Hello everyone,
I am installing a FTD (5516-X)with FMC for a PoC to my customer.
I have configured a dhcp server on my inside interface.
My 5516-X is linked with a switch in this interface, configured in access mode, vlan 2.
I disabled dhcp snooping for my test.
When I configure : interface vlan 2 => ip add dhcp the switch gets its IP and it is stable :
DHCPD: assigned IP address 10.0.0.109 to client 0063.6973.636f.2d66.3837.622e.32 30.3064.2e35.3763.312d.566c.32.
When I plug my laptop, I have this :
dhcpd_create_automatic_binding() adding NP rule for client 10.0.0.106
DHCPD: assigned IP address 10.0.0.106 to client 0134.e6d7.4cef.30.
DHCPD/RA: Delete binding 10.0.0.106 from radix tree.
DHCPD: returned 10.0.0.106 to address pool inside.
dhcpd_create_automatic_binding() adding NP rule for client 10.0.0.107
DHCPD: assigned IP address 10.0.0.107 to client 0134.e6d7.4cef.30.
DHCPD/RA: Delete binding 10.0.0.107 from radix tree.
DHCPD: returned 10.0.0.107 to address pool inside.
dhcpd_create_automatic_binding() adding NP rule for client 10.0.0.108
DHCPD: assigned IP address 10.0.0.108 to client 0134.e6d7.4cef.30.
DHCPD/RA: Delete binding 10.0.0.108 from radix tree.
DHCPD: returned 10.0.0.108 to address pool inside.
Does someone has any idea of what is going on ?
Thanks for your help !
