Patch Release Note

PCR: 02260

Module: TTY

Network affecting: No

When a ‘\n’(LF) character was received, the router/switch did not recognise this as the termination of a command over Telnet. This issue has been resolved.

PCR: 02262

Module: DNS

Network affecting: No

Responses to MX record requests were not handled correctly if the preferred name in the MX record differed from the one that was requested. This issue has been resolved.

PCR: 02263

Module: VRRP

Network affecting: No

The virtual MAC address was used as the source MAC for all packets forwarded on an interface associated with a Virtual Router (VR). This was confusing when multiple VRs were defined over the same interface because only one virtual MAC address was ever used. The other virtual MAC addresses (for the other VR's) were only used if the source IP address matched the VR’s IP address. To avoid this confusion, the system MAC address is now always used unless the source IP address of the packet is the same as the VR’s IP address.

PCR: 02264

Module: PIM, DVMRP, SWI

Network affecting: No

PIM or DVMRP failed to see any data if IGMP snooping was on and DVMRP or PIM was enabled after the data stream had reached the router/ switch. This issue has been resolved.

PCR: 02265

Module: FIREWALL

Network affecting: No

MAC address lists were not working with Firewall rules. This issue has been resolved.

PCR: 02268

Module: FIREWALL

Network affecting: No

HTTP requests from a fixed IP address were erroneously reported as a host scan attack in the Firewall deny queue. This issue has been resolved.

PCR: 02269

Module: DUART, TM

Network affecting: No

Under certain circumstances, the Asyn Loopback Test failed. This issue has been resolved.

PCR: 02274

Module: TPAD

Network affecting: No

ARL message interrupts have been re-enabled after a software table rebuild to fix synchronisation of the software forwarding database with the hardware table.

PCR: 02275

Module: OSPF

Network affecting: No

Some routes were not added into the OSPF route list, and therefore were not added into the IP route table. This issue has been resolved.

PCR: 02276

Module: FIREWALL

Network affecting: No

The CREATE CONFIG command did not save the SOURCEPORT parameter to the configuration file when the low value of the source port range was set to zero. This issue has been resolved.

86222-21 specifications

Allied Telesis 86222-21 is a versatile and robust network switch designed for a variety of applications across different industries. This device is engineered to deliver high-performance connectivity, making it an ideal choice for both enterprise environments and smaller businesses looking to enhance their network infrastructure.

One of the standout features of the Allied Telesis 86222-21 is its support for advanced Layer 2 switching capabilities. This allows for efficient data transfer within local area networks (LANs) by enabling the management of data packets based on MAC addresses. The device is equipped with multiple Gigabit Ethernet ports, promoting fast and reliable connections for numerous devices and reducing latency in data transmission.

In a world increasingly dependent on cloud services and virtualization, the 86222-21 is designed to accommodate the growing need for bandwidth. It supports Power over Ethernet (PoE), which simplifies the installation of networked devices like IP cameras and wireless access points by providing power through the Ethernet cable, eliminating the need for separate power supplies. This not only streamlines device management but also enhances flexibility in network design.

Security is a paramount concern for any modern network, and this model addresses those needs with robust built-in security features. The device includes VLAN support, allowing for the segmentation of networks into distinct domains for enhanced data security and management. Access Control Lists (ACLs) further bolster network security by enabling fine-grained control over which devices can communicate with each other.

Allied Telesis 86222-21 also features an intuitive management interface, which is crucial for IT administrators responsible for maintaining network performance. The graphical user interface (GUI) and command line interface (CLI) provide flexibility in managing the switch, allowing for configuration changes and monitoring of network health with ease.

Additionally, this network switch is designed with energy efficiency in mind. It complies with various energy-saving standards, which not only reduces operational costs but also contributes to environmental sustainability.

Overall, the Allied Telesis 86222-21 is a powerful and flexible switch equipped with advanced features that cater to the needs of modern networks. It promotes efficient data management, robust security, and energy efficiency, making it a fitting solution for diverse networking requirements. Whether used in small offices or larger enterprise environments, its adaptability and performance capabilities make it a valuable asset in the pursuit of effective network communication.
