Configuration Using the Command Line Interface (CLI)
Network Redundancy (CLI)
It is critical for industrial applications that the network remains running at all times. The ES9528 supports:
• Standard Rapid Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP)
The ES9528 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 about 10 ms for fail over for 100BASE-TX copper ports.
Other interfaces may take longer due to media characteristics.
• Rapid Dual Homing (RDH)
Advanced RDH technology allows the ES9528 to connect with a core managed switch easily and
conveniently. With RDH technology, you can also couple several Rapid Super Rings or RSTP groups
together, which is also known as Auto Ring Coupling.
Optionally, you can use the web user interface for configuration, see Network Redundancy on Page 70.
This table provides detailed information about the CLI command lines for network redundancy.
