Catalyst 3850 - Interface Range - Behaviour

[keeganb2000]

I want to select a range of interfaces across 4 switches in a stack.

This command returns with the error "% Invalid input detected at '^' marker."

interface range Gi1/0/2 , Gi1/0/4 , Gi1/0/11 , Gi1/0/13 - 14 , Gi1/0/17, Gi1/0/20 - 21 , Gi1/0/23 , Fa2/0/1 - 2 , Fa2/0/4 - 24 , Fa3/0/1 - 24 , Fa4/0/1 - 5 , Fa4/0/7 - 13 , Fa4/0/15 - 24

I can however break up this string of interfaces into 3 which works, see below. Am I missing some fundamential understanding of how interface range selection works in the above command?

range 01

Gi1/0/2 , Gi1/0/4 , Gi1/0/11 , Gi1/0/13 - 14 , Gi1/0/17

range 02
Gi1/0/20 - 21 , Gi1/0/23 , Fa2/0/1 - 2 , Fa2/0/4 - 24

range 03
Fa3/0/1 - 24 , Fa4/0/1 - 5 , Fa4/0/7 - 13 , Fa4/0/15 - 24

The port range is very long, hence, the error message.

Thanks for the feedback. Do you know what the character limit is?

Not sure.  Could be 32 characters.

I recall many range statements are limited to five arguments (i.e. or four commas).
