• Enterprise Policy Manager (EPM) release 4.2

provisioning application. You can use EPM to provision filters on the Nortel
SNA network access devices. EPM 4.2 supports preconfiguration of Red,
Yellow, and Green VLAN filters prior to enabling the NSNA feature. In future
releases of the Nortel SNAS 4050 and EPM software, users will have the
additional ability to add and modify security and quality of service filters
while Nortel SNA is enabled on the device.
For general information about installing and using EPM, see Installing Nortel
Enterprise Policy Manager (318389).
