Chapter 3: Switch Management 39
Enabling the DHCP
or BootP client for
in-band
management
Although it is recommended that you manage the switch by using the remote
management port, you can manage the switch over the production network
through any of the SFP+ switch ports. The procedures in this section describe
how to configure the in-band management interface. For information about
similar procedures to allow out-of-band management, see
“Viewing and
configuring remote management port information” on page 36.
Before you can connect to the switch by using Telnet, SSH, or SNMP, the switch
must obtain an IP address, subnet mask, and default gateway.
To configure the switch to obtain network information from a DHCP or BOOTP
server on the network, follow these steps:
1. Access the switch CLI by using the console port and enter Privileged EXEC
mode as described in
“Connecting to the CLI by using the console port” on
page 35.
2. Enable the DHCP or BOOTP client on the switch:
v To enable DHCP, enter the following command from Privileged EXEC
mode:
network protocol dhcp
If the command is not available, make sure you are in Privileged EXEC
mode. In Privileged EXEC mode, the switch hostname is in parentheses
followed by a pound symbol, for example (
switch)#
.
v To enable BootP, enter the following command from Privileged EXEC
mode:
network protocol bootp
3. Optionally, to enable the DHCPv6 client on the switch, enter the following
command:
network ipv6 address dhcp
4. Enter the
show network
command to view the network information assigned
to the switch by the network server:
(CN1610) #show network
