C HAPTER 36 | ERPS Commands
– 1137 –
◆ If a port channel (static trunk) is specified as a ring port, it can not be
destroyed before it is removed from the domain configuration.
◆ A static trunk will be treated as a signal fault, if it contains no member
ports or all of its member ports are in signal fault.
◆ If a static trunk is configured as a ring port prior to assigning any
member ports, spanning tree will be disabled for the first member port
assigned to the static trunk.

COMMAND USAGE
◆ The RPL neighbor node, when configured, is a ring node adjacent to the
RPL that is responsible for blocking its end of the RPL under normal
conditions (i.e., the ring is established and no requests are present in
the ring) in addition to the block at the other end by the RPL Owner
Node. The RPL neighbor node may participate in blocking or unblocking
its end of the RPL, but is not responsible for activating the reversion
behavior.
◆ Only one RPL owner can be configured on a ring. If the switch is set as
the RPL owner for an ERPS domain, the west ring port is set as one end
of the RPL. If the switch is set as the RPL neighbor for an ERPS domain,
the east ring port is set as the other end of the RPL.
◆ The east and west connections to the ring must be specified for all ring
nodes using the ring-port command. When this switch is configured as
the RPL neighbor, the east ring port is set as being connected to the
RPL.
◆ Note that is not mandatory to declare a RPL neighbor.
