Example of Configuring VTY Authorization Based on Access Class Retrieved from the Line (Per
Network Address)
Dell(conf)#ip access-list standard deny10
Dell(conf-ext-nacl)#permit 10.0.0.0/8
Dell(conf-ext-nacl)#deny any
Dell(conf)#
Dell(conf)#aaa authentication login tacacsmethod tacacs+
Dell(conf)#tacacs-server host 256.1.1.2 key Force10
Dell(conf)#
Dell(conf)#line vty 0 9
Dell(config-line-vty)#login authentication tacacsmethod
Dell(config-line-vty)#
Dell(config-line-vty)#access-class deny10
Dell(config-line-vty)#end
(same applies for radius and line authentication)
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
