ZESR Single-Domain Multi-Ring Configuration Example
Figure 5-40
to F are configured with a ZESR domain, which contains a primary ring and a secondary
ring. This is called single-domain multi-ring configuration.
Purpose
l
The control VLAN of the ZESR domain is VLAN 4000, and the protection instance is
instance 1 (including VLANs 100 to 110).

Function
l
Configures the ZESR restart time (s).
Default: 120.
Restart-time: the ZESR initialization
time during the device startup. During
this period, all ports in the ZESR ring are
in Blocking state.
Configures not to send a TCN packet in
a designated ZESR domain. By default,
a ZESR domain is configured to send
TCN packets.
A TCN packet is a packet sent when the
topology changes in the STP network.
Currently it is ZESR that triggers STP
to send TCN packets. In the ZESR and
STP hybrid networking environment, in
order for the STP network to perceive
the topology change of the ZESR
network, ZESR is required to send TCN
packets to the STP network when it
detects the topology change.
Configures to enable or disable the TCN
packet sending function on a port. By
default, a port is configured not to send
TCN packets.
Only in the condition that the TCN packet
sending function is enabled both in a
ZESR region and on the corresponding
port in that region, the corresponding
port will send out TCN packets when the
ZESR ring state changes.
