ASDM can be run as a Java Web Start application dynamically downloaded from the ASA flash memory. This allows the administrator to configure and monitor the ASA device. In addition, ASDM can be downloaded from flash memory and installed as an application on the host. This approach allows administrators to configure and manage multiple ASA devices using ASDM.ASDM requires some minimal configuration to communicate with a management interface over the network. The management interface, in turn, is dependent on the ASA model. CiscoASA 5505: The management switch port can be any port except Ethernet0/0.
