Patch 86253-03 For Rapier Series Switches

5

PCR: 03793

Module: RSVP

Level: 3

The ENABLE RSVP INTERFACE command did not succeed if IP was enabled after the RSVP interface had been created. Now, ENABLE RSVP INTERFACE will succeed regardless of when IP is enabled as long as an IP interface exists.

PCR: 03799 Module: DHCP

Level: 3

When a new static entry was allocated to a client, an old dynamic entry remained inuse for a full lease period. This issue has been resolved. The old entry will now be reclaimed when the client attempts to renew its lease and receives the new static entry.

IGMP Snooping All-Group Entry

Because IGMP is an IP-based protocol, multicast group membership for VLAN aware devices is on a per-VLAN basis. If at least one port in the VLAN is a member of a multicast group, multicast packets will be flooded onto all ports in the VLAN by default.

IGMP snooping enables the switch to forward multicast traffic intelligently on the switch. The switch listens to IGMP membership reports, queries and leaves messages to identify the switch ports that are members of multicast groups. Multicast traffic will only be forwarded to ports identified as members of the specific multicast group.

This enhancement allows network managers to prevent specified ports from acting as IGMP all-group ports, and specify which ports are allowed to behave as all-group entry ports, by using the ENABLE IP IGMP ALLGROUP command.

For example, consider a video streaming service which has 15 channels. When the switch receives IGMP membership reports destined for the address

239.0.0.2from an unauthorised user, all 15 channels of multicast data floods to that port, which may affect the service of the network. In order to avoid this, the network manager decides whether or not to allow a particular port to behave as an IGMP all-group port, e.g. port 8. Then, whenever the above IGMP membership report is sent, the switch will not automatically add port 8 as one of the egress ports for any IGMP membership report group, so video streaming will not get forwarded to disabled all-group ports selected by the network manager.

Commands

This enhancement modifies one command:

SHOW IP IGMP

and has two new commands:

ENABLE IP IGMP ALLGROUP

DISABLE IP IGMP ALLGROUP

Rapier Series specifications

The Allied Telesis Rapier Series represents a cutting-edge line of managed Ethernet switches designed for a variety of networking environments, including enterprise, campus, and industrial applications. Known for their advanced capabilities, reliability, and scalability, these switches are engineered to meet the ever-increasing demands for network performance and efficiency.

One of the standout features of the Rapier Series is its support for high-performance Layer 2 and Layer 3 switching. This dual capability allows for efficient management of network traffic, ensuring that data can flow without bottlenecks. With a robust architecture, the Rapier switches are capable of handling high-throughput applications, which makes them suitable for environments requiring constant connectivity and minimal downtime.

The Rapier Series incorporates advanced Quality of Service (QoS) mechanisms, enabling network administrators to prioritize traffic based on application needs. This is essential for applications such as VoIP and video conferencing, where latency and packet loss can significantly impact performance. By allowing precise control over traffic flows, the Rapier Series helps organizations maintain optimal user experiences even during peak usage.

Security is another critical focus of the Rapier Series. The switches come equipped with features such as IEEE 802.1X port-based authentication, which helps prevent unauthorized access to network resources. They also support VLANs (Virtual Local Area Networks), allowing for the segmentation of network traffic, which is crucial for both performance and security. Additionally, the switches offer features like Access Control Lists (ACLs) to provide further granular control over data access and flow.

The Rapier Series also emphasizes energy efficiency. With features such as Energy Efficient Ethernet (EEE), these switches minimize power consumption, aligning with global sustainability efforts and reducing operational costs. This attribute makes them an attractive choice for organizations looking to minimize their environmental footprint while keeping operational efficiency in mind.

In terms of management capabilities, the Rapier Series offers a range of options, including a user-friendly web-based interface, command-line interface (CLI), and SNMP (Simple Network Management Protocol) support. These facilitative management tools enable network administrators to monitor performance, configure settings, and troubleshoot issues in real time.

Overall, the Allied Telesis Rapier Series offers a comprehensive solution for modern networking challenges. With its blend of high performance, security features, energy efficiency, and user-friendly management options, the Rapier Series stands as a formidable choice for organizations aiming to build robust and reliable networks. Whether for small enterprises or large-scale deployments, the Rapier switches deliver the performance and flexibility needed to adapt to the dynamic demands of today’s networking landscape.
