Displaying accounting information for rate limit usage
To display accounting information for rate limit usage, enter the following command.
Brocade# show rate-limit counters
Syntax: show rate-limit counters [interface slot/port]
The interface slot/port option allows you to get accounting information for a specified interface
only.
Output such as the following will display.
This display shows the following information.
Monitoring rate limit usage by SNMP
Accounting information for rate limit usage can also be monitored by SNMP. The agAclAccntTable
supports the following objects, which map to the rate limit usage counters.
agAclAccntRaclDropCnt: drop counters
agAclAccntRaclFwdCnt: fwd counters
agAclAccntRaclRemarkCnt: re-mark counters
agAclAccntRaclTotalCnt: total counters
For detailed information, please refer to the “Filtering Traffic” chapter of the Unified IP MIB
Reference.
Among other applications, this accounting feature allows per-port VLAN statistics in the inbound or
outbound direction to be extracted by means of SNMP. This can be achieved by adding ACL filters
for the monitored VLAN on the appropriate port. This accounting feature works for all modules of
the Brocade NetIron XMR and Brocade MLX series platforms. For modules that do not support
extended VLAN statistics, this feature provides a means of extracting per-port VLAN statistics.
TABLE 8 Rate limit counters parameters
This field... Displays...
Interface The interface that rate limit accounting information is being displayed for.
rate-limit input A rate limit configuration that defines rate limit policy for inbound traffic on the
defined interface.
Fwd The traffic in bytes that has been forwarded from this interface as a result of
this rate limit policy since the device was started up or the counter has been
reset.
Drop The traffic in bytes that has been dropped from this interface as a result of the
defined rate limit policy since the device was started up or the counter has
been reset.
Re-mark The number of packets whose priority have been remarked as a result of
exceeding the bandwidth available in the CIR bucket for this rate limit policy.
Total The total traffic in bytes that has been carried on this interface for the defined
rate limit policy since the device was started up or the counter has been reset.
