IMPORTANT: If TACACS+ is enabled, you must login using TACACS+ authentication when connecting via the console or Telnet/SSH/HTTP/HTTPS. Backdoor for console is always enabled, so you can connect using notacacs and the administrator password even if the backdoor (telnet) or secure backdoor (secbd) are disabled.

If Telnet backdoor is enabled (telnet ena), type in notacacs as a backdoor to bypass TACACS+ checking, and use the administrator password to log into the switch. The switch allows this even if TACACS+ servers are available.

If secure backdoor is enabled (secbd ena), type in notacacs as a backdoor to bypass TACACS+ checking, and use the administrator password to log into the switch. The switch allows this only if TACACS+ servers are not available.

NTP server configuration

These commands enable you to synchronize the switch clock to a Network Time Protocol (NTP) server. By default, this option is disabled.

The following table describes the NTP Server Configuration commands.

Table 60 NTP Server Configuration commands

Command

Description

[no] ntp prisrv <IP address>

Prompts for the IP addresses of the primary NTP server to which you

 

want to synchronize the switch clock. For example, 100.10.1.1

 

Command mode: Global configuration

[no] ntp secsrv <IP address>

Prompts for the IP addresses of the secondary NTP server to which

 

you want to synchronize the switch clock. For example, 100.10.1.2

 

Command mode: Global configuration

ntp interval <1-44640>

Specifies the interval, in minutes (1-44640), to resynchronize the

 

switch clock with the NTP server. The default is 1440 seconds.

 

Command mode: Global configuration

ntp timezone <hh:mm>

Configures the NTP time zone offset from Greenwich Mean Time

 

(GMT), in hours and minutes. The offset format is HH:MM.

 

Command mode: Global configuration

[no] ntp daylightsavings

Disables or enables daylight saving time in the system clock. When

 

enabled, the switch will add an extra hour to the system clock so that

 

it is consistent with the local clock. By default, this option is disabled.

 

Command mode: Global configuration

ntp enable

Enables the NTP synchronization service.

 

Command mode: Global configuration

no ntp enable

Disables the NTP synchronization service. This is the default.

 

Command mode: Global configuration

show ntp

Displays the current NTP service settings.

 

Command mode: All

NEC N8406-022 manual NTP server configuration

N8406-022 specifications

The NEC N8406-022 is a robust and versatile networking device designed primarily for organizations requiring high-performance connectivity solutions. As part of NEC's extensive portfolio of networking equipment, the N8406-022 is engineered to address the demands of modern enterprise environments, ensuring seamless communication and data processing capabilities.

One of the key features of the N8406-022 is its multi-layer switching functionality. This device supports Layer 2 and Layer 3 switching, allowing for efficient data routing and reducing latency within local area networks (LANs). This capability is particularly beneficial for businesses that rely on real-time data access and transfer, such as those in financial services, media, and telecommunications.

The N8406-022 is equipped with advanced Quality of Service (QoS) features that help prioritize critical network traffic. This means that voice and video data packets can be given precedence over less time-sensitive information, ensuring that essential communication remains clear and uninterrupted. This is crucial for organizations leveraging VoIP and video conferencing solutions.

In terms of connectivity, the NEC N8406-022 offers a variety of ports, including multiple Gigabit Ethernet ports, which facilitate high-speed data transfer and enable seamless integration into existing network infrastructures. The device may also include 10 Gigabit SFP+ ports, providing the flexibility for high-capacity uplinks to support bandwidth-intensive applications and storage solutions.

Security is another focal point of the NEC N8406-022, with integrated features such as VLAN support, access control lists (ACLs), and port security measures. These capabilities protect sensitive data from unauthorized access and ensure that only legitimate users and devices can connect to the network.

Moreover, the N8406-022 often incorporates advanced energy-efficient technologies that minimize power consumption without compromising performance. This not only contributes to operational cost savings but also supports organizations in their sustainability efforts.

With its combination of performance, security, and energy efficiency, the NEC N8406-022 stands out as a reliable networking solution suitable for a wide range of enterprises looking to enhance their connectivity and operational efficiency. Whether deployed in data centers or as part of a corporate network, this device is built to meet the evolving demands of today’s digital landscape.
