Configuring IP parameters – Layer 3 Switches
Configuring the TFTP server
The tftp-server command specifies the address or name of the TFTP server to be used by the DHCP
clients.
To configure a TFTP server by specifying its IP address, enter a command similar to the following.
Brocade(config-dhcp-cabo)# tftp-server 101.7.5.48
To configure a TFTP server by specifying its server name, enter a command similar to the following.
Brocade(config-dhcp-cabo)# tftp-server tftp.domain.com
Syntax: tftp-server <address> | name <server-name>
• <address> is the IP address of the TFTP server.
• name configures the TFTP server specified by <server-name>.
If DHCP options 66 (TFTP server name) and 150 (TFTP server IP address) are both configured, the
DHCP client ignores option 150 and tries to resolve the TFTP server name (option 66) using DNS.
Configuring a vendor type and configuration value for a DHCP client
The vendor-class command specifies the vendor-type and configuration value for a DHCP client.
Brocade(config-dhcp-cabo)# vendor class ascii waikiki
Syntax: vendor-class <[<ascii> | <ip> | <hex> ]> <value>
Displaying DHCP Server information
The following DHCP show commands can be entered from any level of the CLI.
Displaying active lease entries
The show ip dhcp-server binding command displays a specific active lease, or all active leases, as
shown in the following example:
Brocade# show ip dhcp-server binding
The following output is displayed:
Brocade# show ip dhcp-server binding
Bindings from all pools:
