Make sure all interfaces in a VLAN are configured for jumbo frames before configuring jumbo frame support on an SVI. A packets MTU is not checked on the ingress side of an SVI. However, it is checked on the egress side of an SVI. If the packets MTU is larger than the egress SVIs MTU, the packet is fragmented by software (if the DF bit is not set), which results in poor performance. Software fragmentation only happens for L3 switching. When a packet is forwarded to an L3 port or an SVI with a smaller MTU, software fragmentation will occur.
