Description
Lock address table: Use the z to toggle field values. Yes prevents
the switch from learning new MAC addresses. Any existing addresses that
the switch has learned remain in the address table.
MAC address aging: Set the regularity at which the switch scans its MAC
address table to determine the age of entries.
Configure IGMP snooping: Sets Internet Group Management Protocols
(IGMP) options for multimedia applications, such as desktop video
conferencing, that use IP multicast addresses.
Configure permanent MAC address: Allows permanent mapping
between a network device and a port.
Configure Port Security: Configures the switch ports so only authorized
devices can access a particular port.
Configure MAC address filtering: Allows the switch to drop unwanted
traffic.
Configure Ethernet multicast filtering: Blocks or forwards traffic over
each port for Ethernet (MAC-based) multicast groups.
