Bit 10—100BASE-TX full duplex mode
•
Bit 15—Unknown
•
Bit 10, 11, 13 and 14 should be set.
The value for 2 octets operational MAU type should be set to reflect the real operational MAU type:
16—100BASE-TX full duplex
•
15—100BASE-TX half duplex
•
11—10BASE-T full duplex
•
10—10BASE-T half duplex
•
For example, in most cases, the phone is set to 100BASE-TX full duplex. The value 16 should then be
set. The TLV is optional for a wired network and not applicable for a wireless network. The phone will
send out this TLV only when in wired mode. When the phone is not set for auto-negotiation but specific
speed/duplexity, for the outgoing LLDPDU TLV, bit 1 for the octet value auto-negotiation support/status
should be clear (0) to indicate auto-negotiation is disabled. The 2 octets PMD auto-negotiation
advertised capability field should be set to 0x8000 to indicate unknown.
LLDP-MED Capabilities TLV
For the outgoing LLDPDU, the TLV should have the device type 3 (End Point Class III) and with the
following bits set for 2-octet Capability field:
Bit Position
0
1
4
5
For the incoming TLV, if the LLDP-MED TLV is not present, the LLDPDU is discarded. The
LLDP-MED Capabilities TLV is mandatory and only one is allowed for the outgoing and incoming
LLDPDUs. Any other LLDP-MED TLVs will be ignored if they present before the LLDP-MED
Capabilities TLV.
Network Policy TLV
Outgoing LLDPDU—Before the VLAN or DSCP is determined, the Unknown Policy Flag (U) is set to
1. If the VLAN setting or DSCP is known, the value is set to 0. When the policy is unknown, all other
values are set to 0. Before the VLAN is determined or used, the Tagged Flag (T) is set to 0. If the tagged
VLAN (VLAN ID > 1) is used for the phone, the Tagged Flag (T) is set to 1. Reserved (X) is always set
to 0. If the VLAN is used, the corresponding VLAN ID and L2 Priority will be set accordingly. VLAN
ID valid value is range from 1-4094. However, VLAN ID=1 will never be used (limitation). If DSCP is
used, the value range from 0-63 is set accordingly.
Incoming LLDPDU—Multiple Network Policy TLVs for different application types are allowed.
