Patch SB251-13 For SwitchBlade 4000 Series Switches and AT-9800 Series Switches

13

PCR: 031003 Module: QOS

Level: 3

The SET QOS VLANREMAP command was incorrectly saving configuration files. This was resulting in errors occurring when the file was executed. This issue has been resolved so that the file is saved in the correct form.

PCR: 031005 Module: SWCX

Level: 3

CAM errors were appearing when the ENABLE SWITCH BIST command was run multiple times. This issue has been resolved.

PCR: 031006 Module: STP SWI

Level: 2

When line cards were hotswapped, the card’s STPs were not being correctly reset to indicate that the card had been exchanged. This sometimes resulted in a failure to select the preferred link, during the link re-establishment phase. This issue has been resolved.

PCR: 031007 Module: CFLASH

Level: 2

On the AT-9800, files with no extension were causing fatal errors when stored on compact flash cards. This issue has been resolved to ensure that these files are handled correctly.

PCR: 031008 Module: CFLASH INSTALL

Level: 2

On the AT-9800, the configuration file could be set from compact flash files held in directories other than the root. This issue has been resolved by preventing the configuration being set from files other than those located in the root directory.

PCR: 031012 Module: PIM

Level: 2

The prune time limit was not being cancelled when an IGMP join was received by the switch. This was forcing the switch to send a Graft message in the upstream direction. This issue has been resolved by cancelling the prune time limit whenever an IGMP join is received.

PCR: 031014 Module: SWCX

Level: 2

When the SWITCH PORT command parameters, 10HMAUTO, 10MFAUTO, 100MHAUTO etc, were used to set a port to auto negotiate at a particular speed, the port speed would not be retained following a card hot swap. This issue has been resolved.

PCR: 031015 Module: STP

Level: 2

The PORT and PORTPRIORITY parameters of the STP PORT command were not always updating switch instances on ports that are members of multiple STP instances. This issue has been resolved.

PCR: 031020 Module: PIM

Level: 2

When the switch received a generation ID change message, it was not responding by sending a PIM HELLO message. This issue has been resolved.

PCR: 031030 Module: SWCX

Level: 3

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.
