By default, the ExtremeXOS software advertises the mandatory LLDP (Link Layer Discovery Protocol) TLVs (which are not configurable) and the optional system description TLV. For details, see Supported Advertisements (TLVs)). All other optional TLVs are not advertised.
You can choose to advertise or not advertise any optional TLV, but be aware that the total LLDPDU length, which includes the mandatory TLVs, cannot exceed 1500 bytes. Optional TLVs that cause the LLDPDU length to exceed the 1500-byte limit are dropped. You can see if the switch has dropped TLVs by referring to the EMS log or by issuing the show lldp statistics command.
The following sections describe configuration for the following types of optional TLVs.
