I have an ASA 5510 and have recently added a second (primary) internet connection and have an older DSL line which I now intend to use as a backup connection. Planning ahead for this, I put the DSL on interface 0/1 and the T1s are on 0/0. Unfortunately, the handy graph on the home page of ASDM is locked to the "DSL-Outside" interface (0/1) and I can't seem to find any way to change it to the "T1-Outside" interface (0/0). Is there any way to do this? (perhaps a command-line incantation?)
It depends on the security level of the interface. The graph will show the interface with the lowest level. If there are 2 interfaces with the same security level then it will go alphabetically.
Please rate if this helps.
