PowerConnect 6248 and 2848 configuration
Hello,
First time I am dealing with Networking and would like to ask for your help.
Two weeks of my DIY did not help me alot.
Scenario:
1 6248 Switch (Core Switch)
6 2848 Switches (Desktop Switches - 3 per subnet)
1 2748 Switch (Backup Subnet)
Subnets:
1 - Servers\printers (DC, DHCP, DNS) - DG 10.0.0.100 /24
2 - Backup (For Veritas backup) - DG 10.0.4.100
3 - External (For connection to Back TMG) - DG 10.0.5.100
10 - Desktops 1 - DG 10.0.1.100
20 - Desktops 2 - DG 10.0.2.100
Infrastracture
DC, DNS, DHCP - 10.0.0.2 - 10.0.0.3
Subnet 1(servers\priners) directly attached to 6248 on ports g1-g36
Subnet 10 (Desktops 1) uses g37-g40 (Should I connect 3 2848 switches directly to ports or do a trank?)
Subnet 20 (Desktops 2) uses g41-g44 (Should I connect 3 2848 switches directly to ports or do a trank?)
Subnet 2 g45-g46 (Connects to 2748)
Subnet 3 g47-g48 (Goes directly to TMG server 10.0.5.10)
How do I configure 6248 and 2848 switches to make all of this work.
Please help!

Well the easiest solution is to only have a 1gb "backbone" by not using any trunking. You would configure the 6248 to do the following:
1) Create VLANs for each subnet (I try to use a number similar to the subnet), 2) assign switch an IP in each vlan, 3) set ports to be in vlan, 4) set default gateway
config
vlan database
vlan 100
vlan 101
vlan 102
vlan 103
vlan 104
exit
int vlan 100
description servers-10.0.0.x
ip address 10.0.0.1 255.255.255.0
exit
int vlan 101
description desktops1-10.0.1.x
ip address 10.0.1.1 255.255.255.0
exit
int vlan 102
description desktops2-10.0.2.1 255.255.255.0
ip address 10.0.2.1 255.255.255.0
exit
int vlan 104
description backup-10.0.4.x
ip address 10.0.4.1 255.255.255.0
exit
int vlan 105
description external-10.0.5.x
ip address 10.0.5.1 255.255.255.0
exit
int range ethernet g1-36
switchport access vlan 100
exit
int range ethernet g37-40
switchport access vlan 101
exit
int range ethernet g41-44
switchport access vlan 102
exit
int range ethernet g45-46
switchport access vlan 104
exit
int range ethernet g47-48
switchport access vlan 105
exit
Then you'll need a default route to the internet, but since I don't know where your uplink is going to be I'm going to guess at the IP:
ip route 0.0.0.0 0.0.0.0 10.0.5.254
Set the PC's in each group to use the IP address of the switch as their gateway. Note that the switch is not doing DHCP, so you'll need one in each vlan or hard-code them on each desktop.
Note that "description" might not work there, if it doesn't use "name" instead.

Thank you so much! Everything is up and running. The problem was is that I did not set default gateway...

You should be able to add the following lines to your core switch that will enable dhcp relay to your other switches and nodes.
bootpdhcprelay enable
bootpdhcprelay serverip XXX.XXX.XXX.XXX (DHCP SERVER IP)
