How to Perform Ping and Tracert Operations of Huawei S2300/S3300 Series Switch

Configuration Requirements for Performing Ping and Tracert Operations of a Huawei S2300/S3300 Series Switch As shown in the below picture, after configuring SwitchA, check the link between SwitchA and the log host. If the link is disconnected, you need to locate the fault.

Configuration Roadmap for Performing Ping and Tracert Operations of a Huawei S2300/S3300 Series Switch The configuration roadmap is as follows: 1. Run the ping command on SwitchA to check connectivity between SwitchA and the log host. 2. Run the tracert command to locate the faulty link segment if the link is disconnected. Procedure for Performing Ping and Tracert Operations of a Huawei S2300/S3300 Series Switch Step 1 Run the ping command. # Run the ping command on SwitchA to check connectivity between SwitchA and the log host. <Quidway> ping 1.1.3.2 PING 1.1.3.2: 56 data bytes, press CTRL_C to break Request time out Request time out Request time out Request time out Request time out --- 1.1.3.2 ping statistics --- 5 packet(s) transmitted 0 packet(s) received 100.00% packet loss The output on SwitchA shows that the log host is unreachable, which indicates that a fault occurs on the link between SwitchA and the log host. Step 2 Run the tracert command. # Run the tracert command on SwitchA to locate the faulty link segment. <Quidway> tracert 1.1.3.2 traceroute to 1.1.3.2(1.1.3.2), max hops: 30 ,packet length: 40 1 1.1.1.2 4 ms 5 ms 5 ms 2 * * * 3 * * * 4 * * * 5 * * * 6 * * * 7 * * * 8 * * * ... The preceding output shows that the ICMP Echo Request packet passes SwitchB but does not reach SwitchC. This indicates that the link between SwitchB and SwitchC fails. After the link between SwitchB and SwitchC is recovered, repeat Step 1 and Step 2 to ensure that SwitchA and the log host can communicate properly. ----End

How to Configure Interface-based Multicast VLAN Replication of Huawei S2300/S3300 Series Switch

Networking Requirements for Configuring Interface-based Multicast VLAN Replication of a Huawei S2300/S3300 Series Switch As shown in the below picture, Eth0/0/1 of the SwitchA is connected to the Router. Eth0/0/2 provides services for ISP1, and Eth0/0/3 provides services for ISP2. ISP1 and ISP2 use multicast VLAN 2 and VLAN 3 respectively to provide multicast services for users. Eth0/0/2 and Eth0/0/3 have the same user VLAN (VLAN 10). To protect interests of the ISPs and ensure that multicast packets of each ISP are sent only to users of the ISP, the interface-based multicast VLAN replication is required. After the configuration is complete, multicast data of an ISP will be sent only to the interface connected to the ISP.

Configuration Roadmap for Configuring Interface-based Multicast VLAN Replication of a Huawei S2300/S3300 Series Switch The configuration roadmap is as follows: 1. Enable IGMP snooping in the system view. 2. Create user VLAN 10. 3. Create multicast VLANs 2 and 3 and enable IGMP snooping in the multicast VLANs. 4. Bind user VLAN 10 to multicast VLANs on Eth0/0/2 and Eth0/0/3 respectively. 5. Add the network-side interface and user-side interfaces to VLANs as hybrid interfaces

How to Optimize System Performance by Discarding Certain ICMP Packets of a Huawei S2300/S3300 Series Switch

Networking Requirements for Optimizing System Performance by Discarding Certain ICMP Packets of a Huawei S2300/S3300 Series Switch The switch in the picture below, functions as the aggregation device. Enterprise users, individual users,and DSLAMs are attached to the switch and the switch is connected to the Internet through a BRAS. When a large amount of information is exchanged on the network or the network is attacked, lots of ICMP packets are forwarded and the network performance is degraded. In this case, some ICMP packets are required to be discarded to reduce the burden on the switch.

Configuration Roadmap for Optimizing System Performance by Discarding Certain ICMP Packets of a Huawei S2300/S3300 Series Switch The configuration roadmap is as follows: Configure the function of discarding ICMP packets whose TTL value is 1, ICMP packets that carry options, and ICMP destination unreachable packets to reduce the burden of the device in processing a large number of ICMP packets.

Procedure for Optimizing System Performance by Discarding Certain ICMP Packets of a Huawei S2300/S3300 Series Switch Step 1 Configure the device to discard certain ICMP packets. # Configure the device to discard ICMP packets whose TTL value is 1. <Quidway> system-view [Quidway] icmp ttl-exceeded drop all # Configure the device to discard ICMP packets that carry options.

Networking Requirements for Implementing Inter-VLAN Communication Using VLANIF Interfaces of Huawei S2300/S3300 Series Switch Users in an enterprise use different services and locate at different network segments. Users who use the same service belong to different VLANs and they want to communicate with each other. As shown in the below, User 1 and User 2 use the same service but belong to different VLANs and locate at different network segments. User 1 wants to communicate with User 2.

Configuration Roadmap for Implementing Inter-VLAN Communication Using VLANIF Interfaces of Huawei S2300/S3300 Series Switch The configuration roadmap is as follows: 1. Create VLANs on the switches for different users. 2. Add interfaces to VLANs so that packets of the VLANs can pass through the interfaces. 3. Create VLANIF interfaces and configure IP addresses for the VLANIF interfaces to implement Layer 3 communication.

NOTE To implement communication between VLANs, hosts in each VLAN must use the IP address of the corresponding VLANIF interface as the gateway address.
