NETGEAR 8800 User Manual Note: The MAC-based VLAN netlogin parameter applies only for the NETGEAR 8800 series switches. See Chapter 16, Network Login for more information on netlogin. With no options, the command displays all FDB entries. (The age parameter does not show on the display for the backup MSM/MM on modular switches; it does show on the display for the primary MSM/MM.) Displaying FDB Statistics To display FDB statistics, use the following command: show fdb stats {{ports {all | } | vlan {all} | {vlan} } {no-refresh}} With no options, the command displays summary FDB statistics. MAC-Based Security MAC-based security allows you to control the way the FDB is learned and populated. By managing entries in the FDB, you can block and control packet flows on a per-address basis. Note: MAC-based security is not supported on BlackDiamond 20800 series switches in this software release. MAC-based security allows you to limit the number of dynamically-learned MAC addresses allowed per virtual port. You can also "lock" the FDB entries for a virtual port, so that the current entries will not change, and no additional addresses can be learned on the port. You can also prioritize or stop packet flows based on the source MAC address of the ingress VLAN or the destination MAC address of the egress VLAN. Note: For detailed information about MAC-based security, see Chapter 17, Security. This section describes the following topics: • Managing MAC Address Learning on page 280 • Managing Egress Flooding on page 281 • Displaying Learning and Flooding Settings on page 282 Chapter 10.
