Configuring for Network Management Applications LLDP (Link-Layer Discovery Protocol) system_cap For outbound advertisements, this TLV includes a bitmask of supported system capabilities (device functions). Also includes information on whether the capabilities are enabled. (Default: Enabled) For example, if you wanted to exclude the system name TLV from the outbound LLDP advertisements for all ports on a switch, you would use this command: ProCurve(config)# no lldp config 1-24 basicTlvEnable system_name If you later decided to reinstate the system name TLV on ports 1-5, you would use this command: ProCurve(config)# lldp config 1-5 basicTlvEnable system_name Configuring Support for Port Speed and Duplex Advertisements This feature is optional for LLDP operation, but is required for LLDP-MED operation. Port speed and duplex advertisements are supported on the switches covered in this guide to inform an LLDP endpoint and the switch port of each other's port speed and duplex configuration and capabilities. Configuration mismatches between a switch port and an LLDP endpoint can result in excessive collisions and voice quality degradation. LLDP enables discovery of such mismatches by supporting SNMP access to the switch MIB for comparing the current switch port and endpoint settings. (Changing a current device configuration to eliminate a mismatch requires intervention by the system operator.) 13-58
