show lacp system-identifier Displays the LACP system identifier for a device. 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. The default value is 32768 or configure a value between 1 and 65535. 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. OS10# show lacp system-identifier Actor System ID: Priority 32768, Address 90:b1:1c:f4:9b:8a Supported Releases 10.2.0E or later Link layer discovery protocol LLDP enables a LAN device to advertise its system and receive system information from adjacent LAN devices. • LLDP is enabled by default on OS10 interfaces. • An LLDP-enabled interface can support up to eight neighbors. An OS10 switch supports a maximum of 250 total neighbors per system. • OS10 devices receive and periodically transmit link layer discovery protocol data units (LLDPDUs), which are data packets. The default transmission interval is 30 seconds. • LLDPDU information received from a neighbor expires after the default time to live (TTL) value (120 seconds). • Spanning-tree blocked ports allow LLDPDUs. • 802.1X-controlled ports do not allow LLDPDUs until the connected device is authenticated. • Link layer discovery protocol-media endpoint discovery (LLDP-MED) is enabled on all interfaces by default. Protocol data units LLDP devices exchange system information represented as type, length, and value (TLV) segments: Type Length Value Information included in the TLV. Value (in bytes) of the TLV after the Length field. System information the agent is advertising. Layer 2 183
