Monitoring The System - Cisco CE 2000 Platform SCE 2000 4xGBE Installation And Configuration Manual

Chapter 6 Cabling the Line Ports and Completing the Installation
Sniffing: allows the SCE 2000 platform to forward traffic on the specified link through the
•
bypass mechanism while still analyzing the traffic passively.
Sniffing is permitted to be configured for for all links, only (use the all-links option).
Cutoff: completely cuts off flow of traffic through the specified link.
•
Note the following recommendations and restrictions:
Since the SCE 1000 platform has only one link, the link is not specified.
•
Since the SCE 2000 platforms have more than one link, it is required to specify the link. The
•
link designations are different for the GBE and FE platforms, as follows:
Use the 'all-links' option to configure the link mode for all links (SCE 2000 platforms
•
only).
It is recommended that both links be configured together. Use the all-links option.
•
Link mode is relevant only to inline topologies.
•
It is recommended that in cascaded topologies, both SCE 2000 platforms be configured for
•
the same link mode, otherwise the service will be unpredictable.
• Sniffing can only be configured for all links, therefore, to configure sniffing, the all-links
option is required, not just recommended.
The default link mode is forwarding. When other link modes are selected, active service
•
control is not available and any service control configuration will not be applicable.
To set the link mode:
