(Optional) Configuring Access Control for SMPTE-2059-2 Clock Sources
This section describes how to configure access control for SNMPTE-2059-2 clock sources. On a large SMPTE-2059-2 clock synchronization network, lots of devices may participate in dynamic clock source selection. In this case, a malicious clock attack or configuration error may cause clock flapping on the entire network. You can enable the control access for SMPTE-2059-2 clock sources so that the system selects a clock source within a specified range.
Procedure
- Run system-view
The system view is displayed.
- Run ptp acl enable
The access control function is enabled for SMPTE-2059-2 clock sources.
- Run ptp acl-permit-clockid clockid-value
A clock ID is configured for an SMPTE-2059-2 device that is not allowed to participate in local BMC selection.
- Run commit
The configuration is committed.
