Locating connected upstream switch

[DIGGERPNS]

Hi everyone,

I have inherited a custome with a bunch of SG300's in their LAN room and one out in the warehouse.

I need to setup a VLAN and the genius before me did not label which LAN room switch the warehouse unit plugs into. Is there a tool/method I can use to find which switch, and port this warehouse switch is connected to?

Thanks in advance.

Hi David, if the switch is on a relatively new firmware (anything but 1.0.0.27) then you can use CDP to find the directly connected switches.

If theyre on the original firmware, you'll have to use mac address table.

Thanks Tom, a colleague actually told me about this function yesterday as well.

Appreciate the feedback.
