Forwarding — forwards traffic on the specified link to the SCE platform for processing.
Bypass — stops all forwarding of traffic on the specified link to the SCE platform. Traffic still flows
on the link, but is not processed in any way by the SCE platform.
This does not affect the redundancy states.
Sniffing — allows the SCE 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 all links, only (use the all-links option).
Cutoff — completely cuts off flow of traffic through the specified link.
Since the SCE 2000 platforms have more than one link, it is required to specify the link. The link
designations are as follows:
GBE1-GBE2/GBE3-GBE4
–
Use the ' all-links' option to configure the link mode for all links.
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 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.
