  • Source MAC filtering on aggregated Ethernet interfaces (EX4100 and EX4400 switches)—Starting in Junos OS Release 22.4R1, you can configure source media access control (MAC) filtering on an aggregated Ethernet interface on EX4100 and EX4400 switches. Ingress packets are matched on the source MAC address list that you configure at the accept-source-mac mac-address hierarchy level on the logical interface of the aggregated Ethernet interface.
