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 Conguration Guide.
When you use the log option, the CP processor logs detail 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 ow-based monitoring only. For more information, refer to
the Port Monitoring chapter.
The C-Series and S-Series cannot count both packets and bytes, when you enter the count byte options,
only bytes are incremented.
NOTE: When you congure ACL logging and byte counters simultaneously, byte counters may
display an incorrect value. Congure packet counters with logging instead.
