Features in sb275a04

Software maintenance version sb275a04 includes all resolved issues and enhancements in earlier 2.7.5A versions, and the resolved issues and enhancements in the following tables.

Description

 

 

 

 

CR00007522

IP Gateway

2

The switch’s hardware IP route table occasionally did not contain the most

CR00012896

 

 

optimal route to a destination. This meant packets were sometimes sent

 

 

via sub-optimal routes. An additional effect was that when multiple equal-

 

 

 

cost routes existed a less than complete set of those routes would be

 

 

 

utilised.

 

 

 

This issue has been resolved, so that the switch forwards packets via the

 

 

 

best IP route(s) available.

 

 

 

 

CR00009026

IP Gateway,

2

The IP route cache (and therefore the Layer 3 IP routing table in hardware)

 

OSPF

 

was sometimes refreshed unnecessarily when OSPF SPF recalculation took

 

 

 

place as a result of OSPF receiving a router LSA update.

 

 

 

This issue has been resolved.

 

 

 

 

CR00009347

GUI

2

It was not possible to use the GUI to add untagged ports to the default

 

 

 

VLAN.

 

 

 

This issue has been resolved.

 

 

 

 

CR00009826

IP Gateway

2

When a static ARP is deleted, the switch sends out an ARP request to

 

 

 

attempt to create a dynamic ARP for that IP address. Previously, the switch

 

 

 

did not process the ARP response correctly and therefore did not add the

 

 

 

ARP to its ARP table.

 

 

 

This issue has been resolved. When a static ARP is deleted, the switch

 

 

 

attempts to create a dynamic ARP for that IP address, and will successfully

 

 

 

add it to the ARP table if a device responds.

 

 

 

 

CR00010170

OSPF

2

Route maps did not filter static routes of external type 2 when

 

 

 

redistributing them into OSPF.

 

 

 

This issue has been resolved.

 

 

 

 

CR00010598

OSPF

2

When filtering OSPF routes, IP route filters did not filter out intra-area

 

 

 

interface routes.

 

 

 

This issue has been resolved.

 

 

 

 

CR00010827

OSPF

2

Previously, OSPF would advertise LSU packets to the wrong area when a

 

 

 

stub area was altered.

 

 

 

This issue has been resolved.

 

 

 

 

CR00011219

IPv4

2

When the switch received an IP packet with invalid IP option length (a

 

 

 

corrupted packet), a reboot might occur.

 

 

 

This issue has been resolved.

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.
