Welcome banner is not displayed

[Yannick Champs]

Hi,

my host config is simple howewer, the login banner is not displayed with Cisco IOS XR and NX-OS.

        host IPv4_world {
        address = 0.0.0.0/0
                welcome banner = "\n WARNING !!\n\n Network ACCESS is RESTRICTED and LOGGED  !!\n\n"
                key = 123456
        }

I noticed this as well in our environment and, unfortunately, I think it's just a shortcoming with the NX-OS platform. I don't have any IOS-XR to test or I would. NX-OS only supports motd and exec banners and doesn't appear to honor the banners provided by TACACS. I have both welcome and motd banners sent via TACACS and NX-OS is not displaying either. 

If anyone has or finds a workaround, I'd love to hear it, but a quick Google search suggests this is just the way Cisco chooses to be :/

Kindest Regards,
