Cisco 220 Series Smart Plus Switches Command Line Interface Reference Guide Release 1.0.0.x
To specify how to handle LLDP packets when LLDP is globally disabled, use the
lldp lldpdu Global Configuration mode command.
Syntax
lldp lldpdu {bridging | filtering | flooding}
Parameters
• bridging—Bridges LLDP packets (bridging LLDP PDU to VLAN member
ports) when LLDP is globally disabled.
• filtering—Filters (deletes) LLDP packets when LLDP is globally disabled.
• flooding—Floods (forwards) LLDP packets to all interfaces when LLDP is
globally disabled.
Default Configuration
LLDP packets are flooded when LLDP is globally disabled.
Command Mode
Global Configuration mode
User Guidelines
If the STP mode is set to MSTP, the LLDP packet-handling mode cannot be set to
flooding. The STP mode cannot be set to MSTP if the LLDP packet-handling mode
is flooding. If LLDP is globally disabled, and the LLDP packet-handling mode is
flooding, LLDP packets are treated as data packets with the following exceptions:
• VLAN ingress rules are not applied to LLDP packets. LLDP packets are
trapped on all ports for which the STP state is Forwarding.
• Default deny-all rules are not applied to LLDP packets.
• VLAN egress rules are not applied to the packets. LLDP packets are
flooded to all ports for which the STP state is Forwarding.
• LLDP packets are sent as untagged.
