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 ES7506 supports:
• Standard Rapid Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP)
The ES7506 supports RSTP versions IEEE 802.1D-2004, IEEE 802.1D-1998 STP, and IEEE 802.1w
RSTP.
• Redundant Ring
The Redundant Ring features 0 ms for restore and about 5 ms for fail over for copper.
• Rapid Dual Homing (RDH)
Advanced RDH technology allows the ES7506 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 65.
This table provides detailed information about the CLI command lines for network redundancy.
RSTP
Enable Switch(config)# spanning-tree enable
Disable Switch(config)# spanning-tree disable
RSTP mode
Switch(config)# spanning-tree mode rapid-stp
SpanningTree Mode change to be RST(802.1w).
STP mode
Switch(config)# spanning-tree mode stp
Spanning-Tree Mode change to be STP(802.1d).
Priority
Switch(config)# spanning-tree priority
<0-61440> valid range is 0 to 61440 in multiple of 4096
Switch(config)# spanning-tree priority 4096
Max Age
Switch(config)# spanning-tree max-age
<6-40> Valid range is 6~40 seconds
Switch(config)# spanning-tree max-age 10

Port Path Cost
Switch(config-if)# spanning-tree pathcost
method the pathcost is used to determine the best path between
devices
Switch(config)# spanning-tree pathcost method
long specifies 32-bit based values that range from 1-200,000,000
short specifies 16-bit based values that range from 1-65535
Switch(config-if)# spanning-tree pathcost 200000
