modify the existing configuration file.

For example:
PingAttempts=0
PingDelay=500
HonorRequestedLeaseTime=False
RegisteredClientsOnly=False
ForceClass=None
5 After entering the required information in the dhcpd.pcy file, type :wq to save the changes made to
the dhcpd.pcy file.

Notes.
• If the dhcpd.conf file is corrupted, the dhcpd.conf.lastgood file is used as a backup file.
• If the dhcpd.conf file is updated successfully, then the dhcpd.conf.lastgood file is over written with
the configurations present in the dhcpd.conf file.
• Properly configured dhcpd.conf and dhcpd.pcy files can be transferred to the switch remotely instead
of using the vi editor.
Note. The dhcp-server restart command automatically updates the dhcpd.conf, dhcpd.conf.lastgood and
dhcpd.pcy files.
