what is the significance of the "in and out" parameters on the access-group command applied to the SVI?

SVI + ACL

  • Out—Traffic that has already been through the router           and leaves the interface. The source is where it has been, on the other side of           the router, and the destination is where it goes.

  • In—Traffic that arrives on the interface and then           goes through the router. The source is where it has been and the destination is           where it goes, on the other side of the router.

  • Inbound —If the access list is inbound, when the           router receives a packet, the Cisco IOS software checks the criteria statements           of the access list for a match. If the packet is permitted, the software           continues to process the packet. If the packet is denied, the software discards           the packet.

  • Outbound—If the access list is outbound, after the           software receives and routes a packet to the outbound interface, the software           checks the criteria statements of the access list for a match. If the packet is           permitted, the software transmits the packet. If the packet is denied, the           software discards the packet.
