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.

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-name cannot be ALL.

You cannot specify an EPSR instance using an epsr-name that is already 
configured. The epsr-name is 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.
