the switches on the trunks etc https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3850/software/release/16-3/release_notes/ol-16-3-3850.html ...

Ok so even though everything looks good from the switch side , when you force a failover either by cli or pulling the plug your HA doesn't fully work and you loose your wireless users connected to the standby switch Is this only happening to wireless users ? is there any switches dual connected to the pair of switches that you could run a constant ping and see if the same issue is seen , it will rule out the wlc , just thinking is it something to do with how the 9k communicates with the wlc when the failover occurs or is it something general to how the 9k is failing over and effects all systems dual homed ...

We started to move to 9ks campus , changing all our 3650s and 3850s out for 9ks moving forward , 45s replaced too coming up soon The reason being we were deploying 4507s and the prices were coming in a lot cheaper for the newer 9400s like 20k a box , then we priced up the edge and seen it was the same couple of grand cheaper a box , we tested them couldnt find any issues that would prevent us from deploying them so we have started moving forward There out couple years now at least so there stable , the difference that pushed us was also hardware spec 80gb uplinks standard module , faster backplane , same IOS-XE architecture were familiar with , the data sheets speak for themselves when you line them up beside current and new models We were also upgrading ACS to NAC/ISE and the newer licenses on 9ks advantage come with user PI and ISE licenes included unlike the 3k series or 4ks so there were a few extra reasons ...

Hi yes the new 9k campus sets are the new switch series and quite stable now too , running same IOS-XE as previous switches 3650s/3850s etc, lately a lot of 2960 series have hit EOL but there is no word yet on the X series , if you are purchasing new equipment  a 9200 would be a better choice than a 2960 , the 9ks are more powerful switches newer technology and no chance of reaching EOL anytime soon   These 2 data sheets show the hardware and feature difference between both series   https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-9200-series-switches/nb-06-cat9200-ser-data-sheet-cte-en.html   https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-2960-x-series-switches/datasheet_c78-728232.html   NO EOL https://www.cisco.com/c/en/us/support/switches/catalyst-2960x-24ts-l-switch/model.html https://www.cisco.com/c/en/us/support/switches/catalyst-2960x-48ts-l-switch/model.html ...
