Configuring Eais; Displaying And Maintaining Cfd - HP 5130 EI Series Configuration Manual

Configuring EAIS

You can configure EAIS on a device that does not support or is not configured with CFD. However, EAIS
must collaborate with the CFD function in the network, so you must configure CFD in the network.
For a port to send the EAIS frames, configure port status-AIS collaboration, and configure the correct
EAIS frame transmission level and interval. If you only enable port status-EAIS collaboration, but do not
configure the EAIS frame transmission level and interval, the port cannot send EAIS frames.
If you do not specify the VLANs where the EAIS frames can be transmitted, the EAIS frames will be
transmitted in the default VLAN of the current port. Otherwise, the EAIS frames will be transmitted in the
intersection of the following VLANs:
Specified VLANs where the EAIS frames can be transmitted.
•
VLANs to which the port belongs.
•
You can configure EAIS on the member port of an aggregation group, but the configuration does not take
effect. If you configure EAIS on the port and then add it to an aggregation group, the EAIS configuration
immediately fails to take effect. After the port leaves the aggregation group, the EAIS configuration takes
effect.
If the intersection of the configured VLANs where the EAIS frames can be transmitted and the VLANs to
which the port belongs is empty, no EAIS frame is sent. If the intersection contains more than 70 VLANs
and the EAIS frame transmission interval is 1 second, the CPU usage will be too high. In this case, HP
recommends that you set the EAIS frame transmission interval to 60 seconds.
To configure EAIS:
Step
1. Enter system view.
2. Enable
collaboration.
3. Enter
interface view or Layer 2
aggregate interface view.
4. Configure the EAIS frame
transmission level.
5. Configure the EAIS frame
transmission interval.
6. Specify the VLANs where the
EAIS
transmitted.

Remarks

By default, port status-AIS
collaboration is disabled.
N/A
By default, the EAIS frame
transmission level is not
configured.

transmission interval is not
configured.
By default, the EAIS frames can be
transmitted only within the default
VLAN of the port.
