Framed MTU RADIUS Authentication Failed on WLC 9800

[diegoarmando]

 We are implementing a WLC 9800 with RADIUS authentication, but we need to change the Framed MTU to 1300, default set is 1485

on WLC 5508 it was possible in RADIUS authentication server global configuration,

does anyone know where it can be modified in the WLC 9800?

Thanks!

Couldn't find anything in the docs, besides the documentation that this feature was added in 8.1 for older WLC.

You might want to open a TAC, it's possible that this isn't supported yet.

                                                                - Can you do it on the cli with :

(Cisco Controller) > config radius auth framed-mtu 1300

that command is for WLC 5508, im looking for a WLC 9800,

Thanks!

 - On CLI use : radius-server attribute ?

                        Check if any options returned relate to framed mtu settings.

We opened a case in TAC and they mention that it is not yet supported in the 9800 version

Thanks for you support

Just came across this post while searching for some info regarding Framed-MTU on 9800:

https://www.cisco.com/c/en/us/td/docs/wireless/controller/9800/17-6/deployment-guide/Configurable_Framed-MTU_on_Cisco_Catalyst_9800.html

Supported from 17.4 code onward.

Closing the thread!
