Operation Manual – Hardware-Dependent Software ConfigurationH3C S7500 Series Ethernet SwitchesChapter 1 Hardware-DependentSoftware Configuration1-4this case, the SRPU knows that the service cards are operating normally. Through thisprocess, the SRPU can judge whether each service card in the device operatesnormally.S7500 Ethernet switches support this feature. Through this feature, you can monitorinternal channels.You can also set the maximum number of times the SRPU fails to receive handshakepackets. If the number of times the SRPU fails to receive handshake packets exceedsthe upper limit, the switch resets the processing chip automatically. When the SRPUreceives handshake packets, it resets the counter automatically.You can also set whether to restart the service card or the switch when the number oftimes the SRPU fails to receive handshake packets exceeds the upper limit.1.3.2 Monitoring Internal Channel ConfigurationFollow these steps to monitor internal channels:To do...
