Is it necessary to change the MTU for SVL links in a scenario in which interfaces are configured with MTU larger than default 1500 bytes?Traffic could flow between chassis through SVL links in a Stackwise Virtual cluster. Could not find any reference...

In a mixed 9300L/9300LM stack, is Stack-T3A cable compatible with C9300L-STACK-KIT connector? Conversely, is Stack-T3 cable compatible with C9300L-STACK-KIT2 connector?

Since both, 9300L and 9300LM uses StackWise-320, is mixed stacking of 9300L and 9300LM switches supported?

I know that Cisco Secure Firewall ISA3000 supports OT protocols, like MMS, modbus, DNP3. Does other series of Firepower appliances (1000, 2100, 4100 etc) also support these OT protocols?Is there a tool or document where we can find the protocols disc...

I received an 9300LM and can say that the connectors are mechanically incompatible. Stack-T3A cable will NOT plug into C9300L-STACK-KIT adapter port, and STACK-T3 cable will not plug into C9300L-STACK-KIT2 adapter port.

@Giuseppe Larosa , TAC excused themselves from giving the technical reasons. It must be a very good and an unavoidable reason because Cisco put existing 9300L customers in a very difficult situation.

I would like to warn everyone that the C9300L-STACK-KIT2 used by C9300LM uses a cable that is incompatible with C9300L-STACK-KIT which is offered to C9300L switches. Therefore, it is not possible to simply add a C9300LM into an existing C9300L stack ...

I decided to be increase the MTU globally (system mtu 9216). This changed the SVL interfaces to 9216 automatically, and I am sure that there will be no issues with jumbo frames traversing these links.

Thanks. Does this mean that System MTU needs to be changed in a scenario in which ports with MTU larger than 1500 bytes is necessary?
