6 Address Table Settings
Switches store the addresses for all known devices. This information is used to pass
traffic directly between the inbound and outbound ports. All the addresses learned
by monitoring traffic are stored in the dynamic address table. You can also
manually configure static addresses that are bound to a specific port.
This chapter describes the following topics:
◆ MAC Address Learning – Enables or disables address learning on an interface.
◆ Static MAC Addresses – Configures static entries in the address table.
◆ Address Aging Time – Sets timeout for dynamically learned entries.
◆ Dynamic Address Cache – Shows dynamic entries in the address table.
◆ MAC Address Mirroring – Mirrors traffic matching a specified source address to
a target port.
◆ MAC Notification Traps – Issue trap when a dynamic MAC address is added or
removed.
Configuring MAC Address Learning
Use the MAC Address > Learning Status page to enable or disable MAC address
learning on an interface.
Command Usage
◆ When MAC address learning is disabled, the switch immediately stops learning
new MAC addresses on the specified interface. Only incoming traffic with
source addresses stored in the static address table (see “Setting Static
Addresses” on page 189) will be accepted as authorized to access the network
through that interface.
◆ Dynamic addresses stored in the address table when MAC address learning is
disabled are flushed from the system, and no dynamic addresses are
subsequently learned until MAC address learning has been re-enabled. Any
device not listed in the static address table that attempts to use the interface
after MAC learning has been disabled will be prevented from accessing the
switch.
