23

PCR: 03224

Module: IPG

Level: 2

If an IP address was added using the AD IP INTERFACE IP=DHCP and the server could not assign an IP address due to a network problem affecting the server’s VLAN, any further frames transmitted to IP addresses on other VLANS would be blocked. This issue has been resolved.

PCR: 03227

Module: SWI

Level: 4

Previously, the default output of the SHOW SWITCH FDB command displayed the forwarding database information for ports on the controller card located in bay A. The default now displays all external ports for switch instances except for those on the controller card. This command no longer displays information about internal ports.

PCR: 03229 Module: LOAD

Level: 3

Zmodem was not naming some loaded files. This issue has been resolved.

PCR: 032231 STP

Level: 3

STP was advertising an incorrect length for BPDU packets. This issue has been resolved.

PCR: 03232

Module: BGP

Level: 3

Values for the KEEPALIVE and HOLDTIME parameters in the ADD BGP PEER and SET BGP PEER commands were not interacting correctly. This issue has been resolved.

PCR: 03234

Module: IPG

Level: 3

The PURGE IP command did not remove ENABLE IP IGMP from the configuration. This issue has been resolved.

PCR: 03236

Module: IPG

Level: 3

IGMP queries were being sent after IGMP was disabled. This issue has been resolved.

PCR: 03237

Module: IPG

Level: 2

RIP Request packets for IPv4 were not being transmitted when the link came up or when the switch restarted. This issue has been resolved.

PCR: 03238

Module: SWI

Level: 2

When RIP interfaces were deleted, the IP routes learned through those interfaces were not timing out correctly. Now, all IP routes learned though a RIP interface are removed when the RIP interface is deleted, and no timeouts occur.

PCR: 03239 Module: QOS

Level: 2

QoS Traffic Class maximum bandwidth limiting was being overwritten by the port or trunk maximum bandwidth value. This should only happen when the Traffic Class maximum bandwidth has not been set manually with

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.
