The inter-card link state adjustment function is designed to improve the
adaptability of the inter-card links in a Switch 7750. It enables you to set the mode
in which inter-card links are established as needed.
n
An inter-card link refers to the internal links between the Fabric and all the service
modules of an Ethernet switch.
Inter-card links can be established in one of the following two modes:
Auto-negotiation mode, where inter-card links are established through
■
negotiation to improve the adaptability and stability. This mode is based on the
corresponding Ethernet standards. By default, the Fabric and the service
modules in a Switch 7750 Ethernet switch negotiate to establish 1000 Mbps
links in between.
Fix mode, where 1000 Mbps links are established between the Fabric and the
■
service modules without negotiation. Therefore, the time for negotiation is
saved. For the switches operating as network nodes, establishing inter-card
links in this mode improves the response speed and reduces the influence on
access devices when module switchovers occur.
n
Since the two modes have no affect on the performance, it is unnecessary to
modify the existing configuration when you employ this function.
