Configuring Inter-Card
Link State Adjustment
Introduction The inter-card link state adjustment function is designed to improve the
adaptability of the inter-card links in the Switch 7750 Family. 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 Switch Fabric and all the
service cards 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 Switch Fabric and the service
cards in a Switch 7750 Family Ethernet switch negotiate to establish 1000
Mbps links in between.
■ Fix mode, where 1000 Mbps links are established between the Switch Fabric
and the service cards 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 board 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.
