Technical Specifications

Main Features and Advantages

• Advanced Switching and Routing Capabilities: The Extreme X670-G2-48x-4q supports sophisticated and intelligent Layer 2 switching as well as Layer 3 IPv4/IPv6 routing. It features policy-based switching/routing, Provider Bridges, bidirectional ingress and egress Access Control Lists (ACLs), and bandwidth control with 8 Kbps granularity for both ingress and egress. It also supports MPLS LSP-based Layer 3 forwarding and Hierarchical VPLS (H-VPLS) for transparent LAN services, enabling scalable network architectures primarily used for Carrier Ethernet network deployment.
• High Reliability and Availability: The X670-G2 series supports Ethernet Automatic Protection Switching (EAPS), which provides IP networks with resilience and uptime comparable to traditional voice networks. EAPS achieves sub-second recovery, offering consistent failover regardless of the number of VLANs, network nodes, or topology in Extreme Networks-recommended configurations. It also supports Spanning Tree (802.1D), Per VLAN Spanning Tree (PVST+), Rapid Spanning Tree (802.1w), and Multiple Instances of Spanning Tree (802.1s) protocols for Layer 2 resilience. Furthermore, it employs software-enhanced availability, continuously monitoring unlink connections using advanced Layer 3 protocols such as OSPF, VRRP, and Extreme Standby Router Protocol (ESRP, supported in Layer 2 or Layer 3), and dynamically rerouting traffic around issues. It also supports Equal Cost Multipath (ECMP) routing, allowing uplinks to be load-balanced for performance and cost savings while supporting redundant failover. If an unlink fails, traffic is automatically routed to remaining uplinks, maintaining connectivity. Link Aggregation (802.3AD) enables trunking of up to 32 links on a single logical connection, providing up to 320 Gbps of redundant bandwidth per logical connection. Multi-Switch LAG (MLAG) addresses bandwidth limitations and enhances network resilience by routing traffic around bottlenecks, reducing single points of failure risks, and enabling load balancing across multiple switches. Hardware redundancy is supported with dual redundant AC/DC power supplies and standardized N+1 redundant hot-swappable fan units.
• Rich Networking Technologies: The Extreme X670-G2-48x-4q supports multiple networking technologies, including 40 Gigabit Ethernet (40GBase-X) and 10 Gigabit Ethernet (10GBase-X) over optical fiber media. It provides low-latency cut-through switching and is compatible with the ExtremeXOS modular operating system, enabling comprehensive network management and control. It also supports Boundary Clock (BC), Transparent Clock (TC), and Ordinary Clock (OC) for synchronizing phase and frequency, allowing the network and connected devices to achieve microsecond-level accuracy over Ethernet connections. Additionally, it supports Port Mirroring, allowing many-to-one and one-to-many port mirroring. Traffic can be mirrored to external network appliances such as intrusion detection devices for trend analysis or used by network administrators for diagnostic purposes. Port mirroring can also be enabled across switches in a stack. The X670-G2 series supports up to 4,096 ingress ACLs and 1,024 egress ACLs per system based on Layer 2-, 3-, or 4-header information such as MAC or IP source/destination addresses. ACLs are used for traffic filtering and classification to control bandwidth, priority, mirroring, and policy-based routing/switching. The switch effectively handles Denial of Service (DoS) attacks. If it detects an unusually large number of packets in the CPU input queue, it automatically generates ACLs to block these packets from reaching the CPU. These ACLs are removed after a period and reinstated if the attack persists. ASIC-based LPM routing eliminates the need for control plane software to learn new flows, enhancing network resilience against DoS attacks. It supports comprehensive network management via Command Line Interface (CLI), SNMP v1, v2c, v3, and ExtremeXOS ScreenPlay embedded XML-based Web user interface. With a variety of management options and consistency across other Extreme Networks modular and stackable switches, the X670-G2 series simplifies management for demanding converged applications.
• Flexible Configuration and Stacking Capabilities: The Extreme X670-G2-48x-4q offers flexible port configurations. Each QSFP+ port can be independently set to operate as a single 40 Gigabit Ethernet port or split into 4 x 10 Gigabit Ethernet ports. This allows for up to 64 10Gb ports when all QSFP+ ports are split or a mix of 40Gb and 10Gb connections based on network requirements. The X670-G2 series supports four stacking methods: SummitStack-V, SummitStack-V80, SummitStack-V160, and SummitStack-V320. SummitStack-V enables flexible stacking over 10 Gigabit Ethernet. The Summit X670-G2-48x-4q can be stacked with other switches in the series to form a larger logical switch, enhancing network scalability and flexibility.
