See Release Notes for the Nortel Secure Network Access Solution, 
Software Release 1.0 (320850-A) for the minimum firmware versions 
required for the IP Phones operating with different call servers.

Each NSNA-enabled port on a network access device can support one PC 
(untagged traffic) and one IP Phone (tagged traffic). Softphone traffic is 
considered to be the same as PC traffic (untagged).

The Nortel SNAS 4050 helps protect the network by ensuring endpoint 
compliance for devices that connect to the network.

Before allowing a device to have full network access, the Nortel SNAS 4050 
checks user credentials and host integrity against predefined corporate policy 
criteria. Through tight integration with network access devices, the Nortel 
SNAS 4050 can: 

•

dynamically move the user into a quarantine VLAN

•

dynamically grant the user full or limited network access

•

dynamically apply per port firewall rules that apply to a device’s connection

Once a device has been granted network access, the Nortel SNAS 4050 
continually monitors the health status of the device to ensure continued 
compliance. If a device falls out of compliance, the Nortel SNAS 4050 can 
dynamically move the device into a quarantine or remediation VLAN.

Note: Where there is both an IP Phone and a PC, the PC must be 
connected through the 3-port switch on the IP Phone.
