Patch Release Note

addresses in that range that were not allocated at that time, resulting in duplicate addresses appearing on the free list for allocation. This has been resolved by allowing DHCP to reclaim only those addresses that are currently in use by one of its clients.

PCR: 03709 Module: SWCX

Level: 3

The PM table portmap was being updated each time a port was unplugged or a link went down.

PCR: 03712

Module: SW

Level: 3

The port security feature of limiting the number of MAC addresses learned on a port, was including static address entries even with the ADD SWITCH FILTER command LEARN parameter set to default. This issue has been resolved.

PCR: 03716

Module: STP

Level: 3

When AT-9800 Series switches, were operated in rapid STP mode, the point to point field was not updating when speed or duplex changes occurred to a port. This issue has been resolved.

PCR: 03720

Module: STP

Level: 1

When changing from RSTP to STP mode, the STP command RSTPTYPE parameter was still appearing in the SHOW DYNAMIC command output. This issue has been resolved so that the RSTPTYPE parameter is no longer displayed in the command output.

Also when changing between RSTP and STP modes, disabled STP ports were not remaining in the disabled state. This issue has also been resolved.

PCR: 03720

Module: STP

Level: 2

When changing from RSTP to STP mode, the STPCOMPATIBLE option for the RSTPTYPE parameter incorrectly appeared in the dynamic configuration. Also, when changing from RSTP to STP mode or vice versa, disabled STP ports did not remain in the disabled state. These issues have been resolved.

PCR: 03723

Module: BGP

Level: 2

BGP routes that were added after a summary aggregate route had been formed were not suppressed. This issue has been resolved: all routes added after summary aggregate route creation are also now suppressed.

The SHOW BGP ROUTE command displayed unselected routes as the "best" route, until they had been processed. This issue has been resolved.

When a single route was deleted from an aggregate route, the aggregate route was deleted, even if it contained other routes. This issue has been resolved.

PCR: 03725 Module: SWCX

Level: 3

The maximum Layer 3 throughput across line cards was only 25% under some circumstances. This issue has been resolved.

PCR: 03728

Module: IPG

Level: 4

A field has been added to the SHOW IP command output that displays whether the IP ARP log is enabled or disabled.

SB251-13 specifications

The Allied Telesis SB251-13 is a robust Layer 2 managed switch designed to meet the demands of various networking environments. With a comprehensive set of features, it serves as an ideal solution for enterprises looking to enhance their network infrastructure while maintaining performance and reliability.

One of the standout features of the SB251-13 is its 24 Gigabit Ethernet ports, which provide high-speed connectivity essential for modern applications. This switch supports both copper and fiber connections, making it versatile for different deployment scenarios. Additionally, it includes two SFP (Small Form-Factor Pluggable) ports that enable flexibility in uplink configurations, allowing for connectivity over longer distances with fiber optics.

The switch operates on a Layer 2 architecture, which ensures efficient data handling and robust traffic management. With VLAN (Virtual Local Area Network) support, users can segment their networks for improved traffic isolation and security. This feature is particularly beneficial in environments where segmentation is critical for performance and compliance.

Quality of Service (QoS) is another critical characteristic of the SB251-13, enabling priority-based traffic handling. This means that time-sensitive data, such as VoIP or video streams, can be given precedence over less critical traffic. This prioritization enhances the overall user experience and is vital for ensuring the smooth operation of real-time applications.

Allied Telesis also includes advanced security features in the SB251-13, such as port security, MAC address filtering, and access control lists (ACLs). These measures help protect the network from unauthorized access and potential threats, making it suitable for both enterprise and educational environments.

Power over Ethernet (PoE) support is another significant advantage of the SB251-13. This feature allows the switch to provide power to connected devices like IP cameras, phones, and access points, eliminating the need for separate power sources and making installations cleaner and more efficient.

The SB251-13 is also equipped with a user-friendly web-based management interface, facilitating easy configuration and monitoring. Network administrators can quickly set up, manage, and troubleshoot, streamlining operations and reducing downtime.

In conclusion, the Allied Telesis SB251-13 stands out as a sophisticated managed switch that combines performance, security, and manageability. Its rich feature set makes it a valuable asset for organizations aiming to build a reliable and efficient network infrastructure.
