Once enabled, each link aggregate can be viewed as a single logical link
of multiple physical ports with only one IP and MAC address. HP-APA
can aggregate up to four physical ports into one link aggregate; the
number of link aggregates allowed per system is 50. Empty link
aggregates will have zero MAC addresses.
You can aggregate the ports within a multi-ported networking card
(cards with up to four ports are currently available). Alternatively, you
can aggregate ports from different cards. Figure 3-19 shows two
examples.
Figure 3-19 Aggregated Networking Ports
Both the Single and Dual ported LANs in the non-aggregated
configuration have four LAN cards, each associated with a separate
non-aggregated IP address and MAC address, and each with its own
LAN name (lan0, lan1, lan2, lan3). When these ports are aggregated all
four ports are associated with a single IP address and MAC address. In
