I have no mac addresses defined anywhere in the config, hopefully that's what you're asking?
By the way, these are EX4500 virtual chassis all with 2 members. We are running 12.3R12.4 on 3 out of 4. The other one has 15.1R5.5. This problem with all macs with age 0 happens on both versions. These EX switches are strictly layer 2 devices and all are configured pretty similarly. 2 out of the 4 (on 12.3R12.4) have ages on some mac addresses. I can't figure out why.
Thanks.
