Description

create epsr

CREate EPSR=epsr-name MODE=MASTer CONtrolvlan={vlan-name|
1..4094} PRImaryport=port [HEllotime=time]
[FAilovertime=time2] [RIngflaptime=0..65535]

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

the switch. This name is a character string, 1 to 15 characters long. Valid

preserved for display purposes.
