ASA Switch Media Type

[joe.ho]

Hi,

I am switching a switch connecting to the ASA5550 tomorrow. My current switch is using fiber connecting to the ASA. The new one only support copper. If I switch between fiber to copper on the ASA (change media-type command on interface) will it cause a down time? I have VPN tunnel on the ASA and don't want the session to reset.

Thanks for you help in advance.

Joe

Think about your question in terms of the OSI model. A media change is a Physical layer and DataLink layer change. All upper layers depend on those two lower layers. There should be no question this will interrupt services.

So you need to schedule your down time and plan ahead, including how to back out in case it fails.

That sounds reasonable. Thanks for the respond.
