Port assignments for ISLs

ISL usage notes for Cisco 3132Q-V and Cisco 3232C switches​

ISL connections can be done either with the 40 Gbps (Cisco 3132Q-V) or 40/100 Gbps (Cisco 3232C or 9336C) using ports 15—20, or using breakout cables with ports 21—24. A separate breakout cable is required for each ISL connection. The switch ports that support breakout mode are divided into four logical ports. For example, physical port 21 is logically split into four ports:

• 21/1

• 21/2

• 21/3

• 21/4

ISL port usage​

When using only two ISL ports per switch (Broadcom or Cisco), you can use any four ports as long as they are the same speed.
