Features in sb275a01

Software maintenance release sb275a01.rez includes the resolved issues and enhancements in the following tables.

Level 1

CR

Module

Level

Description

 

 

 

 

CR00004954

Switch

1

Previously, if the switch relearned a MAC address on a new switch

 

 

 

instance from a VLAN-tagged frame, it forwarded all frames for that MAC

 

 

 

address as tagged frames. This happened even if the destination port was

 

 

 

untagged.

 

 

 

This issue has been resolved.

 

 

 

 

CR00010870

LACP

1

Previously, if LACP was enabled, resetting a line card could cause the

 

 

 

switch to reboot.

 

 

 

This issue has been resolved.

 

 

 

 

CR00011417

SYSR

1

The switch occasionally lost communication with the slave switch

 

 

 

controller, for example, if the master controller took more than 30 seconds

 

 

 

to reboot.

 

 

 

This issue has been resolved.

 

 

 

 

CR00011601

HealthCheck

1

When the switch was receiving traffic at a high rate and processing it in

 

 

 

the CPU (for example, during a broadcast storm) hot-swapping, resetting

 

 

 

blades and health checks sometimes failed.

 

 

 

This issue has been resolved.

 

 

 

 

Level 2

CR

Module

Level

Description

 

 

 

 

CR00005408

IGMP

2

Sometimes a delay of up to 40 seconds occurred before the switch sent

 

 

 

unknown IGMP packets to the CPU for processing.

 

 

 

This issue has been resolved.

 

 

 

 

CR00008791

PIM4

2

Previously, L2 switching of multicast traffic did not always operate

 

 

 

correctly when L2 and L3 multicast were being used at the same time.

 

 

 

This issue has been resolved.

 

 

 

 

CR00009693

GUI Agent

2

Previously, using the GUI to view the ARP cache could cause the switch to

 

 

 

reboot if the ARP cache contained many thousands of records.

 

 

 

This issue has been resolved.

 

 

 

 

CR00010029

SYSR

2

If a slave switch controller initialised with an older SYSR version than the

 

 

 

master switch controller, and the slave switch controller contained an

 

 

 

invalid release licence, the master controller would reboot.

 

 

 

This issue has been resolved.

Allied Telesis 4000 Series manual Features in sb275a01, PIM4

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.
