Status changes on interfaces within the configured delay. You can configure the delay in reporting physical statusĬhanges to solve the problem. Status changes are reported to the system, extra system costs are The upper-layer service forwarding protocol to send service packets Protection group changes from Up to Down, the system immediately instructs ForĮxample, when the physical status of the active interface in an interface The systemĪlso automatically generates traps and logs to remind users to performĬorresponding operations on physical links. Of the change to direct packet receiving and forwarding. Upper-layer protocol modules (such as the routing and forwarding modules) When the physical status changes, the system notifies The physical status of an Ethernet interfaceĬan be Up or Down. Run the negotiation auto command to configure the Ethernet interface to work in auto-negotiation mode. In this case, you can run the auto speed 100 100 command toĬonfigure the auto-negotiation speed to 100 Mbit/s for GE1/0/1, GE1/0/2, and GE1/0/3, preventing the outbound interface from being blocked. When the servers send data at the speed of 1000 Mbit/s concurrently, the outbound interface GE1/0/4 will be blocked. If the auto-negotiation speed is not specified on the device, the speeds negotiated by GE1/0/1, GE1/0/2, and GE1/0/3 with their connected serversĪre all 1000 Mbit/s. The servers connect to GE1/0/1, GE1/0/2, and GE1/0/3 respectively.
To external networks is also 1000 Mbit/s. If the negotiated rate is not the required one, run the auto speed command to set the auto-negotiationįor example, the network adapter speeds on Server1, Server2, and Server3 that form a server cluster are all 1000 Mbit/s, and the speed of the outbound interface GE1/0/4 connecting the device In auto-negotiation mode, interfaces on both ends of a link negotiate their rate. The interfaces on both ends of a link must have the same duplexĭo not support the duplex mode configuration. Mode configuration when they are equipped with GE copper modules. The GE optical interfaces support the duplex If theĭuplex mode is changed to half-duplex, the GE electrical interface In auto-negotiation mode, a GE electrical interface that worksĪt a rate of 1000 Mbit/s only supports the full-duplex mode. Interface to work in auto-negotiation mode.Īn FE electrical interface negotiates the duplex mode with the peer Run the negotiation auto command to configure Ethernet After the auto-negotiation succeeds, the interfaces work in half-duplex mode. You can run the auto duplex half command to set the duplex mode to half-duplex. If service traffic volume of enterprise users is low, interfaces at both ends of a link can meet data transmission requirements when they work in half-duplex mode.After the auto-negotiation succeeds, the interfaces work in full-duplex mode.

You can run the auto duplex full command to set the duplex mode to full-duplex. If service traffic volume of enterprise users is high, interfaces at both ends of a link must work in full-duplex mode.The negotiated duplex mode is not the required one, you can run the auto duplex command to set the required duplex mode in Interfaces on both ends of a link negotiate their duplex mode. In addition, an Eth-Trunk cannot be unidirectionally isolated from However, an interface cannotīe unidirectionally isolated from itself or from the management interface. Unidirectionally, run the port-isolate mode all command. To isolate both Layer 2 and Layer 3 packets on interfaces Interface are isolated from a specified interface, but Layer 3 packetsĪre not isolated. Unidirectional isolation between these interfaces.īy default, only Layer 2 packets of the current To isolate interfaces in different port isolation groups, configure Interfaces in a port isolation group are isolated from each other,īut interfaces in different port isolation groups can communicate.Then the other hosts do not receive packets from the host. The interface connected to the host from other interfaces unidirectionally. When multiple hosts connect to different interfaces of a deviceĪnd a host sends many broadcast packets to the other hosts, isolate.Unidirectional isolation needs to be configured Is isolated from interface B unidirectionally, packets sent from interfaceĪ cannot reach interface B, but packets sent from interface B can
