Protocol (STP), Rapid Spanning Tree (RSTP), per VLAN STP (PVST), per VLAN group STP (PVGST), and Multi-instance Spanning Tree (MSTP). The switches can also support Brocade Metro Ring Protocol (MRP) for sub-second service restoration in ring topologies, Virtual Switch Redundancy Protocol (VSRP) for redundant switch configurations, VLAN topology grouping, and VLAN tunneling for advanced Layer 2 service configurations.

The IBM Ethernet r-series switches are designed to support Layer 3 feature set for scalable Exterior Gateway and Interior Gateway Protocols (EGP and IGP). The switches can support a wide array of IPv4 routing protocols including RIPv1/v2, OSPFv2, BGP-4, and IS-IS. To future-proof the network, support for IPv6 routing protocols include RIPng, OSPFv3, and BGP-4+.

A scalable, resilient network can be built using IEEE 802.3ad Link Aggregation for up to eight links. BPDU Guard and Root Guard support prevent rogue hijacking of the spanning tree root and maintain a contention-free and loop-free environment, especially during dynamic network deployments. Additionally, IP SouceGuard can be configured to prevent IP source address spoofing.

With Brocade Direct Routing (BDR), the Forwarding Information Base (FIB) is downloaded to the hardware-based forwarding engine on each line module. Policy Based Routing (PBR) allows customizable routing policies using ACLs. This feature can be used to balance network usage by controlling the network paths for different traffic flows.

Virtual Router Redundancy Protocol (VRRP) and VRRPE enable the switches to operate as a backup router to other network routers. In the event of a router failure, the switch can automatically and seamlessly perform the task of the failed router.

The IBM Ethernet r-series switches can help to meet the growing use of streaming video and voice in a converged network by providing hardware-based support for a number of multicast protocols including MSDP, PIM-SM, and PIM-DM. This allows network managers to efficiently deploy next generation multicast applications.

Network administrators can enforce QoS policies based on port, VLAN, source MAC, ACL rules, IEEE 802.1p priority, Type of Service (ToS), DiffServe settings, or Rate Limiting status. The wide variety of methods supported can help administrators to granularly tune traffic according to their needs, such as strict priority for Voice over IP, video, and high-performance computing applications.

Combinations of Strict Priority (SP) and Weighted Fair Queuing (WFQ) can provide flexibility for network administrators. In the event of egress port congestion, traffic policies can be configured for tail drop or weighted random early detection (WRED) operation.

Advanced bandwidth management can allow intelligent bandwidth management using hardware based enforcement of Committed Information Rate (CIR) with Excess Burst control capabilities and seamless integration with other QoS features.

Wire-speed Access Control Lists (ACL) is designed to control packet forwarding and restrict access to the system management interface, while providing wire- speed switching and routing. An extensible ACL implementation for Layer 3 and Layer 4 information identifies traffic based on source or destination IP address, IP protocol type, TCP or UDP port, IP precedence, or ToS values. Flexible Layer 2 implementation identifies traffic based on source or destination MAC address, Ethernet type, VLAN-ID values, and 802.1p values.

High priority voice and data traffic flow through the chassis utilizing the high performance hardware-based QoS features of the switches. Wire-speed security can be maintained by locking out unauthorized users with port security, by filtering DoS and unauthorized traffic with ACLs, and by monitoring traffic flows with sFlow. The switches can allow you to grow from just 24 ports of 10/100/ 1000 at the edge and up to 1,536 ports of 10/100/ 1000 or 512 ports of 10-Gigabit Ethernet in the core. A common architecture across the entire series can meet the demands of enterprise network needs while incorporating resiliency, security, and scalability in
