LLDP Overloading
LLDP adds information as LLDP and LLDP-MED TLVs into the LLDP packets. LLDP
overload occurs when the total amount of information to be included in a LLDP
packet exceed the maximum PDU size supported by an interface.
The LLDP Overloading page
displays the number of bytes of LLDP/LLDP-MED
information, the number of available bytes for additional LLDP information, and the
overloading status of every interface.
To view LLDP overloading information:
STEP 1 Click Administration > Discovery - LLDP > LLDP Overloading.
This page contains the following fields for each port:
• Interface—Port identifier.
