Since a Windows PC will typically fall back to using an Automatic Private IP address
if it fails to find a DHCP server, randomly selecting an address in the 169.254.x.x
range, the unit should become accessible without having to change any settings on
the PC.
Note
: If multiple units are to be accessed via the aux interface from the same PC,
ARP table entries on the PC will need to be cleared when moving between units.
For a Windows PC, open a DOS/CMD window and type the command:
arp
–
d 169.254.42.42
7.2 IP
The unit supports IPv4. It does not support IPv6.
7.3 DHCP
The unit can act as a DHCP client, allowing an IP address to be assigned by an
external server. This can be enabled on a per-management-interface basis, so a
mixture of DHCP and statically-assigned IP addresses is possible.
With DHCP enabled, and with the correct server setup, the unit can learn additional
information, as shown below:
DHCP Option
Value supplied by server
50
IP address
1
Net mask
3
Default gateway
66
TFTP primary server address
4
NTP server address
Table 7.2 DHCP options
Note
: The TFTP and NTP server addresses are global settings. If multiple DHCP
servers supporting these options are accessed by the unit, then the most recent
DHCP activity will be reflected in the unit's settings.
If the TFTP and NTP server addresses are configured manually, these values will
override any obtained via DHCP. To cancel an override, the address 0.0.0.0 should
be entered.
7.4 TCP
The unit supports the TCP protocol in order to provide a number of higher-level
protocols: Telnet, SSH, HTTP, , etc. The unit can maintain a maximum of
16 concurrent TCP connections.
