Lldp Operation; Viewing The Lldp Configuration - Dell PowerEdge M IO Aggregator Command Reference Manual

LLDP Operation

On an Aggregator, LLDP operates as follows:
• LLDP is enabled by default.
• LLDPDUs are transmitted and received by default. LLDPDUs are transmitted periodically. The default
interval is 30 seconds.
• LLDPDU information received from a neighbor expires after the default Time to Live (TTL) value:
120 seconds.
• FTOS supports up to eight neighbors per interface.
• FTOS supports a maximum of 8000 total neighbors per system. If the number of interfaces multiplied
by eight exceeds the maximum, the system does not configure more than 8000.
• LLDP is not hitless.
