Re: protocol type & ethertype

Hi Abbas,

I am asking about protocol type code e.g

R1(config)#access-list 200 permit ?
  <0x0-0xFFFF> Protocol type-code.

During LAB exam , if questions comes to configure access-list based upon
ethertype or protocol type code ,how will we configure it if we don't
remember these ethertypes & protocol type code . I suppose it is not
present in Doc CD .

Regards,
Shekhar
