Link Layer Discovery Protocol (LLDP)

The IEEE 802.1AB defined standard, Link Layer Discovery Protocol (LLDP),
allows the switch to advertise major capabilities and physical descriptions.
This information can help you identify system topology and detect bad
configurations on the LAN.
For information about configuring LLDP, settings see "Discovering Network
Devices" on page 761.

Link Layer Discovery Protocol (LLDP) for Media Endpoint Devices

The Link Layer Discovery Protocol for Media Endpoint Devices (LLDP-
MED) provides an extension to the LLDP standard for network configuration
and policy, device location, Power over Ethernet management, and inventory
management.
For information about configuring LLDP-MED, settings see "Discovering
Network Devices" on page 761.

Connectivity Fault Management (IEEE 802.1ag)

NOTE:
This feature is available on the N4000 series switches only.
The Connectivity Fault Management (CFM) feature, also known as Dot1ag,
supports Service Level Operations, Administration, and Management
(OAM). CFM is the OAM Protocol provision for end-to-end service layer
instance in carrier networks. The CFM feature provides mechanisms to help
you perform connectivity checks, fault detection, fault verification and
isolation, and fault notification per service in a network domain.
For information about configuring IEEE 802.1ag settings, see "Configuring
Connectivity Fault Management" on page 859.

Priority-based Flow Control (PFC)

NOTE:
This feature is available on the N4000 switches only.
The Priority-based Flow Control feature allows the switch to pause or inhibit
transmission of individual priorities within a single physical link. By
configuring PFC to pause a congested priority (priorities) independently,
protocols that are highly loss sensitive can share the same link with traffic that
