TCP/IP Administration
NOTE: A restart of the PDU is required after setting or changing any TCP/IP configurations.
Enabling or disabling DHCP support:
The Set DHCP command enables or disables DHCP support.
To enable or disable DHCP support:
At the Switched CDU: prompt, type set dhcp, followed by enabled or disabled, and press Enter.
Enabling or disabling DHCP boot delay:
The Set DHCP Boot Delay command enables or disables the DHCP boot delay option:
Enabling the Boot Delay option gives the PDU approximately 100-seconds to establish a connection through
a DHCP server
This interval allows various network component activities to occur as the PDU powers up
(such as obtaining SNTP time stamps for logging or allowing SNMP traps to be sent as switched outlets
power up). This is the default state.
Disabling the Boot Delay option forces the PDU to boot after approximately 5-seconds regardless of the
DHCP acquisition state. This speeds up a boot when a DHCP server is connected to one of the PDU’s
outlets. In this configuration, SNMP traps, SNTP and other protocols will not be available until a DHCP
address has been resolved.
To enable the boot delay:
At the Switched CDU: prompt, type set dhcp, followed by bootdelay, followed by enabled or disabled, and press
Enter.
NOTES:
The Boot Delay option executes only when DHCP is enabled.
The firmware can detect network link integrity and will wait for network connection. This means that if the network is not currently
connected, the enabled Boot Delay option will be ignored.
Enabling or disabling DHCP static address fallback:
NOTE: DHCP must be enabled to activate the DHCP Static Address Fallback option.
The Set DHCP Static Address Fallback command enables or disables the DHCP static address fallback option:
Enabling the Static Address Fallback option informs the PDU to automatically fall back to a static address if
a DHCP server does not respond after 100-seconds. This is the default state.
Disabling the Static Address Fallback option generates periodic DHCP server requests until the PDU obtains
a dynamic address.
To enable the static address fallback:
At the Switched CDU: prompt, type set dhcp, followed by staticfallback, followed by enabled or disabled, and
press Enter.
NOTE: If the DHCP server boot time is excessive, you may need to disable the DHCP Static Address Fallback option.
Setting the network acquisition method:
The Set Net command determines the acquisition method used for the protocol stack and IPv4/IPv6 address.
For a detailed description of the Disabled, IPv4 only, and Dualv6v4 options, see
At the Switched CDU prompt: type set net; followed by disabled, ipv4only, or dualv6v4; and press Enter.
