Restrict management access to HTTPS and SSH only

How do I restrict management traffic to HTTPS and SSH only ? I should be able to login to config utility and access via SSH and block all other type of connections. How do I do that ?

Management access is allowed only through https and SSH. You can restrict ssh access in WebUI only to specific subnets using below steps.

 

Login to webui > System > Platform > User Administration > Under SSH IP allow section mention only required subnets.

    Thanks Raghavendra for the info. I don't have a requirement to restrict the subnets from which the device can be accessed.
