Chapter 8: Basic IP Routing BMD00136, November 2009
You may add up to five (5) gateways for each static route.
Use the following command to check the status of ECMP static routes:
Dynamic Host Configuration Protocol
Dynamic Host Configuration Protocol (DHCP) is a transport protocol that provides a framework for
automatically assigning IP addresses and configuration information to other IP hosts or clients in a
large TCP/IP network. Without DHCP, the IP address must be entered manually for each network
device. DHCP allows a network administrator to distribute IP addresses from a central point and
automatically send a new IP address when a device is connected to a different place in the network.
The switch accepts gateway configuration parameters if they have not been configured
manually. The switch ignores DHCP gateway parameters if the gateway is configured.
DHCP is an extension of another network IP management protocol, Bootstrap Protocol (BOOTP),
with an additional capability of being able to allocate reusable network addresses and configuration
parameters for client operation.
Built on the client/server model, DHCP allows hosts or clients on an IP network to obtain their
configurations from a DHCP server, thereby reducing network administration. The most significant
configuration the client receives from the server is its required IP address; (other optional
parameters include the “generic” file name to be booted, the address of the default gateway, and so
forth).
Note – DHCP configuration is available only for interface 1.
