Network Redundancy
It is critical for industrial applications that the network remains running at all times. The ES8510 supports:
• Standard Rapid Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP)
The ES8510 supports RSTP versions IEEE 802.1D-2004, IEEE 802.1D-1998 STP, and IEEE 802.1w
RSTP.
• Multiple Spanning Tree Protocol (MSTP)
MSTP implements IEEE 802.1s, which uses RSTP for rapid convergence, enables VLANs to be grouped
into a spanning-tree instance, with each instance having a spanning-tree topology independent of other
spanning-tree instances. This architecture provides multiple forwarding paths for data traffic, enables
load balancing, and reduces the number of spanning-tree instances required to support a large number of
VLANs. MSTP was originally defined in the IEEE 802.1s and later merged into the IEEE 802.1Q-2003
specification.
• Redundant Ring
The Redundant Ring features 0 ms for restore and less than 5 ms for fail over for copper.
• Rapid Dual Homing (RDH)
Advanced RDH technology allows the ES8510 to connect with a core managed switch easily. With RDH
technology, you can also couple several Rapid Super Rings or RSTP groups together, which is also known
as Auto Ring Coupling.
The following pages are included in this group:
• STP Configuration on Page 72
• STP Port Configuration on Page 73
• STP Information on Page 74
• MSTP Configuration on Page 76
• MSTP Port Configuration on Page 79
• MSTP Information on Page 80
• Redundant Ring on Page 82
• Redundant Ring Information on Page 83
• Loop Protection on Page 84
Optionally, you can use the CLI to configure these features, see Network Redundancy (CLI) on Page 148.
