127 — Port-VLAN
ID
Untagged VLAN to which a port belongs.
127 — Protocol
identity
Not supported.
802.3 Organizationally-specific TLVs
127 — MAC/PHY
configuration/
status
Indicates duplex and bit rate capability and the current duplex and bit rate settings of the sending device.
Also indicates whether the current settings are due to auto-negotiation or due to manual configuration.
127 — Power via
MDI
Not supported.
127 — Maximum
frame size
Maximum frame size capability of the MAC and PHY.
Media endpoint discovery
LLDP media endpoint discovery (LLDP-MED) provides additional organizationally-specific TLVs to allow endpoint devices and
network connectivity devices to advertise their characteristics and configuration information.
LLDP-MED endpoint devices are located at the IEEE 802 LAN network edge and participate in IP communication service using
the LLDP-MED framework, such as IP phones and conference bridges. LLDP-MED network connectivity devices provide access
to the IEEE 802-based LAN infrastructure for LLDP-MED endpoint devices, such as IP phones. An OS10 device acts as an
LLDP-MED network connectivity device.
LLDP-MED provides network connectivity devices to:
● Manage inventory
● Manage PoE
● Identify physical location
● Identify network policy
NOTE:
Only the Rx function is supported for managing PoE and identifying the physical location. LLDP-MED is designed for
but not limited to VoIP endpoints.
Network connectivity device
OS10 can acts as an LLDP-MED network connectivity device (Type 4). Network connectivity devices transmit an LLDP-MED
capability TLV to endpoint devices and store information that endpoint devices advertise.
127/1 — LLDP-
MED capabilities
● If the transmitting device supports LLDP-MED
● What LLDP-MED TLVs are supported
● LLDP device class
127/2 — Network
policy
Application type, VLAN ID, L2 priority, and DSCP value.
127/3 — Local
identification
Physical location of the device expressed in one of three formats:
● Coordinate-based LCI
● Civic address LCI
● Emergency call services ELIN
127/4 —
Extended power-
via-MDI
Power requirements, priority, and power status.
