LLDP
Configuring LLDP on the controller
17-5
Time to live
Indicates the length of time that neighbors will consider LLDP information sent by this agent
to be valid. Time to live is automatically calculated by multiplying Transmit interval by
Multiplier.
Generate dynamic system names
When enabled, this feature replaces the system name with a dynamically generated value
which you can define.
Controller name
Specify how the dynamically generated name will be created. You can use regular text in
combination with placeholders to create the name. Placeholders are automatically expanded
each time the name is regenerated.
If the placeholders cause the generated name to exceed 32 characters, it is truncated.
Placeholders
%RN: System name of the neighboring device to which the port is connected, obtained
via the System Name TLV. Since this is an optional TLV, if it is not available, the Chassis
ID TLV is used instead.
%RP: Port description of the port on the neighboring device to which the local port is
connected, obtained via the Port Description TLV. Since this is an optional TLV, if it is not
available, the Port ID TLV is used instead.
%SN: Controller’s serial number.
%IP: Controller’s IP address. An IP address can require up to 15 characters
(nnn.nnn.nnn.nnn).
Note When the LLDP agent is active on both the LAN port and the Internet port, the name
generated on the LAN port is used for both interfaces.
The dynamic name on the controller is only updated when a change is detected in the
neighbor to which a port is connected.
Once AP names are dynamically changed by this feature, there is no way to return to the
old AP names.
To define the suffix for APs, select Controlled APs >> Configuration > LLDP.
Expanded controller name
Shows the generated name with all placeholders expanded. To see the generated name you
must select Save, wait about 10 seconds, and then select the Refresh button in your
browser.
Update AP names every nn seconds
Specify the interval at which dynamic names for all controlled APs are updated.
