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
82. F
or 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 83).
• 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 83.)
{ 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.
