how to configure port to connect switch SG300 to 3com switch

[rdrisaldi]

Hello,

I need help. I have my network with severals SG300 switches.

I have one of them like my core switch working in layer 3 mode. With 2 vlans and vlan interfaces to each vlan.

Everything is working ok.

But now i have to connect one 3com unmanage switch that have host from vlan 1 and 2. How should i connect this switch to my Cisco sg300 switch? What mode should i use in that port?

thanks a lot.

Hello Ruy,

I can not speak for 3com switches, but normally with unmanaged switches there is no way to set vlans.

Use MAC-based VLANs on SG300 L2 switch, register all clients in needed VLANs (or better setup SG300 L2 port to 3com in PVID VLAN with maximum clients and others in MAC-based VLANs).
