8-port Gigabit Ethernet Switch User’s Guide

An example is presented below:
VLAN Name VID Switch Ports
System (default) 1 5
Engineering 2 6, 7
Marketing 3 8
Finance 4 2
Sales 5 3
Backbone 6 4
Table 5-5. 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 for the IP interface’s IP 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
Table 5-6. VLAN Example – Assigned IP Interfaces
The 6 IP interfaces, each with an IP address (listed in the table above), and a subnet mask of 255.224.0.0 can be entered
into the Setup IP Interface menu.
Spanning Tree Protocol
The IEEE 802.1D Spanning Tree Protocol allows for the blocking of links between switches that form loops within the
network. When multiple links between switches are detected, a primary link is established. Duplicated links are blocked
from use and become standby links. The protocol allows for the duplicate links to be used in the event of a failure of the
primary link. Once the Spanning Tree Protocol is configured and enabled, primary links are established and duplicated
links are blocked automatically. The reactivation of the blocked links (at the time of a primary link failure) is also
accomplished automatically – without operator intervention.
