Upgrade to switch 3850

[abdielmoyano]

Hi everyone,

      I have to do an upgrade a stack of 2 switches 3850-48T-E version 16.6.1, because it has a bug of memory leak (CSCvh89372), but I'm not sure about which image to install, because I see different recommendations.

1) Bug documentation (https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvh89372?referring_site=cisco_cli_analyzer): indicates this list of known fixed

Everest-16.6.4

16.9.1

16.8.1

16.6.4

16.3.6

Fuji-16.9.1

Fuji-16.8.1

Denali-16.3.6

16.9(0.58)

16.8(0.209)

16.6(3.15)

16.3(5.111)

2) Cisco Suggested by Hardware (https://software.cisco.com/download/home/284455434/type/282046477/release/Fuji-16.9.2?i=!pp)
Denali-16.3.7(MD)

Everest-16.6.5(MD)

3) Another Cisco suggestion (https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-3650-series-switches/bulletin-c25-737420.html)

Everest-16.6.4a

I don't see any match between these three options. Any idea?

Also if you run DHCP snooping and/or ARP inspection device tracking will be enabled on all ports including your uplinks in 16.x. You might want to turn it off on your trunk links.

Hi
its also important what image your coming from , you need to be in install mode to upgrade to that code so you may need to convert current setup first from bundle if its operating like that
