Configuring Security, Quality, and Network Features Configuring VLAN Settings 5 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 autonegotiation 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: Bit Position 0 1 4 5 Capability LLDP-MED Capabilities Network Policy Extended Power via MDI-PD Inventory 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.
