Ethernet Automatic Protection Switching
messages reach their intended destinations. For example, if the control VLAN is not assigned the
highest priority and a broadcast storm occurs in the network, the control VLAN messages might be
dropped at intermediate points. Assigning the control VLAN the highest priority prevents dropped
control VLAN messages.
Because the QoS profile HighHi priority setting by itself should ensure that the control VLAN traffic
gets through a congested port first, you should not need to set the QoS profile minimum bandwidth
(
minbw) or maximum bandwidth (maxbw) settings. However, if you plan to use QoS (profile priority and
bandwidth settings) for other traffic, you might need to set a
minbw value on QP8 for control VLAN
traffic. Whether you need to do this depends entirely on your configuration.
The following command example adds the control VLAN “keys” to the EAPS domain “eaps_1”.
configure eaps eaps_1 add control vlan keys
Configuring the EAPS Protected VLANs
You must configure one or more protected VLANs for each EAPS domain. The protected VLANs are the
data-carrying VLANs.
NOTE
When you configure the VLAN that will act as a protected VLAN, the ring ports of the protected VLAN
must be tagged (except in the case of the default VLAN).
To configure an EAPS protected VLAN, use the following command:
configure eaps <name> add protect vlan <vlan_name>
NOTE
As long as the ring is complete, the master node blocks the protected VLANs on its secondary port.
The following command example adds the protected VLAN “orchid” to the EAPS domain “eaps_1.”
configure eaps eaps_1 add protect vlan orchid
Enabling and Disabling Fast Convergence
You enable Fast Convergence on the entire switch; this feature ensures convergence in less than 50
milliseconds.
To enable or disable Fast Convergence on the switch, use the following command:
configure eaps fast-convergence [off | on]
Enabling and Disabling an EAPS Domain
To enable a specific EAPS domain, use the following command:
enable eaps {<name>}
