Switch Address Plan
The VLAN IDs and IP addresses designated for a switch and used throughout this document are not a
component of practices; they are only specified for the configuration examples. Your deployment will
have an IP address plan that suits your specific network.
In this document, all IP address ranges are /24 for the sake of simplicity. We recommend that VLAN IDs
be reused across the access switches deployed.
For example, in the access layer, VLAN 10 is always used for data, and VLAN 11 is always used for
voice. The IP subnets for those VLANs are different across the access switches, but the VLAN IDs are
the same. This type of address plan makes it easier to operate the network because the same VLAN IDs
are consistent.
Table 1 IP Address Plan
VLAN ID IP Address Server Description
100 192.168.1.0/24 — Switch in-band management VLAN.
10 192.168.10.0/24 Upstream device Access data VLAN for end devices
and subnet.
11 192.168.11.0/24 Upstream device Access voice VLAN for IP phones
and subnet.
12 192.168.12.0/24 Catalyst 3850 switch Access point VLAN and subnet.
200 192.168.13.0/24 Upstream device Wireless client VLAN and subnet.
— 192.168.254.0 — IP address range for all central

physically adjacent to the switch.
