IP Configuration
DHCP Server
STEP 4
Cisco 500 Series Managed Switch Administration Guide
• Domain Name Server IP Address (Option 6)—Select one of the devices DNS
servers (if already configured) or select Other and enter the IP address of
the DNS server available to the DHCP client.
• Domain Name (Option 15)—Enter the domain name for a DHCP client.
• NetBIOS WINS Server IP Address (Option 44)— Enter the NetBIOS WINS
name server available to a DHCP client.
• 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.
Excluded Addresses
By default, the DHCP server assumes that all pool addresses in a pool may be
assigned to clients. A single IP address or a range of IP addresses can be
excluded. The excluded addresses are excluded from all DHCP pools.
