Industrial Managed Switches: Function Overview

Several Options:

• Configuration via Web-Based Management
• Configuration via command line (SSH, Telnet, RS-232)
• Network management via SNMP v1, v2, v3
• Support of MIB standards (Management Information Base)
• Diagnostics via Modbus TCP: Numerous information available for easy diagnostics via MODBUS

• Automatically detects a connected SFP module
• Detailed module information
• Real-time monitoring
  - Temperature
  - Power supply
  - Transmission power
  - Reception power

Simplified Maintenance:

• Port mirroring: Mirroring the network traffic
• LLDP: Automatic detection of adjacent devices
• Email notifications

• Typical switching time < 300 ms (depends on the application)
• Extremely easy configuration
• Up to 20 participants (fast aging) in a jet ring

Xpress Ring:

• Switching time < 20 ms
• Easy configuration
• Up to 200 switches in one Xpress ring
• Two Xpress rings per switch

Dual Ring:

• Combination of both redundancy types
• 1 jet ring and 1 Xpress ring per switch or 2 Xpress rings per switch

The Fast and Open Solution:

• Standardized and open technology
• Switching time < 50 ms
• Nested topologies with up to six rings per switch
• Realization of a one-fault tolerance (SPOF – Single Point of Failure)

ERPS – Enhancement Mode:

• WAGO's devices with integrated switches and fast aging configuration
• Typical switching time < 300 ms (depends on the application)

The Security Standard of IT Networks: Secure authentication and authorization in ETHERNET networks (locally on the switch or via RADIUS server).

Process:

• Authentication of a subscriber is performed by the authenticator.
• The authenticator checks the authentication information of the subscriber (supplicant) with an authentication server.

Authorization only for the required services

Filtering data packets due to:

• a source MAC or source IP address
• a destination MAC or destination IP address
• a range of MAC or IP addresses
• UDP/TCP source or destination ports

• Dynamically learns MAC addresses per port
• Limitation of MAC addresses per port
• MAC-based white/black list per port

VLAN (e.g., per IEEE 802.1Q)

Segmentation in logical, virtual networks:

• Broadcast limitation
• Security improvement
• Data flow prioritization
• Subdivision of machines and office networks, for example

• Routing of data packets between VLANs via IP address
• Communication from one participant to two or more VLANs
• Economic connection of networks to higher-level routers
• Prioritization of data packets via IP address

• Assignment of data packets to a VLAN via MAC address
• Prioritization of data packets via MAC address

LACP link aggregation

Merge multiple data connections into a single logical link:

• Increase transmission rate
• Link redundancy

• Faster transfer of important data packets through the switch
• Prioritization of data packets per IEEE 802.1 Q
• Limitation of the bandwidth or number of packets per unit of time per port
• Increase in data transmission quality

• Stopping broadcast storms
• Ensuring network availability
• Limitating broadcast and multicast data flows (packets/time)
