Appendix A: IP Address Configuration

Overview

Using commands on the console, you can change the IP address of the Nasuni Edge Appliance. For example, you might want to change the IP address if you do not want to use the initial default IP address, or if the current IP address is not valid. Also, if you make an entry error when setting network parameters, you can correct it using the IP address configuration commands in this section.

You can also use console commands to change network device and system parameters, change static IP address, enable DHCP networking, and view the MAC Address for the Nasuni Edge Appliance Hardware Appliance.

setall static
Press Enter. The setall static command runs:
Figure A-10: setall static command.
1. To change the IP address, enter a new IP address and press Enter. To leave the current IP address unchanged, press Enter.
2. To change the netmask, enter a netmask and press Enter. To leave the current netmask unchanged, press Enter.
3. To change the MTU, enter an MTU and press Enter. To leave the current MTU unchanged, press Enter.
  The maximum transmission unit (MTU) is the size (in bytes) of the largest protocol data unit that the layer can pass onwards. A larger MTU brings greater efficiency, because each packet carries more user data while protocol overheads, such as headers, remain fixed; the resulting higher efficiency means a slight improvement in the bulk protocol throughput. A larger MTU also means processing fewer packets for the same amount of data. However, large packets can occupy a slow link for some time, causing greater delays to following packets, and increasing lag and minimum latency.
4. To change any of the above values, enter yes, then use step a, step b, and step c to change the values.
  Alternatively, to leave the values unchanged, enter No or press Enter.
5. To change the hostname, enter a new hostname and press Enter. To leave the current hostname unchanged, press Enter.
6. To change the default gateway, enter a default gateway and press Enter. To leave the current default gateway unchanged, press Enter.
7. To change the DNS server, enter one or two DNS servers separated by spaces and press Enter. To leave the current DNS server unchanged, press Enter.
8. To change the search domain, enter one or more search domains separated by spaces and press Enter. To leave the current search domain unchanged, press Enter.
9. To change any of the above values, enter yes, then use step e, step f, step g, and step h to change the values.
