What is IP aliasing?

IP Aliasing is a networking feature that allows you to assign multiple IP addresses to

a single NIC port. This is useful when StorEdge is replacing multiple servers. All of

the IP aliases for the selected NIC port must be on the same physical network and

share the same netmask and broadcast address as the first, or primary IP address

specified for the selected adapter. Up to nine alias IP addresses can be added to the

primary IP address of each NIC port. Therefore, a single network interface card with

two ports could provide up to 20 usable IP addresses.

Important – Alias IP addresses can only be added to NIC ports that are assigned a

primary role. There are three possible role options for the StorEdge NICs. They are:

primary, independent, and mirror. The primary NIC role is not to be confused with

the primary IP address. The primary NIC role is an assignment indicating how the

adapter will function in a system. The primary IP address is the first address

assigned to a selected adapter.

How do I set up IP aliasing?

1. Access the StorEdge via Telnet or serial console.

2. Press [Enter] at the [menu] prompt and enter the administrator password.

3. Select option “A”, “Host Name & Network”.

4. Find the page containing the desired network interface with the spacebar.

5. Select option “1”, “Edit fields”.

6. Use [Tab] or [Enter] to navigate to the IP Alias field for the desired NIC.

7. Select option “1”, “Setup”.

8. Enter an Alias IP for the NIC card.

9. Continue to enter alias IP addresses. If no more aliases are required, simply press

the [Enter] key.

10. System will return to setup screen.

11. Navigate to the end of the menu with [Tab] or [Enter].

12. Select option “7”, “Save changes”.
