46.3 MAC Forwarding
Use this screen to view and configure to which MAC addresses and ports the Switch should forward the
incoming NLB traffic.
Click SWITCHING > NLB > MAC Forwarding to display the screen as shown.
Note: The following screens cannot have duplicate settings as the SWITCHING > NLB > MAC
Forwarding screen.
• SWITCHING > Static MAC Forwarding
• SWITCHING > Multicast > Static Multicast Forwarding By MAC
• SWITCHING > Static MAC Filtering
Figure 255 SWITCHING > NLB > MAC Forwarding
The following table describes the labels in this screen.
MAC Address Enter a multicast or unicast MAC address added in the SWITCHING > NLB > MAC Forwarding
screen.
The last binary bit of the first octet pair in a multicast MAC address must be 1. For example, the
first octet pair 00000001 is 01 and 00000011 is 03 in hexadecimal, so 01:00:5e:00:00:0A and
03:00:5e:00:00:27 are valid multicast MAC addresses.
The last binary bit of the first octet pair in a unicast MAC address must be 0. For example, the
first octet pair 00000000 is 00 and 00000010 is 02 in hexadecimal, so 00:00:5e:00:00:0A and
02:00:5e:00:00:27 are valid unicast MAC addresses.
Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to
save your changes to the non-volatile memory when you are done configuring.
Clear Click Clear to clear the fields to the factory defaults.
Cancel Click Cancel to not save the configuration you make and return to the last screen.
