Note:
An inter-card link refers to the internal links between the SRPU 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 SRPU and the service cards in an S7500
series Ethernet switch negotiate to establish 1000 Mbps links in between.
Fix mode, where 1000 Mbps links are established between the SRPU 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.
Note:
Since the two modes have no affect on the performance, it is unnecessary to modify the
existing configuration when you employ this function.

1.3 Configuring Internal Channel Monitoring

1.3.1 Introduction

An internal channel refers to the interface channel between the SRPU and the service
cards. The SRPU sends handshake packets to each service card every second. After
receiving the handshake packets, the service cards report the result to the SRPU. In
