3.3.5 Channel Sharing
NOTE: The channel
sharing function
is absent from CLI set
options and show radio
output on Mesh Points
that do not support it.
On ES820-35, ES2440-35, ES2440-3555, ES2440-3444 and
ES2440-3444m model Mesh Points that are enabled for
FastPath Mesh bridging (described in Section 3.2.2), you can
combine certain of their internal radios into a single virtual
bridging radio by enabling channel sharing.
In certain deployments, such virtual channel-sharing radios can
provide superior coverage and/or mobility for network bridging
links.
NOTE: Changing
sharing requires
you to reboot the Mesh
Point (see Section 5.2).
Channel sharing is disabled by default.
When channel
sharing is enabled on dual radio Mesh Points
that support the function (the ES820-35 and ES2440-35),
Radio 1 and Radio 2 are combined to form a single virtual
radio, configured with a single
set radio command set. When
channel
sharing is enabled on four-radio Mesh Points that
support it (the ES2440-3555 and ES2440-3444), Radio 2,
Radio 3, and Radio 4 are combined in this way.
Because a virtual radio created through channel sharing is
configured through a single
set radio command set, identical
configuration parameters are applied simultaneously to all of
the radios included in the virtual radio.
NOTE: A virtual
radio created
through channel
shar-
ing
can be used only for
network bridging.
Like their common radio settings, the single bridging BSSs
configured on radios combined through channel sharing must
be identically configured. To facilitate this, when you
add a
new BSS to the virtual radio, the BSS is replicated
automatically on each of the radios that comprise the channel-
sharing virtual radio. Any subsequent changes to this virtual
combined BSS will likewise be extended to the configurations
of each actual BSS that comprises it.
Channel sharing is limited to Unlicensed National Information
Infrastructure (UNII)-3 channels in the 5 GHz-band:
149–165,
when not on a 4.4 GHz radio.
View the current
sharing setting with show sharing.
# show sharing
Disabled
The default channel sharing setting on all platforms is
Disabled , in which state Mesh Point radios function
independently. Use
set sharing to enable or disable channel
sharing on Mesh Point radios.
# set sharing disable|enable
As command output informs you, you must reboot the Mesh
Point in order for a change to channel
sharing to take effect.
# set sharing enabled
[OK] This change will not take effect until the system is rebooted.
# reboot
