Switch hostname

    Hello.

    On my DHCP server which is on my Firewall I can see the hostnames of IP obtained devices, but for Aruba CX Switch I don't see that. In my Firewall I see only IP and MAC address for Aruba CX.

    Is the switch obtaining an IP address via DHCP or is it static (not communicating with DHCP...)?

    Most probably Aruba CX does not send Option 12 in its DHCP Request message, therefore its hostname is not visible to the DHCP service in your Firewall.
