The Insight Interface port is provided as a pre-existing port-channel interface to which all the Insight Interfaces are automatically added during system boot.
The port-channel interface is created as default LAGs in the system. It is visible to you, configured with default settings, and is a static LAG. All other options on the LAG are disabled. Insight Interface ports and port-channels work independently with each providing up to 20 GB bandwidth for applications.
On the SLX 9540, port 0/48 is multiplexed for normal use and as access to the Insight Interface. On the SLX 9640, port 0/24 is used.
When Insight is invoked, the hardware switch reconfigures port 0/48 (or 0/24 on the SLX 9640) to ethernet interface 0/125 and is used exclusively for Insight configuration/management. The user never has to specifically configure Eth 0/125. When a show command is run, no configuration is displayed for port 0/48 (or 0/24 on the SLX 9640).
Insight Interface port-channel creation, addition, or deletion is similar to the standard port-channel creation, addition, or deletion except it is programmatically invoked during system initialization.
