Information About Global LLDP Commands

You can set global LLDP settings. These settings include the length of time before discarding LLDP information
received from peers, the length of time to wait before performing LLDP initialization on any interface, the
rate at which LLDP packets are sent, the port description, system capabilities, system description, and system
name.
LLDP supports a set of attributes that it uses to discover neighbor devices. These attributes contain type,
length, and value descriptions and are referred to as TLVs. LLDP supported devices can use TLVs to receive
and send information to their neighbors. Details such as configuration information, device capabilities, and
device identity can be advertised using this protocol.
The switch supports the following required management LLDP TLVs:
• Data Center Ethernet Parameter Exchange (DCBXP) TLV
• Management address TLV
• Port description TLV
• Port VLAN ID TLV (IEEE 802.1 organizationally specific TLVs)
• System capabilities TLV
• System description TLV
• System name TLV
