66 Switch Features
Port Mirroring
Port mirroring monitors and mirrors network traffic by forwarding copies of
incoming and outgoing packets from up to four source ports to a monitoring
port. The switch also supports flow-based mirroring, which allows you to copy
certain types of traffic to a single destination port. This provides flexibility—
instead of mirroring all ingress or egress traffic on a port the switch can mirror
a subset of that traffic. You can configure the switch to mirror flows based on
certain kinds of Layer 2, Layer 3, and Layer 4 information.
For information about configuring port mirroring, see "Monitoring Switch
Traffic" on page 391.
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 837.
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 659.
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 659.
