Egress Protection
/interface/wifi-<n>-<m>/set backhaul protection-admin-state {enable|disable}
This command controls egress protection. The default setting is
disable
.
Egress protection provides extra redundancy for the BelAir20E’s egress point.
The egress point is the point where the BelAir20E’s access traffic leaves the
BelAir wireless network. This may be through an Ethernet connection, L2TP
tunnel end-point, or a cable modem.
If the egress point fails and egress protection is enabled, the BelAir20E uses a
Wi-Fi backhaul link to connect to another BelAir node so that traffic can leave
the BelAir wireless network through that node’s egress point. The BelAir20E
selects the best node to use based on several factors including signal strength
and the number of hops to the egress point.
Egress protection is revertive. If the original egress point becomes operational
again, the access data is redirected back to original egress point.
To use egress protection, make sure of the following:
• The BelAir20E and it surrounding nodes are equipped with appropriate
hardware to provide the Wi-Fi backhaul link.
• The channel number, privacy settings and link identifier are the same for all
surrounding nodes.
• The
backhaul protection-admin-state
option for the radios has been
enabled.
• The tunnel engine for the BelAir20E is enabled, if the egress point is an L2TP
