Table 5. New in 10.5.2.1Releases and document revisions.
Revision	Date	Feature	Description
A01	2020-11-23	Synchronous Ethernet (SyncE) and hybrid clocking	SyncE is a physical layer technology that uses Synchronization Status Message (SSM) and Ethernet Synchronization Message Channel (ESMC) to achieve clock synchronization between upstream and downstream devices. When the hybrid clocking mode is enabled, SyncE is used to provide frequency synchronization, while PTP is used to provide Time of Day (ToD) and phase synchronization.
		Control-plane management ACL logging	Monitors the control-plane ACL flows and creates log messages about packets that match an access control list entry (ACE) applied on a management interface in inbound direction.
		Redistribute iBGP route to OSPF	New CLI to allow or disallow redistribution of the internal BGP (iBGP) routes to OSPF.
		View BGP routes based on community attributes	New show commands to display the BGP routes that match a specific community number, any community number from the community list, or any extended attribute from the extended community list.
		CLI enhancements	The show tech-support command now displays transceiver information. The transceiver and interface parameters are now optional for the show interface phy-eth command. Based on the BGP as-notation present in the configuration, the OSPFv2/v3 and BGP show configuration commands now display as-notation based output.
		ZTD automatic upgrade related changes	To upgrade OS10 automatically using the Zero-Touch Deployment (ZTD) feature, use DHCP Option 240.
