Supported TLVs
ExtremeWare XOS 11.3 Concepts Guide
151
NOTE
To avoid exceeding the 1500-byte limit, Extreme Networks recommends sending information on only one or two
VLANs on the LLDP port. Any TLVs that exceed the limit are dropped.
The following TLVs are enabled by default when LLDP transmit is enabled on a port:
●
Chassis ID
●
Port ID
●
Time to live
●
System description
●
End-of-LLDP PDU
All of these TLVs that are sent by default are mandatory for the protocol and cannot be disabled, except
the system description. You can configure the system not to advertise the system description when
LLDP is enabled; the other four TLVs cannot be configured not to advertise.
Table 18 lists all the defined
TLVs, if they are included by default once you enable LLDP, if they can be configured, if they are
mandatory or optional, and if you can repeat that TLV in one LLDP packet.
NOTE
Refer to ExtremeWare XOS Command Reference Guide for complete information on configuring LLDP using the CLI.
