Netgear XCM8806 - 8800 SERIES 6-SLOT CHASSIS SWITCH 사용자 설명서

The MAC-based VLAN netlogin parameter applies only for the 

NETGEAR 8800 series switches. See 

 

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 | <port_list>} | vlan {all} | {vlan} <vlan_name> } 

{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.

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. 

For detailed information about MAC-based security, see 

.
