We have four cat6509 that are uplinked to each other with L2 802.1q trunks.
We have a non-routed vlan that we use for a cluster interconnect.
Jumbo frames should be enabled.
So we set the mtu xxxx command on the ports where the cluster interfaces of the servers are connected.
It doesnt seem to work.
Probably because I have not set a bigger mtu on the uplink ports.
I am afraid that my network will crash because no-one else uses/can use jumboframes on my network.
So my question:
is it possible to change the mtu only for a vlan? not the entire trunk with all my production vlans on it.
