NETWORK CONFIGURATION

 

The EX7000 Network Configuration page can be seen in Figure 4-5. By default, the EX7000 will

 

attempt to locate a DHCP server. If one is found, the IP address assigned by the DHCP server will

 

be assumed, along with subnet masks, gateway, etc. Otherwise, after a timeout of 20 seconds, the

 

unit will attempt to obtain an IP address by using AutoIP (IPv4 Dynamic Link Local Addressing).

 

 

 

 

 

NOTE

The EX7000 can be returned to a known, default network configuration by using the LCI (LAN

 

Configuration Initialize) Mechanism. See Reset Button for more information.

 

AutoIP is a mechanism for finding an unused IP address in the IANA assigned range 169.254.X.Y

 

(169.254/16) where X is in the range 1 - 254 and Y is in the range 0 - 255. The device will first

 

attempt to obtain the specific address 169.254.X.Y, where X and Y are the second-to-last and last

 

octets of the device’s MAC address. However, X will be set to 1 if it is 0 in the MAC address, and

 

to 254 if it is 255 in the MAC address for conformance with the AutoIP specifications. If this

 

address is already in use, the unit will attempt to obtain other IP addresses in the 169.254/16 range

 

in a pseudorandom fashion until it finds one that is available.

 

To illustrate the AutoIP mechanism, Table 4-1 lists the AutoIP default address for some example

 

MAC addresses.

TABLE 4-1: AUTOIP DEFAULT ADDRESS ASSIGNMENT

If a static IP address assignment is preferred, one can be optionally assigned via the embedded web page interface. This is done by clicking the Network Configuration link, disabling DHCP and AutoIP, enabling Static, and then assigning a static IP address, subnet mask, and gateway address, and, optionally, up to three DNS servers (see Figure 4-5).
