The Nortel Ethernet Routing Switch 5500 Series (E1), running in Layer 2 mode, is configured with one port-based VLAN and one MultiLink Trunking (MLT) group for the aggregate uplink ports. The Nortel Ethernet Routing Switch 5500 Series switches (R1 and R2) are configured with backup master enabled so that both switches can reply to ARP.
