Create a Management VLAN in Hardware

Earlier you assigned an IP address to the interface for VLAN 100. Refer to the
a Management IP Address on an In-Band Interface"
However, merely assigning the IP address to VLAN 100 does not create the VLAN in hardware. Perform
the below step to make the switch reachable through the assigned IP address.
Configure a management VLAN in hardware and configure an uplink interface as a member of this
Step 13
VLAN.
This is an intermediate step required only to make the switch Layer 3 reachable and manageable from
Note
SSH or HTTPS as well as the console or Express Setup. You can skip this step if you continue to use the
console to complete the configuration, but required if you use another tool to complete the configuration
of the switch. The complete best-practice configuration for uplink connectivity is explained in the
"Uplink Interface Connectivity"
We recommend that you use a dummy VLAN as the native VLAN on trunk interfaces instead of the
default VLAN 1. Because all interfaces are assigned to VLAN 1 by default on the switch, this step limits
the traffic associated with potential user configuration and possible connection errors propagating across
the trunk.
All other VLANs on the uplink interfaces are tagged with IEEE 802.1q which encapsulates the Layer 2
head of the Frame packet.
The following example shows how to configure VLAN IDs in hardware and assign the names. The
upstream interfaces to the switch or router are modified to make them members of the new VLANs. You
must have the same VLAN ID on both ends of the Ethernet link to properly configure the management
VLAN in hardware. A "dummy" VLAN is used as the native VLAN on trunk interfaces. A dummy
VLAN is not used for data or management traffic.
