Configuring a Source Rate Limit for Each SPAN Session
Purpose
Enters the monitor configuration mode and specifies the SPAN
session for which the source rate limit is to be configured.
Configures the source rate limit for SPAN packets in the specified
SPAN session in automatic or manual:
• Auto mode—Automatically calculates the rate limit on a
per-gigabyte basis as follows: destination bandwidth /
aggregate source bandwidth. For example, if the rate limit
per gigabyte is 0.5, for every 1G of source traffic, only 0.5G
of packets are spanned.
For ingress traffic, the per-gigabyte limit is applied to each
forwarding engine of the F Series module based on how
many ports are used as the SPAN source so that the source
can be spanned at the maximum available bandwidth. For
egress traffic, the per-gigabyte limit is applied to each
forwarding engine of the F Series module without
considering how many ports are used as the SPAN source.
• Manual mode—Specifies the percentage of the maximum
rate of SPAN packets that can be sent out from each
forwarding engine on a module. The range is from 1 to 100.
For example, if the rate limit is 10 percent, the maximum
rate of SPAN packets that can be sent out from each of the
forwarding engines on an F Series module is 1G (or 10
percent of the 10G line rate).
(Optional) Displays the status of SPAN sessions, including the
configuration status of the rate limit, the percentage of the
maximum SPAN rate allowed per session, and the modules on
which the rate limit is and is not supported.
(Optional)
Copies the running configuration to the startup configuration.
