Hello,

 

to my best knowledge, the 3850 does NOT support NAT. The commands are available, but don't apply to the 3850.

Unless there has been a change that I'm unaware of, Cisco switches do not do NAT. This feature is only available in routers and firewalls.

Hello @katheer4u ,

this is one of the results of unified CLI parser in IOS XE the commands may be present, but a Cisco 3850 does not support NAT.

 

NAT is supported in Catalyst 6500, 6800 and likely on C9500 or C9600 and on routers and firewalls as noted.

 

Hope to help

Giuseppe

Some version of 16.12.X supports NAT on the 9300:  CSCvp78589

Catalyst 9k switches will support NAT starting with 17.X.X.

Hi 

Perhaps this is an old  post but i want to confirm that the c3850 supports NAT 

Hello,

 

NAT is not available on the 3850. I think the commands are there, but the functionality is not.

It was tested today and it works fine , also you can see the nat transaltion table and ofcourse that traffic flows 

The code that i have on the switch are 3.06.06E

 

Hello,

 

I wasn't aware that it works with that code ! Good to know, thanks for sharing.

It is the code i have tested

Glad that i helped for feature tests
