How to disable SSH weak algorithm supported

We used Nessus to run security scan on the PA-5220 we are trying out and it came back with the following medium vulnerability:

https://www.tenable.com/plugins/nessus/90317

The remote SSH server is configured to allow weak encryption algorithms or no algorithm at all.

Nessus has detected that the remote SSH server is configured to use the Arcfour stream cipher or no cipher at all. RFC 4253 advises against using Arcfour due to an issue with weak keys.

Contact the vendor or consult product documentation to remove the weak ciphers

 

 

Any idea how to remove/disable the weak ciphers?
