3COM 3CR17333-91/HP 4210 VLAN questions

3COM 3CR17333-91/HP 4210 VLAN questions

3COM 3CR17333-91/HP 4210 VLAN questions

(OP)
Dear all,

I recently found 3CR17333-91/HP 4210 switch in one of our storage and needed some help setting up (I upgraded to the latest firmware and web).

What I'm trying to do is to separate this switch into 3 different network.
Background:
- 1 Cable modem (internet connected to Router A)
- 3 Router (Call it Router A (IP 192.168.10.1) and B (IP 192.168.20.1) and Router C (IP 192.168.0.1) )
- 1 Switch (3CR17333-91)

What I'm trying to do is to seperate:
Port 1-4 - (Vlan 1) to be used with router A (Call it Group 1)
Port 5-8 - (Vlan 2) to be used with router B (Call it group 2)
Port 9-12 -(Vlan 3) to be used with router C (Call it group 3)

How can i seperate the ports on the switch, so Group 2 and 3 can get internet from group 1 but not able to access each other internal LAN devices.

I tried creating VLAN from the web management, but kept getting message: "Vlan-interface must be the same as Management-vlan"

Can someone help ? and everytime i try to create VLAN (Device --> VLAN), it never saved and yes i did save configuration.

Thank You and i hope i'm i explain it properly.

PS: Can this switch (3CR17333-91) assign DHCP ? so i can eliminate the use of router B and C ??
