IP Gateway,

2

Previously, if a VLAN had been configured for use as the primary interface

 

VLAN, VRRP

 

for a VRID within VRRP, it was possible to delete the VLAN’s IP interface.

 

 

 

Also, if the IP address of the VLAN was changed (by using the command

 

 

 

set ip), the priority of the VRID was not recalculated.

 

 

 

These issues have been resolved, resulting in the following VRRP

 

 

 

behaviour:

 

 

 

An IP interface cannot be deleted if it is one of the primary interfaces

 

 

 

already configured for VRRP

 

 

 

An IP interface can still be deleted if it is a monitored interface, because

 

 

 

VRRP is only monitoring the state of the interface and does not need

 

 

 

the interface to have an IP address.

 

 

 

A VLAN cannot be destroyed if it is a monitored interface of VRRP.

 

 

 

The command set ip can be used to change the IP address of the

 

 

 

interface even if VRRP is active. VRRP will recalculate the priority of the

 

 

 

specific VRIDs using this interface. However, the IP address of the VRID

 

 

 

cannot be changed.

 

 

 

 

CR00012782

Switch, VLAN,

2

If a VRRP interface (including the virtual VRRP MAC address) is elected as

 

VRRP

 

the VRRP master for a VLAN, and that VLAN has no ports on a given

 

 

 

switch instance, the VRRP interface is not added to that switch instance.

 

 

 

This is correct behaviour. However, if a user later added ports to the VLAN

 

 

 

on that switch instance, the VRRP interface was still not added. This meant

 

 

 

the switch did not respond to ARP traffic destined for the VRRP MAC

 

 

 

address if the traffic came via that switch instance. Also, the VRRP

 

 

 

interface was not always correctly deleted from switch instances.

 

 

 

These issues have been resolved.

 

 

 

 

CR00012961

Switch

2

In very rare circumstances, the switch rebooted when it attempted to

 

 

 

update the downstream port members of a layer 3 multicast stream.

 

 

 

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.
