Command
History
Version 9.0(1.3) Introduced on the S5000.
Usage
Information
The order option is relevant in the context of the Policy QoS feature only. For
more information, refer to the “Quality of Service” chapter of the
Dell Networking
OS Configuration Guide.
When you use the log option, the CP processor logs details about the packets that
match. Depending on how many packets match the log entry and at what rate, the
CP may become busy as it has to log these packets’ details.
The monitor option is relevant in the context of flow-based monitoring only. For
more information, refer to
Port Monitoring.
The S5000 cannot count both packets and bytes; when you enter the count byte
options, only bytes are incremented.
NOTE: When ACL logging and byte counters are configured simultaneously,
byte counters may display an incorrect value. Configure packet counters with
logging instead.
