• Secondary Port – Shows the secondary port on this node.

EAPS Domain Configuration
• Control VLAN – The Control VLAN (CVLAN) is used only to send and
receive EAPS ring maintenance messages.
Only one CVLAN can be configured in an EAPS domain. First create the
VLAN to be used as the CVLAN (see “Creating VLANs” on page 284),
and then add the CVLAN to the EAPS domain.
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.
Once the domain has been activated by setting the Domain Status to
Enabled, the configuration of the Control VLAN cannot be modified. The
Domain Status must first be set to Disabled to stop the EAPS domain
before making any configuration changes to this VLAN.
• Primary Port – This port is open on the Protected VLAN and is used for
passing both control messages and data traffic. The master node sends
control messages from this port. (Range: Port 1-27)
Each node must connect to the ring through two ports as part of the
protection switching scheme – one port as the primary port and another
as the secondary port.
The primary port must be removed from an EAPS domain before
specifying a new primary port.
• Secondary Port – This port is blocked on the Protected VLAN and is
used only to receive control messages on the master node.
