VTY MAC-SA Filter Support
Dell Networking OS supports MAC access lists which permit or deny users based on their source MAC
address.
With this approach, you can implement a security policy based on the source MAC address.
To apply a MAC ACL on a VTY line, use the same
access-class
command as IP ACLs.
The following example shows how to deny incoming connections from subnet 10.0.0.0 without
displaying a login prompt.
Example of Configuring VTY Authorization Based on MAC ACL for the Line (Per MAC Address)
Dell(conf)#mac access-list standard sourcemac
Dell(config-std-mac)#permit 00:00:5e:00:01:01
Dell(config-std-mac)#deny any
Dell(conf)#
Dell(conf)#line vty 0 9
Dell(config-line-vty)#access-class sourcemac
Dell(config-line-vty)#end
Role-Based Access Control
With Role-Based Access Control (RBAC), access and authorization is controlled based on a user’s role.
Users are granted permissions based on their user roles, not on their individual user ID. User roles are
created for job functions and through those roles they acquire the permissions to perform their
associated job function.
