Description This command creates an EPSR instance. Note that ingress filtering is automatically applied to a port when the port is added as an EPSR. The port’s ingress setting is then unchangeable unless it is deleted from EPSR by destroying the last EPSR instance that includes that particular port.

The following configuration rules apply when creating an EPSR:

■The maximum number of EPSR instances that can be created on a switch is 16.

■The control VLAN must have exactly two member ports, except where there are a group of trunked ports that count as a single port. The ports, which must be tagged for the VLAN, will be used as the ring’s ports of the EPSR instance.

■The control VLAN cannot be part of another EPSR instance as either a control or data VLAN.

■If trunked ports are included as a ring port, as long as one of the trunked ports is up, the ring port is considered to be, up. SNMP traps and log messages will display the lowest number port as the ring port's port number for the trunk.

■Ports enabled for LACP, STP, GARP or VLAN Assignment cannot be added to an EPSR instance.

Parameter	Description
EPSR	The name of the Ethernet protected switch ring instance being created on
	the switch. This name is a character string, 1 to 15 characters long. Valid
	characters are uppercase and lowercase letters, digits, the underscore, and
	the hyphen. The epsr-namecannot be ALL.
	You cannot specify an EPSR instance using an epsr-namethat is already
	configured. The epsr-nameis not case sensitive, although its case is
	preserved for display purposes.
	Default: no default
MODE	Determines whether the device is acting as a master node or a transit node.
	Default: master
	MASTer	Sets the switch to be the master node for the named EPSR
		ring.
	TRANsit	Sets the switch to be a transit node for the named EPSR ring.
