I've got a Cisco 3750X stack pair and "show system mtu" reports:
System MTU size is 1500 bytes
System Jumbo MTU size is 9000 bytes
Routing MTU size is 1500 bytes
Everything I've read suggests that this means I've got Jumbo Frames enabled. However, there is nothing in my running config to say that this has been set (although I've read that the "system mtu jumbo 9000" won't appear anyway, but no explanation as to why this is the case).
Please could someone confirm if my understanding is correct? We don't currently have Jumbo Frames setup on our hosts and I don't want to enable it only to find I missed something on the switch.
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
