CAUTION:
■
The control VLAN of an RRPP domain cannot be a static VLAN already created
on the switch. If you configure a dynamic VLAN as the control VLAN of an
RRPP domain, the VLAN becomes a static VLAN automatically.
■
You are not recommended to configure a VLAN as both an RRPP control VLAN
and a remote-probe VLAN. (Refer to “Mirroring Configuration” on page 685
for information about remote-probe VLAN.)
■
You are not recommended to configure a VLAN as both an RRPP control VLAN
and an isolate-user-VLAN/sub VLAN. (Refer to “Isolate-User-VLAN
Configuration” on page 113 and “Configuring a Sub VLAN” on page 122.)
■
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.
Master 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 the master node on primary ring 1 in RRPP domain 1,
GigabitEthernet2/0/1 as the primary port, and GigabitEthernet2/0/2 as the
secondary port.
■
Set the Hello timer and Fail time to 2 seconds and 7 seconds respectively.
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.
