Comprehensive virtualization capabilities

IRF2 (The second generation of Intelligent Resilient Framework)

S12500G-AF series switches support IRF2 technology, virtualizing up to 4 high-end devices into one logical device, which has powerful advantages in reliability, distribution and ease of management.

Reliability: Through patented hot backup technology, redundant backup of all information on the control plane and data plane and uninterrupted data forwarding are realized in the entire virtual architecture, which greatly enhances the reliability and high performance of the virtual architecture, and eliminates A single point of failure is avoided and business interruption is avoided.

Distribution: Through distributed cross-device link aggregation technology, load sharing and mutual backup of multiple uplinks are realized, thereby improving the redundancy of the entire network architecture and the utilization of link resources.

Ease of management: The entire elastic architecture shares one IP management, which simplifies network equipment management, simplifies network topology management, improves operational efficiency, and reduces maintenance costs.

MDC (Multitenant Devices Context）

S12500G-AF series switches can achieve 1:N virtualization capability through MDC technology, that is, one physical switch is virtualized into N logical switches, and up to 16 logical switches can be virtualized to meet the needs of multiple customers sharing core switches; The ports of a single board are divided into different MDCs, which can make full use of the capabilities of the core switch and reduce the user's investment cost. The use of MDC technology realizes the safe isolation of services.

Application requirements for cloud computing data centers

S12500G-AF series switches support VXLAN (Virtual eXtensible LAN) technology. VXLAN is a Layer2 VPN technology based on IP network and adopting "MAC in UDP" encapsulation. VXLAN can provide Layer2 interconnection for scattered physical sites based on existing service providers or enterprise IP networks, and can provide business isolation for different tenants.

S12500G-AF series switches support EVPN (Ethernet Virtual Private Network). EVPN is a Layer 2 VPN technology. The control plane uses MP-BGP to advertise EVPN routing information, and the data plane supports the use of VXLAN encapsulation to forward packets.

S12500G-AF series switches support the large-scale Layer 2 interconnection technology, which can realize the large-scale Layer 2 interconnection through EVPN+VXLAN, and realize the interconnection between multiple sites across the data center.

S12500G-AF series switches support FCoE (FC over Ethernet) technology; FCoE technology is mainly used to solve the heterogeneous problem of cloud computing data center LAN network and FC storage network. It can be realized through the deployment of FCoE and CEE technology. The integration of the front-end network and back-end network architecture of the data center solves the technical problems of the separation of data, computing and storage, thereby greatly reducing the cost of data center procurement and capacity expansion

S12500G-AF series switches support large-capacity ARP/ND, MAC, and ACL entries, which can adapt to the flat networking requirements of large data center networks.

Innovative multi-engine design

Innovative hardware design is adopted to provide the system with powerful control capability and 50ms high reliability guarantee through independent control engine, detection engine and maintenance engine.

Distributed control engine, all business boards provide a powerful control processing system, easily process various protocol messages and control messages, and support fine control of protocol messages, providing the system with a complete ability to resist protocol message attacks.

Distributed detection engine, all service boards can perform distributed BFD, OAM and other fast fault detection, and implement linkage with the control plane protocol, support fast protection switching and fast convergence, can achieve millisecond fault detection

Distributed maintenance engine, intelligent CPU system supports intelligent power management, and can support sequential power-on and power-off of single boards (reduce the power impact caused by simultaneous power-on of single boards, improve equipment life, reduce electromagnetic radiation, and reduce system power consumption)

DC-class HA

FFDR provides BFD and OAM functions to implement fast failover and convergence. The following lists the DC-class HA features:

BFD for VRRP/BGP/IS-IS/RIP/OSPF/RSVP/static routing

NSR/GR for OSFP/BGP/IS-IS/RSVP

Separation of control and data planes through independent control engine and switching fabric module.

1+1 redundancy for control engines

N+1 redundancy for switch fabric modules

1+1 redundancy for fan trays

N+M redundancy for power modules

HA—based on DRNI architecture

S12500G-AF series switches support DRNI (Distributed Resilient Network Interconnect) technology, which realizes cross-device link aggregation by virtualizing two physical devices into one device at the forwarding level, keeping the control plane independent of each other, and realizing dual-active access of the device. Provide equipment-level redundancy protection and traffic load sharing, while improving the reliability of the system.

Multi-level security protection

The S12500G-AF series switch use QoS policies to filter and limit traffic from data plane to control plane. During a DoS attack, the switch can identify and protect important packets and discard attack packets, ensuring normal operation

Supports a large numbers of ACLs while ensuring line-speed forwarding. ACLs can identify and control L2/IPv4/IPv6/MPLS traffic by using combinations of packet fields

Comprehensive maintenance and monitoring

Online state monitoring - Uses a dedicated engine to monitor the state of switch fabric modules, backplane channels, service communication channels, key chips, and storage. Once a failure occurs, it reports the failure to the system through EMS

Card isolation- Isolates specified cards from the forwarding plane. The isolated cards still work on the control plane, allowing the user to perform management operations such as real-time diagnosis and CPLD upgrade on the isolated cards without affecting system operation

Ethernet OAM- Provides multiple device-level and network-level fault detection methods

Green

Intelligent EMS engine system - Provides smart power management that supports sequential power-on and power-off and device status check. Sequential power-on and power-off reduces power impulse and electromagnetic radiation, and increases the lifetime of the device. Additionally, device status checks can isolate faulty and idle cards to reduce power consumption

Smart fan management- Collects fan temperature, calculates fan speed, and assigns the calculated speed to the fan tray. In addition, it detects fan speeds, fault alarms, and performs speed adjustment based on configuration sand area, reducing power consumption and noise, increasing the fan's lifetime

Internal interface monitoring-Automatically shuts down unused internal interfaces to reduce power consumption
