How To Configure EPSR
Modifying the Control VLAN
You cannot modify the control VLAN while EPSR is enabled. If you try to remove or add ports to the control VLAN, the switch generates an error message as follows:
Manager> delete vlan=1000 port=1
Error (3089409): VLAN 1000 is a control VLAN in EPSR and cannot be modified
Disable the EPSR domain and then make the required changes. Note that disabling EPSR will create a loop, so is not recommended on a network with live data. Of course, in a live network, you can manually prevent a loop by disconnecting the cable between any two of the nodes.
