CR00011585

OSPF

2

Adding the same OSPF stub or host twice caused OSPF to suspend its

 

 

 

operation, causing neighbour relationships to eventually fail.

 

 

 

This issue has been resolved.

 

 

 

 

CR00012067

OSPF

2

A summary LSA was not turned into a route if the destination and mask

 

 

 

fell inside one of the switch’s active ranges, unless it exactly matched the

 

 

 

active range’s address and mask.

 

 

 

This complied with RFC 1583 section 16.2. However, the recommended

 

 

 

behaviour has been modified in RFC 2328 section 16.2. To comply with

 

 

 

this, the LSA is now calculated if it falls inside one of the switch’s active

 

 

 

ranges.

 

 

 

 

CR00012606

STP

2

Processing of an invalid STP packet could result in an STP timeout value

 

 

 

being incorrectly set to 0.

 

 

 

This issue has been resolved, so the timeout can never be set to 0.

 

 

 

 

CR00012783

VLAN

2

When the mirror port was specified on the switch, untagged ports would

 

 

 

start to transmit tagged traffic.

 

 

 

This issue has been resolved.

 

 

 

 

CR00013178

Switch

2

In packet storm conditions, involving a high percentage of routing

 

 

 

protocol packets, the switch could become very low on resources, and

 

 

 

reboot.

 

 

 

This issue has been resolved.

 

 

 

 

CR00013275

Firewall

2

If a firewall policy had a list attached to it (by using the command add

 

 

 

firewall policy=policy-namelist=list-name), destroying the policy

 

 

 

would cause the switch to reboot.

 

 

 

This issue has been resolved.

 

 

 

 

CR00013380

IP Gateway

2

In certain unusual network configurations, the switch would respond to

 

 

 

ICMP messages addressed to it with the wrong source IP address in the

 

 

 

reply.

 

 

 

This issue has been resolved.

 

 

 

 

CR00013598

IP Gateway

2

If the switch had multiple default routes with the same nexthop (such as

 

 

 

one static default route and a default route learnt by RIP) and one of those

 

 

 

default routes was withdrawn, then the hardware entry for the default

 

 

 

route would be removed. This meant that traffic destined to that route

 

 

 

was forwarded to the CPU, which could result in a performance

 

 

 

degradation.

 

 

 

This issue has been resolved.

 

 

 

 

CR00014044

IGMP

2

When large numbers of multicast streams were passing through the

 

 

 

switch and there was no multicast routing protocol running (such as PIM

 

 

 

or DVMRP), the CPU would experience regular periods of extended high

 

 

 

utilisation. This could result in lost control packets and network instability.

 

 

 

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.
