Cisco 2950 Switch -----> fas/01 is uplink and fast03/ - 24 ports are connected to ------> 48 port DSLAM (means each port  connected with one 48 port DSLAM) per DSLAM 48 users that means in cisco 2950 per port  48 users connected through DSLAM------> ADSL modem in CPE.

i need maximum security in per port so how can i configure as per my required in cisco 2950 switch.maximum security

There are same VLAN (2) all ports, cause port 1 as a uplink from Billing Authenticaion server all users needs to authenticate through fast0/1 VLAN 2.

You want a port to allow 48 users?  DO NOT configure port security then. DO NOT configre spanning-tree portfast.

If you really want to, try this:

switchport port-security
switchport port-security maximum 48
switchport port-security aging time 2
switchport port-security violation restrict
switchport port-security aging type inactivity
storm-control broadcast level 5.00
storm-control multicast level 5.00
no spanning-tree portfast
