[c-nsp] VLAN Tagging/Untagging overhead

[Arie Vayner (avayner)]

Kris,

There should not be a big impact as if you are doing CEF switching the
layer 2 adjacency header is pre-computed and is just reused.

Hi All,

Is there any cpu impact by packets being de/encapsulated onto a VLAN
rather
than going as native on a software based platform (7200/7300)?

If so would this be a big impact at 50k pps?

Regards,
Kris
