Port-car Configuration
Chapter 38. Port-car Configuration
38.1 Port-car Overview
Port-car can protect switch from packet attacking whose destination MAC begins with
01:80:c2. Most of L2 protocol packets (such as BPDU packets of STP) whose destination
MAC begins with 01:80:c2 will send to CPU. After enabling Port-car, the packet rate will be
controlled under the configured threshold.
Table 37-5 summarizes common protocol packets whose destination MAC begins with
01:80:c2.
