is one piece episode 268 filler?

Luffy being surrounded by thousands of Marines is cornered on a cliff, when the Big Bazooka units fire at him making him fall off. The Marines find Luffy hanging off the cliff and try to make him fall to his death by stepping on his fingers, but the cliff collapses and Luffy starts running on top of the falling Marines.

The Marines who did not fall tries to shoot down Luffy while he runs away. Zoro and Sanji are arguing which one of them is better.
