I configured DHCP reserved addresses on the VPN Router YAMAHA RTX1210, so I’ll introduce the method.

Background

The EPSON printer PX-M840FX used in our office checks ink levels from Windows applications, and since that application connects by specifying IP addresses, we needed to fix the IP address.

DHCP Reserved Address Configuration Procedure

I executed commands to the YAMAHA router from http://your-local-ip-address/management/maintenance/command.html.

First, check the DHCP status.

# show status dhcp summary 1
DHCPスコープ番号: 1
  1: (省略)
  ︙
 18:       172.16.0.29:  ac:18:26:2f:eb:xx, EPSON2FEBE0

Since .2 was available, I configured the DHCP reserved address.

# dhcp scope bind 1 172.16.0.2 ac:18:26:2f:eb:xx

Other Useful Commands

To remove the above configuration, you can use the following command:

# no dhcp scope bind 1 172.16.0.2

Manual deletion of DHCP lease information can be done with the following command:

# dhcp manual release 172.16.0.29

That’s all from the Gemba where I made DHCP reserved address configuration changes on a YAMAHA RTX1210 router.
