show lacp system-identier
Displays the LACP system identier for a device.
Syntax
show lacp system-identifier
Parameters None
Default Not congured
Command Mode EXEC
Usage Information The LACP system ID is a combination of the congurable 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 congure 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 dierent for each device.

Link Layer Discovery Protocol
Link layer discovery protocol (LLDP) enables a local area network (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 supports up to eight neighbors. An OS10 switch supports a maximum of 250 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 of 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
Information included in the TLV.
Length Value in bytes of the TLV after the Length eld.
Value System information the agent advertises.
