• NetBIOS Node Type (Option 46)—Select how to resolve the NetBIOS name. Valid
node types are:
- Hybrid—A hybrid combination of b-node and p-node is used. When configured to
use h-node, a computer always tries p-node first and uses b-node only if p-node
fails. This is the default.
- Mixed—A combination of b-node and p-node communications is used to register
and resolve NetBIOS names. M-node first uses b-node; then, if necessary, p-node.
M-node is typically not the best choice for larger networks because its preference
for b-node Broadcasts increases network traffic.
- Peer-to-Peer—Point-to-point communications with a NetBIOS name server are
used to register and resolve computer names to IP addresses.
- Broadcast—IP Broadcast messages are used to register and resolve NetBIOS names
to IP addresses.
• SNTP Server IP Address (Option 4)— Select one of the device's SNTP servers (if
already configured) or select Other and enter the IP address of the time server for the
DHCP client.
• File Server IP Address (siaddr)—Enter the IP address of the TFTP/SCP server from
which the configuration file is downloaded.
• File Server Host Name (sname/Option 66)—Enter the name of the TFTP/SCP server.
• Configuration File Name (file/Option 67)—Enter the name of the file that is used as
a configuration file.
Click Apply. The Running Configuration file is updated.
DHCP Options
When the device is acting as a DHCP server, the DHCP options can be configured using the
HEX option. A description of these options can be found in RFC2131.
The configuration of these options determines the reply that is sent to DHCP clients whose
packets include a request (using option 55) for the configured DHCP options.
Example: The DHCP option 66 is configured with the name of a TFTP server in the DHCP
Options page. When a client DHCP packet is received containing option 66, the TFTP server
is returned as the value of option 66.
