The trap rate limiter uses a token bucket scheme, in which traps are sent only if there are
tokens in a virtual bucket. Tokens are added to the bucket every 'token interval,' which sets the
maximum long term trap rate. Each time a trap is sent, the number of tokens in the bucket
decrements. The 'bucket size' is the maximum number of tokens that the bucket can hold. The
bucket size limits the trap burst size.
1. Use the rtp-stat qos-trap-rate-limit command. For example:
G350-001# rtp-stat qos-trap-rate-limit 2000 10
In this example configuration, the token-interval is 2000 and the bucket-size is 10. This
means that a token is added to the bucket every 2000 hundredths of a second
(20 seconds) and the bucket is limited to a maximum size of 10 tokens.
Analyzing RTP statistics output
This section describes the reports, statistics, and traps you can view, how to view them, and
how to understand the output.
Viewing RTP statistics summary reports
RTP statistics summary reports display QoS trap statistics for the VoIP engine(s).
1. Use the show rtp-stat summary command. For example:
G350-001(super)# show rtp-stat summary
Total QoS traps: 23
