Chapter 7 Configuring the Switch Ports

Creating EtherChannel Port Groups

Port Group Restrictions on Static-Address Forwarding

These restrictions apply to entering static addresses that are forwarded to port groups:

• If the port group forwards based on the source MAC address (the default), configure the static

address to forward to all ports in the group. This method eliminates the chance of lost packets.

• If the port group forwards based on the destination address, configure the static address to forward

to only one port in the port group. This method avoids the possible transmission of duplicate

packets. For more information, see the “Adding Static Addresses” section on page 6-19.
