3Com Switch 7750 Configuration Guide

914 CHAPTER 82: RRPP CONFIGURATION
■ Before creating an RRPP ring, you must create a control VLAN.
■ RRPP and loopback test functions are mutually exclusive. You must disenable
the loopback test on the primary/secondary port of the master/transit node and
the common/edge port of the edge node.
■ When deleting an RRPP domain by using the undo rrpp domain command,
make sure no RRPP ring exists in the RRPP domain.
■ The ring ID must be unique in the same RRPP domain.
Edge Node
Configuration Example
Network requirements
■ Define the switch as a node in RRPP domain 1.
■ Define VLAN 4092 as the control VLAN
■ Define the switch as a transit node on primary ring 1 in RRPP domain 1,
GigabitEthernet2/0/1 as the primary port, and GigabitEthernet2/0/2 as the
secondary port.
■ Define the switch as an edge node on subring 2 in RRPP domain 1, the port
GigabitEthernet2/0/2 as the common port, the port GigabitEthernet2/0/4 as
the edge port.
Configuration procedure
c
CAUTION: Make sure that the switch ports connecting the Ethernet rings have
been configured as trunk ports. All ports allow data VLAN packets to pass. And
STP has been disenabled on all the ports connecting the Ethernet rings.
