If the number of flows for a specific time interval is exceeded, then no packets are logged for this time interval. To protect the system memory, a limited number of flows are collected for each time interval. The logger writes the partial header of the packet (L2 or 元) to the syslog, with a timestamp and some additional information such as ingress interface and the VLAN to which the packet belongs. ACLs can log packets that pass through the switch, so the flows can later be analyzed.Ī packet that hits an ACL with a log clause is passed to the logger. Switch (config interface ethernet 1/1)# exitĪ strong insight into the system is given by ACL logging.
