Cisco Small Business SPA300 Series, SPA500 Series, and WIP310 IP Phone Administration Guide 144

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. The Cisco SPA525G/525G2 allows the administrator to set the switch

operational mode to auto-negotiation or to a specific speed/duplexity.

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:

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.
