I have a couple of SF300-24P 24-Port 10/100 PoE Managed Switches in my Network. The problem I have is that, even though I name it appropriately at System Settings via the web interface, I dont see the same name when I do a 'Show cdp neigh' from a neighboring switch. Below is a snapshot of what I see.

Hi Sulerazak, I think it depends on your software version running on these switch as well. The system name TLV if I remember correctly was not a default feature in earlier releases.
If you check the setting on the switch for the CDP properties, confirm there is a System name TLV. If it is not there then the host name will be what it is, which I am guessing that looks like some sort of unique product identifier for the switch platform.
On the newer releases of software there is System Name TLV available as a configurable feature along with the CDP version type.

Hello
short answer: perform this command "cdp device-id format hostname" on SG300 switches to get them advertised hostname instead of system MAC address in CDP packets.

Hello,
You can change system device-id display from MAC address (default) to host name or serial number.

I've just confirmed and it appears the firmware is the problem. Perhaps, I need to do an upgrade.Below is a snapshot of the current firmware
