Determining the MAC address of your Internet gateway(s) depends on the type
of equipment you are using. Refer to your equipment’s User Manual for the
specific details.
You will need the MAC address of your gateways later to provision the secure
MAC white list of the APs configured in
secure port
mode.
Disabling or Enabling AP
Wireless Bridging
/interface/wifi-<n>-<m>/set ssid <ssid_index> wireless-bridge
{enabled|disabled}
Use the
show ssid table
command to determine
<ssid_index>
.
Disabling wireless bridging for an AP prevents wireless clients associated to that
particular AP from communicating with one another.
It does not prevent a wireless client associated with one AP (AP “A”) from
communicating with a wireless client associated with another AP (AP “B”). The
secure port
mode prevents this. See
“AP Secure Port Mode” on page 111
.
By default, wireless bridging is
enabled
.
Disabling Inter-AP
Wireless Client
Communication
Disabling inter-AP wireless client communications involves setting up a secure
MAC white list and enabling secure port mode for each AP.
Secure MAC White List
/interface/wifi-<n>-<m>/add secure-mac-address <mac-address-string>
[secure-mac-mask <mac-mask-string>]
[all | untagged | <vlan-id>]
/interface/wifi-<n>-<m>/del secure-mac-address <mac-address-string>
[all | untagged | <vlan-id>]
Use these commands only if you want to manually provision the MAC
addresses of the Internet gateway(s) or router(s) in your network.
These commands add and remove a MAC address from the secure MAC white
list. The MAC address can optionally be qualified with a mask and a traffic
descriptor as follows:
• The mask is specified with the
secure-mac-mask
option. Use
ff
to indicate
bits to accept. Use
00
to indicate bits to ignore. For example, a MAC
address of 00:0d:67:0c:21:90 with a mask of ff:ff:ff:00:00:00 specifies all MAC
addresses beginning with 00:0d:67. You can also customize the mask to
exactly suit your needs by using values other than
ff
or
00
.
• The traffic descriptor can be one of
all
,
untagged
or a VLAN ID. Use a
VLAN ID to specify the traffic of a particular VLAN. Use
untagged
to specify
only untagged traffic. Use
all
to specify all traffic.
When configured in secure port mode, the AP forwards to the associated
wireless clients only those Layer 2 (Ethernet) frames for which the source MAC
