Urgent help setting up a switch that got reset

Hi Guys,

We have a Cisco SG200-50 at our datacenter and the employee that originally set it up is no longer with us. 

We had a power issue at the datacenter last night that, among other things, seems to have reset the switch to factory defaults. If we have a backup of the configuration, we do not know where it is and can no longer contact the ex-employee.

The switch's configuration was pretty basic I think, and I had better learn how to do this..... so I am here hoping someone can give me a kick in the right direction. 

While this is a 50 port switch, we only use about 10 ports. 

Port 49 is a single VLan drop from our datacenter that contains all of our IPs (multiple subnets) in a single drop, which does not need to be vlan tagged to work - it just works. If it were not for our "other" networks, we would not need to configure this switch at all. 

ports 25-48 should be connected to that Vlan link on 49. This is our "primary" network. As it stands now, this is working on most of our servers, but not all, even with the reset settings.

Ports 1-11 is a 10.5.6.0 LAN

Ports 12-20 is a 10.5.5.0 LAN

Thats it. We just need ports 1-11 isolated, ports 12-20 isolated, and then 21-50 isolated in such a way as so that each of those acts as its own "switch".

Sorry if I do not yet know the terminology for this... but I am brand new to switch operations. 

I have the login for our switch's internal website control panel, but have no idea how to set this up... Can some really nice helpful soul out there give me a kick in the right direction?


Thanks,

Dave

very quick response:

  1. create three VLANs
  2. put each group of ports in one of that VLAN
  3. done

to apply that instructions above, you can use this knowledge base record as step-by-step guide.
