Configuring EAPS on a Switch
ExtremeWare XOS 11.0 Concepts Guide 185
The following command examples configure the hellotime value for the EAPS domain “eaps_1” to
2 seconds, the failtimer value to 15 seconds, and the failtimer expiry-action to open the secondary port
if the failtimer expires:
configure eaps eaps_1 hellotime 2
configure eaps eaps_1 failtime 15
configure eaps eaps_1 failtimer expiry-action open-secondary-port
Configuring the Primary and Secondary Ports
Each node on the ring connects to the ring through two ring ports. As part of the protection switching
scheme, one port must be configured as the primary port, and the other must be configured as the
secondary port.
If the ring is complete, the master node prevents a loop by logically blocking all data traffic in the
transmit and receive directions on its secondary port. If the master node subsequently detects a break in
the ring, it unblocks its secondary port and allows data traffic to be transmitted and received through it.
To configure a node port as primary or secondary, use the following command:
configure eaps <name> [primary | secondary] port <ports>
The following command example adds port 1 of the module installed in slot 8 of the BlackDiamond
switch to the EAPS domain “eaps_1” as the primary port.
configure eaps eaps_1 primary port 8:1
Configuring the EAPS Control VLAN
You must configure one control VLAN for each EAPS domain. The control VLAN is used only to send
and receive EAPS messages.
NOTE
A control VLAN cannot belong to more than one EAPS domain. If the domain is active, you cannot
delete the domain or modify the configuration of the control VLAN.
To configure the EAPS control VLAN for the domain, use the following command:
configure eaps <name> add control vlan <vlan_name>
NOTE
The control VLAN must NOT be configured with an IP address. In addition, only ring ports may be
added to this control VLAN. No other ports can be members of this VLAN. Failure to observe these
restrictions can result in a loop in the network.
NOTE
The ring ports of the control VLAN must be tagged.
By assigning the control VLAN a QoS profile of QP8 (with the QoS profile HighHi priority setting), you
ensure that EAPS control VLAN traffic is serviced before any other traffic and that control VLAN
