Setting the PLP on T320 and M320 Platforms

By default, the least significant bit of the CoS value sets the packet loss priority (PLP) value. For example, CoS value 000 is associated with PLP low, and CoS value 001 is associated with PLP high. In general, you can change the PLP by configuring a BA or MF classifier, as discussed in Classifier Types.

However, on T-series, MX-series, and M320 platforms that do not have tricolor marking enabled, the loss priority can be configured only by setting the PLP within an MF classifier. This setting can then be used by the appropriate drop profile map and rewrite rule.

For T-series and M320 platforms with Enhanced II Flexible PIC Concentrators (FPCs) and tricolor marking enabled, you can set the PLP with a BA or MF classifier, as described in Setting the PLP with a BA Classifier and Setting the PLP with a Multifield Classifier.
