TCP/IP Administration
NOTE: You will need to restart the PT22 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 DCHP boot delay:
The Set DHCP Boot Delay command enables or disables the DHCP boot delay option.
Enabling
the Boot Delay option gives the PT22 approximately 90-seconds to establish a connection
through a DHCP server This interval allows various network component activities to occur as the unit
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 PT22 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
outlets on the unit. 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 DCHP static address fallback:
The Set DHCP Static Address Fallback command enables or disables the DHCP static address fallback
option.
Enabling
the Static Address Fallback option informs the PT22 to automatically fall back to a static
address if a DHCP server does not respond after 90-seconds. This is the default state.
Disabling
the Static Address Fallback option generates periodic DHCP server requests until the unit
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.
NOTES:
 DHCP must be enabled to activate the DHCP Static Address Fallback option.
 If the DHCP server boot time is excessive, you can 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 the Network-Enabled
Modes section of this manual.
At the Switched CDU: prompt, type set net; followed by disabled, ipv4only, or dualv6v4; and press
Enter.
