Configure the subtending multicast service.

In the MSTP ring network, MA5600-1 is subtended with Huawei MA5600, and MA5600-3 is subtended with MA5600-4. According to the data plan, MA5600-4 provides the multicast service. In this manner, it is necessary to configure the multicast subtending on MA5600-1 first.

Add the upstream port.

The upstream port is already added in 11.c. It is unnecessary to configure it again.

Configure the IGMP proxy.

The IGMP proxy is already configured in 11.c. It is unnecessary to configure it again.

Configure the program library.

The program library is already configured in 11.c. It is unnecessary to configure it again.

Configuring the GE/FE Optical/Electrical Interface

Generally, the Huawei ME60    sets an Ethernet interface to an optical or electrical interface based on the interface module's type. If the ME60 cannot identify an interface module, you need to manually set the interface to the optical or electrical mode.

Run:

system-view

The system view is displayed.

Run:

interface { ethernet | gigabitethernet } interface-number

The Ethernet interface view is displayed.

Run:

port-type { copper | fiber-100 | fiber-1000 }

The interface type is set.

NOTE:

When an SFP module is being replaced, the configurations such as the loopback test, interface speed, auto-negotiation mode, and duplex mode on the interface are all restored to default ones. You need to reconfigure them on the interface.

After the port-type command is run, the configurations such as the loopback test, interface speed, auto-negotiation mode, and duplex mode on the interface are all restored to default ones. You need to reconfigure them on the interface.

The parameter copper can be configured in the port-type command only when an optical/electrical SFP module is installed.

The CloudEngine 12800 series switch is the next generation data center switches the highest industry performance, the maximum support 48Tbps exchange capacity, three times in the industry level; support each slot 2Tbps bandwidth (can upgrade to 4Tbps), four times the industry level. The CloudEngine 12800 series and CloudEngine 5800/6800 series of core switch cabinet top type switches support high densities of 100GE, 40GE, 10GE and GE interface, and full support of virtual network computing, storage, network support, the fusion of characteristics, which can meet the 4 generation server development for the next 10 years demand for network, help customers to build long-term stable the data center network infrastructure.

Not only that, Huawei will also in the GITEX such a platform to display the comprehensive strength Huawei enterprise network products, including the S9700 T bit core routing switch, with 21us industry minimum inter frame delay of the industry's first enterprise level 802.11ac standard with WLAN AP prototype, leading the industry 2 times the performance of AR G3 enterprise routers, NE series of high-end service router NE40E and facing the global launch of the enterprises in the end router NE20E-S, while in transport and access network advantage products, including support for a maximum of 5 site and multi direction convergence of data transmission of microwave products RTN950, OTN technology will be extended to the access layer of the Mini OTN system OSN 1800, have group properties Hybrid MSTP OSN 550, more than 11 years of commercial experience in xPON solution SmartAX MA5616.

The afternoon of October 17th, Huawei will participate in the forum organizers held a cloud. The customer will share the recent deployment of virtual desktop cloud solution on how to change the operation of the United Arab Emirates university. Huawei  NE40E-X8  also and participants will discuss cloud computing brings to industry changes, and how to play a role in reducing energy consumption.

S2300 Loopback-detect

I am having problems with the function of loopback-detect.it does not work in this case:

If an interface has been added to LS-S2309TP-EI-AC   VLANs in untagged mode, the interface sends one copy of untagged detection packet regardless of how many VLANs the interface has been added to. The untagged detection packets will be discarded on the link, so loopback detection cannot be performed on the network. In this situation, loopback detection must be configured in these VLANs.

If an interface has been added to VLANs in tagged mode, loopback detection must be enabled in specified VLANs, and the interface sends the loopback detection packets of the VLAN that contains the interface and has loopback detection enabled.

After VLAN IDs are specified, the interface sends one copy of untagged loopback detection packets and multiple copies of tagged loopback detection packets with the specified VLAN tags.
