CoS Capabilities and Limitations on IQ2 and IQ2E PICs (M Series and T Series Platforms)
This topic describes CoS scaling and performance parameters that apply to IQ2 and IQ2E PICs on M series and T series routers.
Rewrite Operations
802.1p or 802.1ad rewrite operations are done on the PIC. A total of eight rewrite markers of each type are supported on the PIC. For other rewrite operations, the numbers are the same as for any other M series FPCs. See CoS Features and Limitations on J, M, and T Series Routersfor details.
Classification
Classification is done on the PIC. There are eight classifier tables of each type (ieee-802.1p, mpls-exp, inet-precedence, dscp, and dscp-ipv6) supported per PIC.
For each classifier type, one table is reserved for a default classifier. This table is used when no classifier is configured, or when the number of tables configured exceeds eight.
