Table 5-12. VLAN Example – Assigned Ports
In this case, 6 IP interfaces are required, so a CIDR notation of
10.32.0.0/11 (or a 11-bit) addressing scheme will work. This
addressing scheme will give a subnet mask of
11111111.11100000.00000000.00000000 (binary) or
255.224.0.0 (decimal).
Using a 10.xxx.xxx.xxx IP address notation, the above example
would give 6 network addresses and 6 subnets.
Any IP address from the allowed range of IP addresses for each
subnet can be chosen as an IP address for an IP interface on
the switch.
For this example, we have chosen the next IP address above
the network address:
VLAN Name VID Network Address IP Address
System (default) 1 10.32.0.0 10.32.0.1
Engineering 2 10.64.0.0 10.64.0.1
Marketing 3 10.96.0.0 10.96.0.1
Finance 4 10.128.0.0 10.128.0.1
Sales 5 10.160.0.0 10.160.0.1
Backbone 6 10.192.0.0 10.192.0.1
