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

47

PCR: 03511

Module: IPG

Level: 3

The special group entry 01-00-5e-00-00-02 was being written to the layer 2 forwarding database to identify router ports for IGMP snooping. Router ports are now identified from software, so this special group entry is no longer written to the layer 2 forwarding database.

PCR: 03514

Module: IPSEC

Level: 2

An incorrect IPSec Security Association (SA) was used to transmit packets when the SA’s IP address was assigned dynamically on another VPN gateway. This issue has been resolved.

PCR: 03515 Module: DHCP

Level: 3

DHCP was offering network and broadcast addresses to clients. This issue has been resolved.

PCR: 03516

Module: SWI

Level: 3

Continuous messages associated with CAM are sometimes generated on SwitchBlade series switches. If this happens, please contact your authorised distributor or reseller so that this issue can be resolved. The messages are similar to the following:

swiCXeVirtCamTranslateAddress - ulEntryNo:4294967254 entries:8192 last:106495.

PCR: 03517

Module: FIREWALL

Level: 3

An error was not returned if the SET FIREWALL POLICY RULE command was executed with PROTOCOL=1 when ICMP forwarding was turned on. This issue has been resolved so that an error is now displayed.

PCR: 03522

Module: IKMP

Level: 3

ISAKMP suffered an error when it encountered unknown cryptographic algorithms. This issue has been resolved.

PCR: 03523

Module: FIREWALL

Level: 2

In some circumstances the checksum for the TCP header was set to zero.

This issue has been resolved.

PCR: 03526

Module: SWI

Level: 3

The Switch MIB did not show the correct dot1StpPriority value. This issue has been resolved.

PCR: 03527

Module: BGP

Level: 4

Session-only counters have been added to the MIB entry for BGP peers.

PCR: 03532

Module: FIREWALL

Level: 2

Occasionally the TCP connection was terminated early during an IDENT proxy TCP session. 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.
