Description

 

 

 

 

CR00006503

IP Gateway

2

Large UDP packets sometimes caused a memory corruption, which could

 

 

 

cause unexpected switch behaviour, including reboots.

 

 

 

This issue has been resolved.

 

 

 

 

CR00012264

IP Gateway

2

Multicast packets were incorrectly being sent to the CPU when the switch

 

 

 

received them on an IP interface that did not have DVMRP or PIM enabled

 

 

 

on it. This could result in unexpectedly high CPU usage statistics.

 

 

 

This issue has been resolved.

 

 

 

 

CR00012417

Switch, Utility

2

The switch sometimes did not process ARP requests fast enough to

 

 

 

prevent VRRP from changing mastership in the network.

 

 

 

This issue has been resolved.

 

 

 

 

CR00012455

BOOTP,

2

When the switch’s BOOTP relay agent relayed a DHCP offer to a locally-

 

IP Gateway

 

attached DHCP client, the switch added an ARP entry with an incorrect

 

 

 

port number. This meant packets from clients were forwarded by the CPU

 

 

 

instead of being switched in hardware.

 

 

 

This issue has been resolved.

 

 

 

 

CR00012504

BOOTP

2

There was a synchronisation issue between the software IP ARP table and

 

 

 

the hardware IP table, when a switch was configured for BOOTP relay and

 

 

 

multihoming concurrently. This could cause packets destined for clients to

 

 

 

be forwarded by the CPU or dropped instead of being switched in

 

 

 

hardware.

 

 

 

This issue has been resolved.

 

 

 

 

CR00012725

IP Gateway,

2

If a destination could be reached by both an interface route and a backup

 

Switch

 

route (a static route with the same destination as the network address of

 

 

 

the interface), in some circumstances the switch did not add either route

 

 

 

to its hardware route table. This stopped the switch from sending traffic

 

 

 

via either the interface or the backup route.

 

 

 

This situation has been resolved. The switch now correctly uses the

 

 

 

interface route when the interface is up and the backup route when the

 

 

 

interface is down.

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.
