Operation Manual – RRPP
H3C S3610&S5510 Series Ethernet Switches
Caution:
It is recommended to configure the primary ring first and then the subring when you
configure an RRPP domain. Moreover, a Ring ID cannot be applied to more than
one RRPP ring in one RRPP domain.
If a device lies on multiple RRPP rings in an RRPP domain, only one primary ring
exists. The device serves as either an edge node or an assistant edge node on the
subrings.
The total number of rings configured on a device in all RRPP domains should not be
greater than 16.
Modification of node mode, port role and ring level of an RRPP ring is prohibited
after configuration. If needed, you must first delete the existing configuration.
The secondary port on the master node and a port on a subring node must not be
configured as a multi-domain intersection common port, and the two ports that
access the same node to the same RRPP ring must not be configured as
multi-domain intersection common ports at the same time.
When configuring multi-domain intersecting rings, do not enable or disable the
RRPP ring on which the multi-domain intersection common port resides with RRPP
globally enabled.
In the case of multi-domain intersection, the rings in different domains are
independently configured. Each single domain can contain multiple rings, among
which there must be one and only one primary ring. The data VLAN in one domain
must be isolated from the data VLAN in another.
The ports accessing an RRPP ring must conform to the following conditions:
Trunk port;
Layer 2 Ethernet port or Layer 2 GE port;
Except for aggregation port, loopback port and mirroring destination port;
Port with STP, QinQ, 802.1x, MAC address authentication, voice VLAN and IP
Source Guard disabled;
Do not enable OAM remote loopback function on an RRPP port. Otherwise, this
may cause temporary broadcast storm;
