    The Ethernet Routing Switch 4500 Series can be configured as a network access device for the Nortel SNA solution. Nortel SNA is a protective framework to secure the network completely from endpoint vulnerability. The Nortel SNA solution addresses endpoint security and enforces policy compliance.

The DSCP values that are remapped are associated with a non-zero 802.1p user priority value in the DSCP-to-COS Mapping Table.
  • Page 31 The default for layer 2 non-IP traffic is to pass the traffic through all interfaces classes with the QoS values for 802.1p and drop precedence unchanged. The Nortel Ethernet Routing Switch 4500 Series does not trust the DSCP of IPv4 traffic received from an untrusted port, however, it does trust the DSCP of IPv4 traffic received from a trusted port.

Statistics can also be tracked for QoS. The Nortel Ethernet Routing Switch 4500 Series supports statistics for each policy and for each policy, classifier, or interface statistics tracking.
