  • 1.  Aruba 3810 public key install

    Posted Mar 11, 2026 12:18 PM

    Has anyone been able to get their public key to attach to their username in the Aruba 3810? Every time i tried i kept getting "invalid key" despite using the exact same public key I have in my other switches. Also, for some weird reason the switch will accept "ssh-rsa" as a username but not my actual username when i input "Ip ssh public-key manager username <my username>"

    Are your other switches also AOS-S/PVOS switches (same operating system)?

    Is the 3810 on the same firmware version?

    My other switches are 8320s so a different OS and command structure.

    update: They command took but says "invalid key" here is an example output. See below



    ip ssh public-key manager "ssh-rsa xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" username johndoe

    I've personally never successfully installed a user's public key on a AOS-S device, but found if the key is not accepted, you should make sure the key is of type RSA (which your key seems to be) and if it doesn't work try a 2048 bit key. The following command is at least accepted in my switch:

    sw00(config)# ip ssh public-key manager username admin "ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC9p1kI14UO1JhxEEBoXfaOz6Ret2BYRBrw7+IeQ2pkKd9SeCZmUQwnv+/LCy8NnQNAIar4QhTvckyGpVnfuHh3xoUgpGZKJF4a/5Ge88+jmMYBo/jo0uyri0MLsra3Lnmj55QlZ93MsbpLZW7Zf6yrUZ+MJWccgkwwH/u16h2kpq7C1Q7HYClRJsHmebnr36L66B5GX/5WKoPI2IWKJuhTDMzs+jkk6t2oYWZd3in/kGUdn2RSRlks0mzEi9i1urtoZzGeojYMTX4YFjzeI2CgXDj8X0ZD9R8DoGlWs/J4TTz20lujqYiWcuFsHygNRPNMUOYnvkOQKs
NonNTg/84D hermantest@ubuntu-server"

    I swapped the key and the username, but that may not be needed. Also I think there should be a name a the end of the key-line, so "ssh-rsa <key> <name/id>". Hope this works for you as well.
