MAC addresses per port

‎07-19-2016 11:12 PM

Hello, can anyone please tell me as to how many MAC addresses can be learned per port on EX switches, Is this figure different depending on the EX switch model, if so I would like to know for EX3300,3400,4200 and EX4400. I wasn't able to come across this info in the data sheets

Please refer this link


Maximum number of MAC addresses—You configure the maximum number of dynamic MAC addresses allowed per port. As soon as the limit is reached, incoming packets with new MAC addresses are dropped. The MAC limit value in the EX-series switch default configuration is five MAC addresses.



Mark as accepted solution if find useful.

He's not asking how to configure max allowed per port, he's asking what the maximum learned can be per port.


Mannan I don't think there is a per-port limit that is less than the global but your SE can probably tell for sure for the models you list. I'm able to generate the maximum number of addresses on a single port on an EX2200.
