I have a nortel 3510-24t HW:32 FW:4.0.0.7 SW:v4.0.4.00
I have 128 public ip on an ethernet cable connected to the switch.
I would like to create 4 subnet of 32 ip and assign every subnet to a
specific vlan
I also need to shape the internet band assign to every vlan.
In addition to that I need a configuration that allow me to prevent a
user of vlan b to change its own ip to an ip of vlan a and use the
settings of vlan a.
For a concrete example:

let us assume to have a subnet like 192.168.1.0/25 with 192.168.1.1 as
gateway (i have used private ip instead of the real public subnet only
for example)
I want to create 4 vlan

vlan_a 192.168.1.0/255.255.255.224
vlan_b 192.168.1.33/255.255.255.224
and so on.

on the switch I set vlan_a address to 192.168.1.2, vlan_b address to
192.168.1.34 and so on.

A pc on vlan_a will have an ip like 192.168.1.10 and gateway
192.168.1.2
A pc on vlan_b will have an ip like 192.168.1.35 and gateway
192.168.1.34
etc

how can I configure the switch to do the routing in the right way?
I also need to avoid user to insert 192.168.1.1 as gateway. I want to
force every user to use his vlan address as gateway.
In addition to that I need to do shaping on vlan traffic.

Thanks for the help.

You can use Qos to meet your requirements.
The Qos of ERS3510 can provide ACL, Qos, and Traffic Metering.
