6 Configure the MAC address flushing method for the DHL session using the dhl num mac-flushing
command and specify either the raw or mvrp parameter option. By default, the MAC flushing method is
set to none. For example, the following command selects the MVRP method:
-> dhl 10 mac-flushing mvrp
7 Configure two links (linkA and linkB) for the DHL session using the dhl num linka linkb command.
Specify the ports identified in Step 1 as linkA and linkB. For example:
-> dhl 10 linka linkagg 5 linkb port 1/1/10
8 Select VLANs from the set of VLANs created in Step 2 and map those VLANs to linkB using the dhl
num vlan-map linkb command. Any VLAN not mapped to linkB is automatically mapped to linkA. By
default, all VLANs are mapped to linkA. For example, the following command maps VLANs 11-20 to
linkB:
-> dhl 10 vlan-map linkb 11-20
9 Administratively enable the DHL session using the dhl num admin-state command. For example:
-> dhl 10 admin-state enable
