• It mirrors traffic that passes through a switch port or VLAN to another port for traffic analysis.
• It prevents traffic on a LAN from being disrupted by a broadcast storm.
• It protects the switched network from receiving BPDUs on ports that should not be receiving them.
• It copies traffic that passes through a switch interface and sends the data directly to a syslog or SNMP server for analysis.
• It inspects voice protocols to ensure that SIP, SCCP, H.323, and MGCP requests conform to voice standards.
• It mitigates MAC address overflow attacks.
