Syntax Parameters Default Command Mode Usage Information Example show lacp system-identifier None Not configured EXEC The LACP system ID is a combination of the configurable LACP system priority value and the MAC address. Each system that runs LACP has an LACP system priority value. Configure a value between 1 and 65535. The default value is 32768. LACP uses the system priority with the MAC address to form the system ID and uses the system priority during negotiation with other devices. A higher system priority value means a lower priority. The system ID is different for each device.

LLDP devices advertise its capabilities in the form of LLDP data units (LLDPDUs). LLDP-MED is an LLDP enhancement that enables endpoint devices and network connected devices to advertise their characteristics and configuration information. LLDP-MED network connected devices such as switches provide access to the IEEE 802-based LAN infrastructure for LLDPMED endpoint devices, such as IP phones. OS10 switch acts as an LLDP-MED network connected device. ● By default, LLDP and LLDP-MED are enabled on the interfaces. NOTE: You cannot configure LLDP-MED on the management interface. ● An LLDP-enabled interface supports up to eight neighbors. OS10 switch supports a maximum of 250 neighbors per system. ● OS10 switches periodically transmit LLDPDUs. The default transmission interval is 30 seconds. ● OS10 switches receive LLDPDU information from a neighbor. The information expires after a specific amount of time, called time to live (TTL). The default TTL value is 120 seconds. ● OS10 switches allow LLDPDUs in spanning-tree blocked ports. ● OS10 switches do not allow LLDPDUs in 802.1X-controlled ports until the connected device is authenticated. LLDPDU is a sequence of type, length, and value (TLV). ● Type - Contains the TLV type. ● Length - Size of the value field, in bytes. ● Value - Contains the capability information of the device to be advertised.
