Operation Manual – Hardware-Dependent Software ConfigurationH3C S7500 Series Ethernet SwitchesChapter 1 Hardware-DependentSoftware Configuration1-3Note:An inter-card link refers to the internal links between the SRPU and all the service cardsof an Ethernet switch.Inter-card links can be established in one of the following two modes:z Auto-negotiation mode, where inter-card links are established through negotiationto improve the adaptability and stability. This mode is based on the correspondingEthernet standards. By default, the SRPU and the service cards in an S7500series Ethernet switch negotiate to establish 1000 Mbps links in between.z Fix mode, where 1000 Mbps links are established between the SRPU and theservice cards without negotiation. Therefore, the time for negotiation is saved. Forthe switches operating as network nodes, establishing inter-card links in this modeimproves the response speed and reduces the influence on access devices whenboard switchovers occur.Note:Since the two modes have no affect on the performance, it is unnecessary to modify theexisting configuration when you employ this function.1.2.2 Inter-Card Link State Adjustment ConfigurationFollow these steps to configure inter-card link state adjustment:To do...

The SRPU sends handshake packets to each service card every second. Afterreceiving the handshake packets, the service cards report the result to the SRPU. In |
