used as the index for this domain in EAPS database. When deleting an
EAPS Domain, first release the Control VLAN (CVLAN) and Protected
VLANs (PVLANs) configured on this domain (as described in Step 6 and 7).
If a port on the domain ring has not been added to another domain ring, this
port will be reset to operate as a normal port. The database of this domain
will then be cleared.
2. Define the EAPS mode of the ECN330-switch: After creating an EAPS
domain, define the EAPS mode for this node (EAPS Domain Configuration -
EAPS Mode, section 6.11.2 on page 265). Only one node can be defined as
the master node on a domain ring, all the other ports should be defined as
transit nodes.
3. Configure EAPS polling timers: Set the values of the polling timers the
master node uses for the EAPS health-check packet that is circulated
around the ring for an EAPS domain (EAPS Domain Configuration - Hello
Timer and Fail Timer, section 6.11.2 on page 265). The hello-timer is the
periodic time at which the master node sends a health-check packet, and
the fail-time is the time the master node waits to receive back a health-check
packet from the other direction in the ring.
4. Configure the primary and secondary ports: Each node on the ring connects
to it through two ring ports. Configure one port as the primary port and the
other as the secondary port (EAPS Domain Configuration - Primary Port
and Secondary Port, section 6.11.2 on page 265).
5. Configure the EAPS Control VLAN (CVLAN): Specify the VLAN used to
pass ring integrity commands (EAPS Domain Configuration - Control VLAN,
section 6.11.2 on page 265). The CVLAN is automatically assigned a QoS
profile of Qp8 (with the QoS High priority setting). The CVLAN must NOT be
configured with an IP address. In addition, only ring ports may be added to
the CVLAN. No other ports can be members of this VLAN. Also, the ring
ports of the CVLAN must be tagged. Failure to observe these restrictions
can result in a loop in the network.
Note that the CVLAN must be cleared prior to deleting an EAPS Domain.
To release the CVLAN, clear the check box in the Control VLAN field.
6. Configuring EAPS Protected VLANs (PVLAN): Specify the protected
VLANs that carry normal traffic and are protected by the EAPS ring integrity
mechanism (EAPS Domain Protected VLAN Configuration , section 6.11.2
on page 265). One EAPS domain can be assigned 10 VLANs – 1 control
VLAN and 9 protected VLANs. The ring ports of a protected VLAN must be
tagged. The protected VLANs will be blocked on the secondary port.
