Static and Dynamic MAC Address Tables

You can add static entries to the switch's MAC address table and configure

the aging time for entries in the dynamic MAC address table. You can also

search for entries in the dynamic table based on several different criteria.

For information about viewing and managing the MAC address table, see

"Managing the MAC Address Table" on page 849.

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 651.

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

For information about configuring LLDP-MED, settings see "Discovering

Network Devices" on page 651.

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

has different loss tolerances. Priorities are differentiated by the priority field

of the 802.1Q VLAN header. The PowerConnect 8000-series and 8100-series

switches support lossless transport of frames on up to two priority classes.

An interface that is configured for PFC is automatically disabled for 802.3x

flow control.
