I have the following issue with the management interface of an ASA5520 running version 7.0(7).
I'm currently using two contexts in transparent mode.
The management interface is currently assigned to the admin-context and is physically connected to a cat4500 switch in a management Vlan.
The issue is that I have intermitent communication with this IP address from the 4500 and I just can't explain what's going on, the IP address configured in the management port is not repeated in the vlan and the interface vlan in the 4500 is always UP.
As I explained it is possible to log into the ASA using SSH but the connection is dropped at some point. I also need to upgrade the software version but the tftp session is dropped due to lack of conectivity.
Does anybody have a clue regarding the possible solution?
The adaptive security appliance has a dedicated interface for device management that is referred to as the Management0/0 port. The Management0/0 port is a Fast Ethernet interface. This port is similar to the Console port, but the Management0/0 port only accepts incoming traffic to the adaptive security appliance.You can configure any interface to be a management-only interface using the management-only command. You can also disable management-only mode on the management interface. For more information about this command, see the management-only command in the Cisco Security Appliance Command Reference prsent in the link below:
