Prior to EOS 4.20.5, port channel min links feature evaluated minimum links in the following scenarios:

Previously, EOS only supported the two-step variation of the transparent clock as described in the IEEE 1588 Specification. In this release, we now support one-step end-to-end transparent clock on certain platforms.The main advantage of a one-step end-to-end transparent clock is that all PTP packets are completely handled in the forwarding plane, whereas in the two-step variation, PTP messages need to be handled in the control plane. This removes scaling limitations such as packet drops due to high packet intervals and reduces CPU utilization.

This feature removes an ARP entry when the physical port, on which the ARP entry's MAC address is learned, goes down. This feature applies only to dynamic ARP entries, not static ARP entries. In addition, if the physical port, which is down,

This feature adds support for "sequential" processing of route-map 'set ext/community' clauses. This feature is enabled via a configuration knob and there is no change in behavior without enabling this knob. The default route-map processing behavior can be summarized as "add then delete".
