True but dynamic mac addresses will still age out either way, it would just be a matter of how quickly if you can't bounce the IX port or get some administrative assistance to manually the flush the MAC entries on your IX port.

Once the dynamically learned old mac address ages out the new one could be learned or perhaps as soon as the interface goes down the dynamically learned mac address is flushed depending on how it works on Junos. > > > > -----Original Message----- > From: Owen DeLong <[log in to unmask]> > Sender: MICE Discuss <[log in to unmask]> > Date: Fri, 23 Dec 2011 09:24:03 > To: <[log in to unmask]> > Reply-To: MICE Discuss <[log in to unmask]> > Subject: Re: [MICE-DISCUSS] New Switch Proposal > > What is the perceived benefit of doing this? The down-side is that whenever anyone has to replace a line card or do an equipment swap, they need to coordinate with someone who can update the port security on the switch. Worse, they need to remember that's an issue at the time or figure it out through a (not terribly convenient) troubleshooting process. > > Owen > > > Sent from my iPad > > On Dec 23, 2011, at 4:23 AM, Jay Hanke <[log in to unmask]> wrote: > > > I have purchased a new EX 2200 switch for the Mankato Networks rack. > > The new switch will be dedicated and will enable traffic stats for > > those connected to my switch. > > > > As a trial, I plan to enable port security on the downstream access > > ports limiting the port to one learned mac-address.
