1/8/2018 Proprietary and Confidential - Technicolor 112
12 Isolation
By default, the Technicolor Wireless Gateway allows traffic to pass freely between CPE devices
on the same logical network. This behavior may not be desirable in certain types of deployments
where devices associating with the Wireless Gateway may belong to different
persons/households (examples: public hotspots, hotels, and multi-dwelling units). For these
deployments, the appropriate isolation modes should be enabled. This feature causes the
Wireless Gateway to block traffic sent between CPE devices.
12.1 User Provisioning for Isolation
No user provisioning is available for this feature. This feature must be provisioned by the
operator using SNMP.
12.2 SNMP Provisioning for Isolation
Isolation can be configured separately for any, and all of the following types of traffic:
• Traffic in which both the source and destination addresses are reachable via the same
primary or secondary BSSID (WLAN-WLAN traffic)
Isolation for WLAN-WLAN traffic:
Isolation for WLAN-WLAN traffic is controlled via the tchRgDot11BssApIsolation MIB object.
This is an interface-specific MIB which must be appended with the appropriate interface index of
the BSSID that is being configured for isolation.
This means that different BSSIDs may have different isolation settings. For example, it is
possible to leave isolation disabled on the primary BSSID, while setting up a secondary BSSID
for hotspot services that has isolation enabled.
The default setting for this MIB is integer 0 (disabled) for all SSIDs. To enable WLAN-WLAN
traffic isolation, set this MIB to 1 (enabled).
This setting is effective in the device configuration file as well as when set via SNMP (If set via
SNMP, the setting will persist across device reboots). If SNMP is used, setting
tchRgDot11ApplySettings to true (1) is required for the change to take effect (as is the case
with other tchRgDot11 MIB settings when set via SNMP).
