8Patch Release Note

PCR: 02098

Module: STP

Network affecting: No

STP always transmits untagged packets. If a port does not belong to a VLAN as an untagged port, then the port must belong to one VLAN as a tagged port. In this case, STP should transmit VLAN tagged packets out of the port.

PCR: 02123

Module: IPG

Network affecting: No

The IP, MASK, and ACTION parameters could not be set with the SET IP ROUTE FILTER command. This issue is resolved when the filter number is specified at the start of the command, for example:

SET IP ROUTE FILTER=filter-idIP=ipadd MASK=ipadd

ACTION={INCLUDEEXCLUDE}

where: filter-idis the filter number. Filter numbers are displayed in the output of the SHOW IP ROUTE FILTER command.

PCR 02138

Module: SWI

Network affecting: No

The built in Self Test Code for all Rapiers, except G6, has been improved to enhance the detection of faults in switch chip external packet memory.

PCR 02140

Module: OSPF

Network affecting: No

An AS boundary router advertises AS external LSAs to other routers. However, when the router’s configuration changed, either by adding an IP route filter, or by setting its ASEXTERNAL parameter to OFF using the SET OSPF ASEXTERNAL command followed by a restart, its neighbour state could not reach full state. Also, when the router had IP route filters configured, matched routes were not being flooded into other routers. However, these routes should still have been imported into the router’s own LSA database, but were not. These issues have been resolved.

PCR 02144

Module: IPG

Network affecting:No

The IPG module has been enhanced to support gratiutous ARP request and

ARP reply packets.

PCR 02151

Module: IPG

Network affecting: No

The Rapier was not detecting invalid checksums in ICMP echo request packets. This issue has been resolved. ICMP echo request packets with invalid checksums are now dropped and the ICMP inErrors and inDiscards counters are incremented.

PCR 02164

Module: DHCP

Network affecting: No

A simple DHCP range MIB and a trap have been added. The trap is triggered when a DHCP request cannot be satisfied. The gateway address and the interface address are sent as trap variables. The range table shows which range was exhausted. A debug variable, swiDebugBroadcomParityErrors has been added to the SWI module MIB to count the SDRAM parity errors in the packet memory of the Broadcom switch chip.

PCR 02176

Module: FIREWALL

Network affecting: No

Packets traversing in and out of the same public firewall interface were sometimes blocked. The firewall should only control packets passing between a public and a private interface. 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.
