ARP-Ping IP Address Assignment
Each Opengear console server ships configured with a default IP Address 192.168.0.1 Subnet Mask 255.255.255.0 You can use the arp command on a network connected PC/workstation to assign it an alternate IP address.
To do this from a Windows PC:
- Click Start -> Run
- Type cmd and click OK to bring up the command line
- Type arp –d to flush the ARP cache
- Type arp –a to view the current ARP cache which should be empty
Now add a static entry to the ARP table and ping the console server to have it take up the IP address. In the example below we have an SD/CM4000 unit with a MAC Address 00:13:C6:00:02:0F (designated on the label on the bottom of the unit) and we are setting its new IP address to 192.168.100.23. Also the PC/workstation issuing the arp command must be on the same network segment as the console server (i.e. have an IP address of 192.168.100.xxx).
- Type arp -s 192.168.100.23 00-13-C6-00-02-0F (Note for UNIX the syntax is: arp -s 192.168.100.23 00:13:C6:00:02:0F)
- Type ping -t 192.18.100.23 to start a continuous ping to the new IP Address.
- Turn on the console server and wait for it to configure itself with the new IP address. The Opengear will start replying to the ping at this point
- Type arp –d to flush the ARP cache again
