mixed stacking C9300

[Leo TI]

Hello friends

I have a question, can I do stacking between 9300-48t-a and 9300-24s-a? If that is possible, then I understand that they must have the same licensing level, but I could do a stack between 9300-48t-a and 9300-24s-e. I saw some Advantage features that only work with Essential.

@Leo TI ,

in the Cisco 9300 datasheet we can see details about stacking options:

Table 5.        Supported stacking options

Model	Stacking support	Stacking bandwidth support	Optional Stacking hardware	Number of members	Supported stack members
C9300X SKUs	StackWise-1T	1 Tbps	StackWise cable	8	Stacks with other Catalyst 9300X models at StackWise-1T speeds with same license level Stacks with C9300 SKUs at StackWise-480 speeds with same license level
C9300 SKUs	StackWise-480	480 Gbps	StackWise Cable	8	Other C9300 SKUs with same license level C9300 higher scale SKUs only stack with other like higher scale models
C9300L SKUs	StackWise-320	320 Gbps	C9300L-STACK-KIT Or C9300L-STACK-KIT2	8	Stacks with other Catalyst 9300L and 9300LM models with same license level
C9300LM SKUs	StackWise-320	320 Gbps	C9300L-STACK-KIT2	8	Stacks with other Catalyst 9300L and 9300LM models with same license level

Mixed stacking between Catalyst 9300X and Catalyst 9300 models are supported at StackWise-480 speeds.

Mixed stacking between Catalyst 9300 and Catalyst 9300X and Catalyst 9300 higher scale models (C9300-24UB, C9300-24UXB, C9300-48UB) is not supported. You cannot stack fixed uplink models (C9300L SKUs) with modular uplink models (C9300 SKUs) or other Catalyst switches, e.g. Cisco Catalyst 3850 and 3650 Series. Any combination of Catalyst 9300 models can form a stack. Separately, any combination of Catalyst 9300L models can form a stack.

Catalyst 9300 higher scale SKUs (C9300-24UB, C9300-24UXB, C9300-48UB) need to be stacked with other higher scale models.

StackWise cables that are available to configure stacking with Catalyst 9300 Series modular uplink models (C9300X and C9300 SKUs) come in lengths of 0.5m, 1m and 3m.

The optional StackWise-320 kit for Catalyst 9300 Series fixed uplink models (C9300L and 9300LM SKUs) consists of two stack adapters and a stacking cable. The default stacking cable is 0.5 m, but options of 1m and 3m are also available. Table 6 lists the stacking accessories.

Yes, I read the data sheet but it is not clear to me if the example I propose is feasible.

It's feasible with StackWise-480:

C9300 SKUs

StackWise-480

480 Gbps

StackWise Cable

8

Other C9300 SKUs with same license level C9300 higher scale SKUs only stack with other like higher scale models

You have 9300-48t-a and 9300-24s-a which are Catalyst 9300 SKUs.

The following are restrictions for your switch stack configuration:

• Only homogenous stacking is supported, that is, a stack of Cisco Catalyst 9300 Series Switches stack with only Cisco Catalyst 9300 Series Switches as stack members.

  Cisco Catalyst 9300L Series Switches stack with only Cisco Catalyst 9300L Series Switches as stack members.

  C9300-24UB, C9300-24UXB, and C9300-48UB switches can only be stacked with each other.

• You cannot have a switch stack containing a mix of different license levels.

Also the switches should be running the same version of IOS.
