- Minimum auto-recovery time reduced for duplicate MAC address detection (ACX Series,
PTX Series and QFX Series)—Junos OS has changed the minimum value allowed for
auto-recovery time for duplicate MAC address detection from 5 minutes to 1 minute. The
auto-recovery time is the length of time that the device suppresses a duplicate MAC
address. Reducing the auto-recovery time allows customers to quickly recover from a MAC
address duplication state. You configure the
auto-recovery-time
option under theduplicate-mac-detection
statement at theedit routing-instances routing-instance-name protocols evpn
oredit protocols evpn
hierarchy.
