  • 1.  dhcp server on segment

    Posted Nov 17, 2021 02:06 PM

    hello

    I had configured a dhcp server on one segment.

    is it a way to see the allocated ip address?

    regards

    Go to the cli of one of your edge nodes and run the following command:

    get dhcp leases all

    This will give you all allocated IP addresses

    In case you're interested in a specific subnet (10.7.12.0 in this example), you can do it like this:

    ssh admin@edge-01 get dhcp leases all | grep -B 9 'SUBNET: 10.7.12.0'

    You will see output in the following format:

    ....

    In case you want to run commands on an edge node automatically, you can set your ssh public key like this:

    set user admin ssh-keys label mylabel type ssh-rsa value AAAAB3NzaC1yc.......
