Dynamic DHCP options configuration processing
The system can differentiate between manually configured DHCP options and DHCP options
that were obtained dynamically from the server. Manually configured DHCP options are
retained even when the dynamic IP address is released.
To help identify them, the keyword dynamic is appended to output for all dynamic DHCP options that are reflected in the running configuration.
Note: Only the IP address and the default gateway/default route are persistent across reloads
(after the
write memory is executed to save the configuration). The remaining DHCP options that are obtained
from the DHCP server are relearned when the ICX device reboots.
It is not possible to manually configure the dynamic option. If you attempt to configure a dynamic option manually, an error is displayed stating “Manual configuration is not allowed for this option."
Note: If a static IP Address is configured manually for the device after obtaining a dynamic
IP Address and DHCP options from the DHCP server, all DHCP options are released along
with the dynamic IP Address.
