Manual switch (MS) is an operator-initiated process, configured by means of the manual-switch command, that manually blocks a desired port in a ring. You need to explicitly specify the VLAN, Ethernet slot, and port from the desired device.
The following example configures and clears a manual switch.
device# configure terminal device(config)# erp 1 device(config-erp-1)# manual-switch vlan 5 ethernet 0/1
Use the no manual-switch command to remove the manual switch mechanism.
