It is way quicker and cleaner to just use the CLI. &nbsp; The CNA may lose connection once in a while and you will not see the correct data and have to constantly refresh. 
 
It also seems quick a few people have this same issue with CNA. &nbsp;I find it way cleaner and quicker to just hit the CLI and have it done cleanly. 
 
Especially if multiple people are working on the devices. 
 
Hope this helps. 
 
Thanks

Ok , but if I need to do it using CNA and no one is connected to the switch except me how i can do it ?

Have you added priv 15 to the user account on the switch...?

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
