DHCP Disable (Static IP Addressing)
DHCP is disabled in the default configuration. Initially, modules are assigned a Static
default IP Address of 10.10.10.10. Changes to the Static IP Address can be added
manually through iView
2
(iConfig view) or a Console session. The changes will be
initiated following reboot of the module.
DHCP Enable (Dynamic IP Addressing)
If a DHCP server is present on the network and DHCP is enabled, the DHCP client
will initiate a dialogue with the server during the boot up sequence. The server will
then issue an IP address to the management card. Once the new IP address is
received, the SNMP Management Module will reboot so that the new IP address will
take effect. Refer to About Serial Port Configuration for more information about
Enabling/Disabling DHCP.
When there is no DHCP server on the network, use the serial configuration to
manually set the IP addresses.
When DHCP is enabled, the IP address (default 10.10.10.10 or a previously used IP
address, or user-configured) is saved. When DHCP is disabled, the saved IP address
will be reinstated and the device will reboot.
DHCP servers give out lease times: devices renew their leases based on the
administrator-specified time. If a device cannot renew its lease, and the lease expires,
the device will be given the IP address 10.10.10.10 and will reboot.
