Figure 47 Cable connections of an IRF virtual device in the non-aggregate mode with 2-port interface
cards
• When 2-port interface cards are adopted in an IRF virtual device with ports operating in the
aggregation mode, ports of MOD 1 can only be connected to ports of MOD 2, and the locations
of the ports of the interface cards are not limited.
Figure 48 Cable connections in an IRF virtual device in the aggregation mode with 2-port interface
cards
• 1-port interface cards do not support port aggregation in the IRF virtual device. When 1-port
interface cards are connected for an IRF virtual device, the port of MOD 1 can only be connected
to the port on MOD 2, as shown by callout 1 in Figure 49 ; when a 1-port interface card is
connected to a 2-port interface card for an IRF virtual device, the port of MOD 1 can only be
connected to the right port of the 2-port interface card, as shown by callout 2 in Figure 49 .
