Extended Monitoring of CPU Utilisation (CR00012616)

This Software Version includes a new feature for monitoring CPU utilisation. You can now set the switch to capture data about which specific functions the CPU is executing, and what level of instantaneous usage the CPU is experiencing. This allows you, in conjunction with your authorised distributor or reseller, to diagnose the causes of high rates of CPU utilisation on the switch.

You can set the switch to capture data continuously, or only when the CPU experiences a specific level of instantaneous usage. The switch holds up to 500 entries (10 seconds) of data about CPU utilisation.

To capture data when the CPU is experiencing a specific amount of instantaneous usage, set the start and start percentages with the command:

activate cpu extended start=1..100 [stop=1..100]

When a start percentage is set, the switch automatically disables extended monitoring once it has 500 data entries.

To enable extended monitoring, use the command:

enable cpu extended

This command also lets you capture data immediately, without first setting start and stop percentages. This adds data entries continuously, until you stop it. Only the last 10 seconds of data entries are stored.

To stop capturing data, and reset the start and stop parameters if they are set, use the command:

disable cpu extended

To remove data entries and reset the start and stop parameters in the activate cpu extended command, use the command:

reset cpu utilisation

This command interrupts active data capturing for a specific event. However, monitoring remains enabled, and continues to collect data. This means you can capture data for a particular event without having to disable and re-enable this feature.

To see the extended CPU utilisation information (Figure 1, Table 1), use the new optional extended parameter in the command:

show cpu extended

4000 Series specifications

The Allied Telesis 4000 Series is designed to meet the growing demands for reliable and scalable networking solutions in enterprise environments. This series offers a range of stackable, Layer 2 and Layer 3 Ethernet switches, combining advanced features with robust performance to ensure seamless connectivity and superior network management.

One of the standout features of the Allied Telesis 4000 Series is its versatile stacking capability. The switches can be stacked together, enabling them to function as a single unit. This simplifies network management and provides enhanced redundancy, allowing for easy scaling without disrupting operations. The stacking technology supports high-speed interconnections, ensuring that data transfer between switches remains efficient and reliable.

The 4000 Series is equipped with advanced Layer 2 and Layer 3 switching functionalities. This dual-layer capability allows for both basic data linking and more complex routing operations, providing a flexible solution for organizations with diverse networking needs. With support for VLAN segmentation, organizations can optimize their bandwidth usage and enhance security by isolating network traffic.

Security is a crucial aspect of the Allied Telesis 4000 Series. Features such as IEEE 802.1X port-based access control, dynamic VLAN assignment, and advanced access control lists (ACLs) ensure that unauthorized access is prevented. The switches also support secure management protocols, providing peace of mind for network administrators who need to maintain compliance with industry regulations.

The Allied Telesis 4000 Series integrates Power over Ethernet (PoE) technology, enabling the switches to supply power to connected devices, such as IP cameras and VoIP phones, directly through the Ethernet cable. This eliminates the need for separate power supplies, simplifying installation and reducing clutter, particularly in environments where space is at a premium.

For performance, the 4000 Series boasts high throughput and low latency, making it suitable for bandwidth-intensive applications. The switches come equipped with advanced Quality of Service (QoS) features, allowing network administrators to prioritize critical traffic and ensure that applications perform optimally, even during peak usage times.

In conclusion, the Allied Telesis 4000 Series offers a comprehensive solution for organizations seeking reliable, secure, and scalable networking equipment. With its advanced stacking capabilities, dual-layer functionality, robust security features, and PoE support, this series is well-suited for modern enterprise networking demands. Whether for a small office or a larger data center, the Allied Telesis 4000 Series delivers the performance and flexibility required in today’s dynamic networking environments.
