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

43

When static DHCP was set to the first IP address in a range, that range would stay in the Reclaim mode. This issue has been resolved.

PCR: 03426

Module: IPV6

Level: 3

If the valid and preferred lifetimes of an IPv6 address for a given interface were set to infinity, they were not included in the dynamic configuration. This issue has been resolved.

PCR: 03428

Module: STP

Level: 3

In Rapid STP mode, ports did not always make rapid changes to the

Forwarding State when their roles changed from Alternate to either

Designated or Root. This issue has been resolved.

PCR: 03429 Module: SWI, VLAN

Level: 3

The SHOW VLAN command displayed a nonexistent port. This issue has been resolved.

PCR: 03430

Module: BGP

Level: 3

The BGP traps sent to either establish or lower its peer states were

 

incorrectly set. This issue has been resolved.

 

PCR: 03432

Module: STP

Level: 3

STP settings were not retained when a port was deleted from the VLAN that the STP belongs to. This issue has been resolved.

PCR: 03433

Module: CFLASH

Level: 2

A fatal error would occur if the command SET CFLASH DIRECTORY was used to set a non existent, or invalid directory. This issue has been resolved.

PCR: 03436 Module: IP, DHCP

Level: 3

When the device was acting as a DHCP client and the DHCP server provided a gateway address, a statically configured default route was deleted and replaced with a default route with the provided gateway address. The correct behaviour is to only delete a dynamic default route in this situation. This issue has been resolved; the correct behaviour is now applied.

PCR: 03438 Module: DHCP

Level: 3

A warning message will now appear if the DESTROY DHCP POLICY command is executed for a DHCP policy that has been used by one or more policies as the source of their configuration information. A parent policy can be destroyed with no affect on its child policies.

The new message is:

The destroyed policy <policy-name> has been used by another policy as a source of configuration information.

PCR: 03439

Module: IPX

Level: 3

The IPX traffic filter match counter was not incremented if a route was cached. This issue has been resolved.

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.
