I have a C9300-24T which needs to have its IOS updated. Its currently running v16.12.4. In the meantime, i need to set the MTU size on a switch interface. The usual "mtu xxxx" and "ip mtu xxxx" commands appear to be missing/invalid. Do you know what...
I have a catalyst 9300 switch running 17.12.04. When NTP is configured, it can see its two sources. But it incorrectly lists them as being stratum 16. eg;
#sh ntp assoc
address ref clock st when poll reach delay offset disp~10.70.240.40 .TIME. 16 - ...
I have a topology that will look like: san1 - switch1 - switch2 - san2.
The SANs are HPE Alletra using FC. The Alletra requires its san to san replication ports (RCFC) to use a different zone from its host to SAN ports. That seems straightforward.

I have 2 ISR 4431 configured to establish an L2TP tunnel over ipsec through my internal network. The aim is to stretch a vlan so it is accessible from a remote location. Here is the topology
Client (2.2.2.9/24) -- (2.2.2.2/24)router(3.3.3.1/24) --...
I have need to present a given single vlan on two C9300 switches separated by a layer 3 network. The presentation should be bidirectional and transparent. What would be the best kind of vpn setup to use?

Issue was the switch is communicating through an out of band interface using vrf vrf-mgmt. I needed to factor that into the ntp config.
Further to OP:
address ref clock st when poll reach delay offset disp~172.16.143.252 .TIME. 16 - 64 0 0.000 0.000 15937.~172.16.143.253 .TIME. 16 - 64 0 0.000 0.000 15937.
Its curious that your time sources are listed as stratum 16. Is that correct? ...
When the c9300 first came out, i was disappointed to learn that a firmware update takes down the whole stack. Other vendors do individual updates of stack members, whilst keeping the stack alive, with ease. I had hoped that there would be a reliable ...
Indeed the machine cert is available. However the customer is requiring that an individual user cert be present before a client can be permitted to connect to the corporate wifi proper.
