I have a 40GB QSFP to 4x10GB SFP dac breakout cable which i want to use with cisco catalyst 9500-32QC switch.
Switch running on IOS XE software version 17.06.04 and IOS software [Bengaluru] catalyst L3 Switch Software (CAT9k_IOSXE), version 17.6.4. But however when i type "hw-module breakout" it showing error at breakout command.
When I type the command in from the global configuration the only options I get are "hw-module slot" & "hw-module subslot". The switch is not running stackwise-virtual. Is there anything that I am missing?
when i type the show interfaces status command, it shows the speed as 40G and detects the type of the cable too.
Solved! Go to Solution.

I raised a case with Cisco regarding this issue and they mentioned that catalyst 9500-32CQ switch has no capability of breakout as its designed only to function as core or distribution switch not as edge.

Hi
Take a look on this guide
"
Only the C9300-NM-2Q uplink module supports breakout cables. This module has two 40G slots with a QSFP+ connector in each slot.
To enable breakout for dual mode QSFP breakout cables, the hw-module breakout module slot port port-range switch switch-num command must be configured on the two uplink ports of the switch. The range for the variables in the hw-module breakout module slot port port-range switch switch-num command are given below:
slot — Slot number of port depending on the chassis model. This can be only 1.
port-range — Single port or range of ports on which breakout is configured. The range is from 1 to 2.
switch-num — Switch number in the stack. The range varies from 1 to 8.
See Configuring a Breakout Interface for the list of configurable interfaces."
