[idmcltd001]

I have created 1 VLAN at Cisco SG 3850 at fiber port g1/1/1 with IP range 192.168.1.0/25 and attached one network switch other end on user dept SG 300. all users IP address will be on same range of vlan. now same dept. having requirements to install cctv camera. I want to segregate the traffic

of data and camera. pls guide there is only 1 physical link between L3 and l2

Hi,

You will need to create another Vlan on the 3850 along with  layer 3
SVI with a new subnet.
And on the 300 too you need to add the vlan

Say vlan 44

Then build the inter switch link as a trunk at both ends
to allow both vlans 40 & 44

Allocate some ports for cameras in the 300 and assign them to vlan 44.
Assign allother user ports to vlan 40

Hope this helps

Dear Sir,

but i will require 2 physical link from 3850 to sg 300?

sg 300 is also connected with non manageable e dlink switch so the existing network stop working?

Hi,

Rebuilding the existing link between the 3850 and the 300 you only take a few seconds provided you plan the steps and prepare you config changes properly.

So 2nd link between the switches is not required

Please find the config manual on the CCO site for your version of software for the 300.

(I don't have any experience working on them but I think its from a browser page etc)
