Important Points to Remember
• LLDP is enabled by default.
• Dell Networking systems support up to eight neighbors per interface.
• Dell Networking systems support 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.
• INTERFACE level configurations override all CONFIGURATION level configurations.
• LLDP is not hitless.
