QinQ

For at aktivere VLAN tagging skriver man i global configuration[1]

vlan dot1q tag native

På interfacet definerer vi at alt trafik skal i vlan 130, men at den indre tag skal bibeholdes, og der skal klistres en ny på.

interface FastEthernet 0/0
 switchport access vlan 103
 switchport mode dot1q-tunnel

Begrænsninger

Configuring a port as an IEEE 802.1Q tunnel port has these limitations:

  • IP routing and fallback bridging are not supported on tunnel ports.
  • Tunnel ports do not support IP ACLs.
  • If an IP ACL is applied to a trunk port in a VLAN that includes tunnel ports, or if a VLAN map is applied to a VLAN that includes tunnel ports, packets received from the tunnel port are treated as non-IP packets and are filtered with MAC access lists.
  • Layer 3 quality of service (QoS) ACLs and other QoS features related to Layer 3 information are not supported on tunnel ports.

For more information about configuring IEEE 802.1Q tunnel ports, see the software configuration guide for this release.
