If 2-port interface cards are used and IRF links are aggregate, follow these guidelines on connecting two
neighboring switches:
 The ports on the interface card MOD 1 on one switch must connect to the ports on the interface
card MOD 2 on the other switch.
 A port on one interface card can connect to any port on the other interface card, as shown in Figure
44. For example, you can connect the left port on one interface card to the left or right port on the
other interface card.

If 1-port interface cards are used, follow these guidelines on connecting neighboring switches:
 If both of the switches use 1-port interface cards, the port on MOD 1 on one switch must connect to
the port on MOD 2 on the other switch (see callout 1 in Figure 45).
 If one switch uses a 1-port interface card but the other switch uses a 2-port interface card:
 If the 1-port interface card is in the MOD 1 slot, the port on the card must connect to the right
port on the 2-port interface card (see callout 2 in Figure 45.)
 If the 1-port interface card is in the MOD 2 slot, the port on the card must connect to the left port
on the 2-port interface card.
