Configuring Policy for the Edge Student Fixed Switch

Configuring the Policy Role

The student role is configured with:
  • A profile-index value of 2
  • A name of student
  • A port VLAN of 10
  • A CoS of 8

Create a policy role that applies a CoS 8 to data VLAN 10 and configures it to rate-limit traffic to 1M with a moderate priority of 5.

StudentFS->configure policy profile 2 name student pvid-status 
enable pvid 10 cos-status enable cos 8

Assigning Hybrid Authentication

Configure the RADIUS server user accounts with the appropriate tunnel information using VLAN authorization and policy filter-ID for student role members and devices. Enable hybrid authentication, allowing the switch to use both the filter-ID and tunnel attributes in the RADIUS response message. Set a VLAN-to-policy mapping as backup incase the response does not include the RADIUS filter-ID attribute. This mapping is ignored in case RADIUS filter-ID attribute is present in the RADIUS response message.

StudentFS->configure policy maptable 10 2

Assigning Traffic Classification Rules

Forward traffic on UDP source port for IP address request (68), and UDP destination ports for protocols DHCP (67) and DNS (53). Drop traffic on UDP source ports for protocols DHCP (67) and DNS (53). Drop traffic for protocols SNMP (161), SSH (22), Telnet (23) and FTP (20 and 21) on both the data and phone VLANs.

Students should only be allowed access to the services server (subnet 10.10.50.0/24) and should be denied access to both the administrative (subnet 10.10.60.0/24) and faculty servers (subnet 10.10.70.0/24).
