Switch Management and Operating Concepts
Additional IP Interfaces
To add an IP interface to the switch, you must first configure a VLAN and then associate an IP address (subnet mask and gateway) with the VLAN. These
•They cannot use BOOTP/DHCP to get a dynamic IP address. They must be assigned a manual IP address.
•They can be renamed. However, when the change is applied, all other settings for the IP interface are changed to their default values. This includes the settings for RIP and the IP multicast protocols.
IP Addressing Scheme
An IP addressing scheme must be established and implemented when the IP interfaces are set up on the switch.
For example:
VLAN Name | VID | Switch Ports |
|
|
|
System (default) | 1 | 5, 6, 7, 8, 21, 22, 23, 24 |
|
|
|
Engineering | 2 | 9, 10, 11, 12 |
|
|
|
Marketing | 3 | 13, 14, 15, 16 |
|
|
|
Finance | 4 | 17, 18, 19, 20 |
|
|
|
Sales | 5 | 1, 2, 3, 4 |
|
|
|
Backbone | 6 | 25, 26 |
|
|
|
In this case, six IP interfaces (or six subnets) are required, so a CIDR notation of 10.32.0.0/11 (or a
A10.xxx.xxx.xxx IP address notation provide six network addresses. For example:
VLAN Name | VID | Network Address |
|
|
|
System (default) | 1 | 10.32.0.0 |
|
|
|
Engineering | 2 | 10.64.0.0 |
|
|
|
Marketing | 3 | 10.96.0.0 |
|
|
|
Finance | 4 | 10.128.0.0 |
|
|
|
Sales | 5 | 10.160.0.0 |
|
|
|
Backbone | 6 | 10.192.0.0 |
|
|
|
The six 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 form.
IP interfaces consist of two
Each IP interface listed above provides a maximum of 2,097,150 unique IP addresses per interface (assuming the 10.xxx.xxx.xxx notation).
