Configuring PhoneFS Policy for the Edge Fixed Switch

Configuring the Policy Role

The phoneFS role is configured on both the dorm room and faculty office Fixed Switches with:

Because we can not apply separate rate limits to the phone setup and payload ports on the Fixed Switch using policy rules, apply CoS 10 with the higher payload appropriate rate limit of 100k bps and a high priority of 6 to the phoneFS role.

cos-status enable cos 10

Assigning Traffic Classification Rules

Drop traffic for protocols SNMP (161), SSH (22), Telnet (23) and FTP (20 and 21) on the phone VLAN. Forward traffic on UDP source port for IP address request (68) and forward traffic on UDP destination ports for protocols DHCP (67) and DNS (53) on the phone VLAN, to facilitate phone auto configuration and IP address assignment.

Assigning Hybrid Authentication

Configure the RADIUS server user accounts with the appropriate tunnel information using VLAN authorization and policy filter-ID for phoneFS 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 if RADIUS filter-ID attribute is present in the RADIUS response message.
