3. LLDP MED Link Layer Discovery Protocol for Media Endpoint Devices is an extension of LLDP intended for managing endpoint devices such as Voice over IP phones and network switches The LLDP MED TLVs advertise information such as network policy power via MDI inventory management and device location details The LLDP and LLDP MED information can be used by SNMP applications to simplify troubleshooting enhance network management and maintain an accurate network topology gt LLDPDU Format Each LLDPDU includes an ordered sequence of three mandatory TLVs followed by one or more optional TLVs plus an End of LLDPDU TLV as shown in the figure below Chassis ID TLV Port ID TLV TTL TLV and End TLV are the four mandatory TLVs for a LLDPDU Optional TLVs provide various details about the LLDP agent advertising them and they are selected by network management M mandatory TLV required for all LLDPDUs The maximum length of the LLDPDU shall be the maximum information field length allowed by the particular transmission rate and protocol In IEEE 802 3 MACs for example the maximum LLDPDU length is the maximum data field length for the basic untagged MAC frame 1500 octets gt LLDP Working Mechanism 1 LLDP Admin Status The transmission and the reception of LLDPDUs can be separately enabled for every port making it possible to configure an implementation to restrict the port either to transmit only or receive only or to allow the
4. BPDU Filter BPDU filter function is to prevent BPDUs flood in the STP network If a switch receives malicious BPDUs it forwards these BPDUs to the other switched in the network which may result in spanning trees being continuously regenerated In this case the switch occupying too much CPU or the protocol status of BPDUs is wrong With BPDU filter function enabled a port does not receive or forward BPDUs but it sends out its own BPDUs Such a mechanism prevents the switch from being attacked by BPDUs so as to guarantee generation the spanning trees correct 76 Choose the menu Spanning Tree STP Security Port Protect to load the following page Port Protect Select d d 1 F 2 F 3 4 F 5 F E T F 8 F z F 10 F 11 F 12 F 13 F 14 F 15 Fot Loop Protect Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable RootProtect TC Protect BRDU Protect BPD Filter LAG Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable Disable LAG Disable Disable Disable Disable LAG Disable Disable Disable Disable LAG Disable Disable Disable Disable LAG Disable Disable Disable
