Configuring IP parameters – Layer 3 Switches
• When DHCP is disabled, and then re-enabled, or if the system is rebooted, the TFTP process
requires approximately three minutes to run in the background before file images can be
downloaded manually.
• Once a port is assigned a leased IP address, it is bound by the terms of the lease regardless of
the link state of the port.
