1. Establish a DAD environment for the new switch. (Make sure DHCP is enabled on the management
interface.)
a)
The management interface of the switch must be set up as DHCP. After setting up the
management interface on a switch in either standalone mode or fabric cluster mode, you
must use the copy running-config startup-config for the configuration to take effect.
b) The DHCP server must have the FTP server IP address and configuration file path.
c) The configuration file is on FTP server and it contains the firmware path, new configuration
file path, VCS ID, VCS mode, and RBridge ID.
d) The DHCP server and FTP server must be up-and-running.
e) DAD must be enabled on the switch using the CLI.
2. Enable DAD by using the dhcp auto-deployment enable command, and enter yes when prompted
to reboot the system.
During system bootup, the DHCP auto-download process downloads the DAD configuration file and
obtains the VCS mode for a standalone switch, and VCS ID and RBridge ID settings for a switch in
fabric cluster mode. The switch configuration is retrieved from the FTP server if one is set up.
NOTE
The DAD process will abort if any error is detected.
3. If node configuration needs to be downloaded, set up the new configuration as the startup
configuration so it will be applied automatically.
The DHCP auto-download process invokes a firmware download if new firmware is detected. After
the firmware download completes successfully, the switch comes up with the new firmware and
configuration settings.
4. Use the show dadstatus command to view the current DAD configuration.
Telnet and SSH considerations and limitations
• Access to the switch is not allowed for both inbound Telnet and SSH connections from both IPv4
and IPv6 addresses when the Telnet or SSH server are disabled.
• Outgoing Telnet or SSH connections from the switch to any remote device is not affected by
disabling or enabling the Telnet or SSH server in the switch.
• No RASLog or auditlog messages are reported when the Telnet or SSH server is disabled or
enabled.
Ethernet management interfaces
The Ethernet network interface provides management access, including direct access to the Network
OS CLI. You must configure at least one IP address using a serial connection to the CLI before you
can manage the system with other management interfaces. You can either configure static IP
addresses, or you can use a Dynamic Host Configuration Protocol (DHCP) client to acquire IP
addresses automatically. For IPv6 addresses, both static IPv6 and stateless IPv6 autoconfiguration
are supported.
ATTENTION
Setting static IP addresses and using DHCP are mutually exclusive. If DHCP is enabled, remove the
DHCP client before you configure a static IP address.
