/interface/wifi-<n>-<m>/set ssid <ssid-number> ap-oos-identifier

<oos_string>

/system/set ap-oos-broadcast-delay <oos_delay>

/interface/wifi-<n>-<m>/set ap-oos-broadcast {enabled|disabled}

[option {replace|prepend}]

/system/show ap-oos-broadcast-delay

These commands let you modify the SSIDs of a radio with an out-of-service

string when a node loses its egress connection for longer than the period

specified by

<oos_delay>

. The out-of-service string can be prepended to the

existing SSID or it can replace the existing SSID. The out-of-service string can

contain up to 14 characters. The default string is

outOfService..

and by default

it replaces the SSID.

The out-of-service delay (<oos_delay>) ranges from 30 to 300 seconds. The

default is 300 seconds. The out-of-service delay is set for the entire BelAir20E.

Use the

/system/show ap-oos-broadcast-delay

command to display the current

delay.

When a node’s egress connection is declared out-of-service, the node also

applies WPA AES encryption with a 16-character pre-shared key to all SSIDs

except for the default management SSID. This is to to prevent a user from

accidently connecting to an open SSID which is in out-of-service. The

16-character pre-shared key consists of the first 10 characters of the

out-of-service identifier followed by the last six digits of the node’s MAC

address. If the out-of-service identifier is less than 10 characters, then period

characters (.) are used to complete the first 10 characters of the pre-shared

key.

The status of a node's egress connection is determined as follows:

1 If a tunnel is enabled, the egress status is the tunnel's status.

2 If a tunnel is not enabled and there is a cable modem in the system, the

egress status is the modem's status.

3 If a tunnel is not enabled and there is no cable modem in the system, the

egress status is the Ethernet link's status.
