Step Command Remarks
2. Enter interface
view or port group
view.
•
Enter Layer 2 Ethernet interface
view:
interface interface-type
interface-number
•
Enter port group view:
port-group manual
port-group-name
Use either command.
Settings in Layer 2 Ethernet interface view
take effect on the interface only. Settings in
port group view take effect on all member
ports in the port group.
3. Configure the
MAC learning limit
on the interface or
port group.
mac-address max-mac-count count
No MAC learning limit is configured by
default.
Layer 2 aggregate interfaces do not support
this command.
NOTE:
Do not configure the MAC learning limit on any member ports of an aggregation group. Otherwise, the
member ports cannot be selected.
Enabling MAC address roaming
After you enable MAC address roaming on an IRF fabric, each member switch advertises learned MAC
addresses to other member switches.
As shown in
Figure 6 , Device A and Device B form an IRF fabric enabled with MAC address roaming.
They connect to AP C and AP D, respectively. When Client A associates with AP C, Device A learns the
MAC address of Client A and advertises it to the member switch Device B.
Figure 6 MAC address tables of devices when Client A associates with AP C
If Client A roams to AP D, Device B learns the MAC address of Client A and advertises it to Device A to
ensure service continuity for Client A, as shown in Figure 7 .
