You can configure a VLAN that does not use the 802.1Q encapsulation protocol
used for trunking connections. Provide a VLAN ID number, and check Native
VLAN if you do not want the VLAN to use 802.1Q tagging.
If you want to use the 802.1Q tagging, leave the Native VLAN box unchecked.
Field Reference
Table 3-11 IP Address and Subnet Mask
Description
Enter a VLAN ID number from 1 to 4094. Cisco SDM displays a message
telling you to enter a different VLAN ID if the ID that you enter is already
in use.
If you do not want the VLAN to use 802.1Q tagging, check Native VLAN.
If you want the VLAN to use 802.1Q tagging, leave this box unchecked.
You can configure Layer 3 Ethernet interfaces for 802.1Q trunking or for basic
routing. If you configure the interface for 802.1Q trunking, you can configure
VLANs on the interface, and you can configure a native VLAN that does not use
the 802.1q encapsulation protocol. I f you configure the interface for routing, you
cannot configure subinterfraces or additional VLANs on the interface.
If you are configuring a Gigabit Ethernet interface for routing, you can provide
information about the switch module in this window. It is not required that you
provide this information.
You can provide an IP address and subnet mask for the switch module, and login
credentials required to log on to the the switch module interface.
