(section 7.16.2 on page 827). 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 using the hellotime (section 7.16.3
on page 828) and failtime (section 7.16.4 on page 829) commands . The
hello-timer is the periodic time at which the master sends a health-check
packet, and the fail-time is the time the master 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. Use the port primary command (section
7.16.5 on page 830) to configure one port as the primary port; and the port
secondary command to configure the other as the secondary port.
5. Configure the EAPS Control VLAN (CVLAN): Use the control vlan
command (section 7.16.6 on page 831) to create the VLAN used to pass
ring integrity commands. 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.
Use the no control vlan command to release the CVLAN.
6. Configuring EAPS Protected VLANs (PVLAN): Use the protect vlan
command (section 7.16.7 on page 833) to create the protected VLANs that
carry normal traffic and are protected by the EAPS ring integrity mechanism.
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.
Note that the protected VLANs must be cleared prior to deleting an EAPS
Domain. Use the no protect vlan command to release the Protected
VLANs.
7. Enable or disable EAPS: Before enabling a domain as described in the next
step, first use the eaps command (section 7.16.9 on page 835) to globally
enable the EAPS function on the ECN330-switch. If EAPS has not yet been
enabled or has been disabled with the no eaps command, no EAPS
domains will work.
