10Patch Release Note

PCR: 02081

Module: FILE, FFS

Network affecting: No

If the FILE module was required to re-write a file, the existing file would be deleted before the size of the new file was known. This issue has been resolved.

PCR: 02082

Module: OSPF

Network affecting: Yes

OSPF virtual links running across a single network segment would accept

0.0.0.0as the next hop address. This was inherited by derivative routes, making them unusable. This issue has been resolved.

PCR: 02086

Module: FFS

Network affecting: No

If a file ended short of an erase block boundary and a compaction was started, the block in which the file was stored was not erased, causing errors when new files were written. Also, if the last file in the filing system ended on or short of an erase block boundary, and a compaction was started, then compaction would fail. These issues have been resolved.

PCR: 02088

Module: SWI

Network affecting: No

Port mirroring on the Rapier 48 and 48i was not operating correctly because

Destination Lookup Failure (DLF) frames were sent from the mirror port.

This issue has been resolved.

PCR: 02095

Module: SWI

Network affecting: No

The software routing performance of the Rapier 48 and Rapier 48i has been enhanced.

PCR: 02101

Module: SWI

Network affecting: No

The layer 3 hardware table was not sorted properly when it contained a very wide range of IP addresses (eg. 10.0.0.1 - 205.33.3.1). This caused a small number of packets to be routed by software rather than hardware. This issue has been resolved.

PCR: 02104

Module: TRG

Network affecting: No

The periodic and time trigger counts were incrementing by two instead of one on each update. This issue has been resolved.

PCR: 02105

Module: FFS

Network affecting: No

An error occurred when the FLASH write driver was required to write values that were not long-word aligned and were at the driver’s page boundary. The driver attempted to write into the next section of memory. It also attempted to read the status of this section of memory, and misinterpreted the result as a low Vpp voltage. Also, errors occurred during FLASH compaction. These issues have been resolved.

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.
