Explains SNTP operating modes: Broadcast, DHCP, and Unicast, for time synchronization.
Details NTP's role in synchronizing time across distributed servers and clients for event correlation.
Outlines the procedure to select and enable a time synchronization protocol like TimeP, SNTP, or NTP.
Enables validation of SNTP messages from servers before updating network time, enhancing security.
Command to configure key-id, authentication mode (MD5), and key-value for SNTP authentication.
Steps to configure unicast or broadcast mode for SNTP authentication and change between modes.
How the switch requests time updates from multiple SNTP servers when unicast time polling is enabled.
Explains NTP, its use of UDP, strata, and security features like encrypted authentication.
Command used for authentication of NTP server by the NTP client.
Command used to configure NTP servers, including IP address, key, and polling intervals.
Guides on viewing port status and configuring parameters like speed, duplex, and flow control.
Monitors link state between switches, blocking ports if link fails to ensure bidirectional traffic.
Overview of considerations for planning a PoE application, including port assignments, security, and power requirements.
Details how power allocation is prioritized when PD demand exceeds available power.
CLI commands for enabling/disabling PoE, setting priority, and configuring thresholds.
How LLDP information can be used for automatic power configuration based on PD capabilities.
Covers methods for configuring trunks, including Dynamic LACP and Static trunks.
Details how the switch automatically negotiates trunked links using LACP active or passive modes.
How the switch automatically or manually configures dynamic or static LACP trunk groups.
Controls traffic rate on a per-port basis for inbound or outbound traffic, dropping excess traffic.
