We are testing out a VSS solution to a customer who, against our STRONG recommendation will need to plug single-homed some servers into a pair of 6748-GE-TX that exist on VSS both chassis. The distance between the two boxes will be superior to 100m.
We are testing out the scenario where we have jumbo frames crossing the VSL between the two chassis, and we can't get past 1500byte frames.
I do understand and agree that the power of the VSS is on the MEC, but in case some machines are single-homed, and they send out unfragmentable jumbo frames to the network, they do not seem to get past the VSL link.
The IOS cli does not allow us to set the MTU on the VSL link.
Does anyone have any idea on how to achieve this?
