AT-9000 Switch Command Line User’s Guide
Section X: Network Management 879
The switch does not verify whether a device connected to a port is LLDP-
compatible prior to sending mandatory and optional LLDPs.
Optional LLDP-
MED TLVs
LLDP-MED is an extension of LLDP used between LAN network
connectivity devices, such as this switch, and media endpoint devices
connected to them, such as IP phones.
LLDP-MED uses the LLDP advertisement, transmission and storage
mechanisms, but transmits, receives, and stores data specifically related
to managing the voice endpoint devices. This includes information about
network policy, location, hardware configuration, and, for Power over
Ethernet-capable devices, power management.
LLDP-MED TLVs, unlike the other TLVs, are only sent if the switch detects
that an LLDP-MED activated device is connected to a port. Otherwise,
LLDP-MED TLVs are not transmitted.
Note
The AT-9000 Switch is not an LLDP-MED activated device. The
switch, while capable of transmitting LLDP-MED TLVs to other
devices, cannot provide LLDP-MED information about itself.
The LLDP-MED TLVs are listed in Table 85.
Maximum frame size The maximum frame size the port can
forward.
