Link Aggregation Control Protocol (LACP) provides a method to control the
bundling of several physical ports together to form a single logical channel.
LACP allows a network device to negotiate an automatic bundling of links by
sending LACP packets to the peer (directly connected device that also imple-
ments LACP).
The Lightweight Directory Access Protocol is an application protocol for
reading and editing directories over an IP network.
A 16 bit address assigned to end nodes by the subnet manager
Each LID is unique within its subnet.
Link Layer Discovery Protocol (LLDP) is an industry standard protocol
designed to supplant proprietary Link-Layer protocols such as Extreme's EDP
(Extreme Discovery Protocol) and CDP (Cisco Discovery Protocol). The goal
of LLDP is to provide an inter-vendor compatible mechanism to deliver Link-
Layer notifications to adjacent network devices.
A Media Access Control address (MAC address) is a unique identifier
assigned to network interfaces for communications on the physical network
segment. MAC addresses are used for numerous network technologies and
most IEEE 802 network technologies including Ethernet.
The maximum size of a packet payload (not including headers) that can be
sent /received from a port.
Priority Based Flow Control applies pause functionality to traffic classes OR
classes of service on the Ethernet link.
Quality of service is the ability to manage different applications or users by
priority such that a required bit rate, delay, packet dropping probability, and/or
other measures may be guaranteed.
Ambient temperature sensor of the QSFP cage for the selected Leaf or Spine
module
Remote Authentication Dial In User Service. A networking protocol that
enables AAA centralized management for computers to connect and use a net-
work service.
Accessing memory in a remote side without involvement of the remote CPU.
Rapid Spanning Tree Protocol. A spanning-tree protocol used to prevent loops
in bridge configurations. RSTP is not aware of VLANs and blocks ports at the
physical level.
The interface for querying and manipulating subnet management data.
Secure Copy or SCP is a means of securely transferring computer files
between a local and a remote host or between two remote hosts. It is based on
the Secure Shell (SSH) protocol.
