Huawei Quidway S3300 series switches are new generation Layer 3 Ethernet switches developed to meet the requirements for reliable access and high-quality transmission of multiple services on the MAN metropolitan area network. Based on the high-performance hardware and Huawei VRP Versatile Routing Platform, the S3300 provides the enhanced selective QinQ function and capability to replicate multicast packets between VLANs at the line speed, and supports carrier-class reliability technologies such as Smart Link (applicable to tree networks) and RRPP (applicable to ring networks), as well as the Ethernet OAM function. Huawei S3300 can be used as access devices in buildings or applied to the access layer and aggregation layer of campus networks.

Q: What is the difference between LS-S3328TP-EI-24S-AC and LS-S3328TP-EI-AC?
A: LS-S3328TP-EI-24S-AC is optical switch, most ports are optical 100Base-X, LS-S3328TP-EI-AC is normal switch, most ports are FE RJ45.
Q: Why the S3300 CPU Usage Is Too High When Many VLANIF Interfaces Are Configured on the S3300?
A: Do not configure many VLANIF interfaces on the S3300 due to limitations on specifications and hardware performance. This prevents attacks to the CPU from numerous ARP packets or ARP Miss messages and overhigh CPU usage.
Run the arp-fake expire-time 30 command in the view of each VLANIF interface to configure ARP entries and reduce the CPU usage. Besides, you are advised to load the latest patch.
Q: Does the S3300 Support Port Mirroring?
A: The S3300 supports port mirroring. The details are as follows:
A maximum of four observing ports can be configured on an S3300 Switch. Packets from multiple ports can be mirrored to the same observing port. You can mirror incoming packets, outgoing packets, or both to an observing port.
The S3300 supports Remote Switched Port Analyzer (RSPAN). That is, the observing port and mirrored port can be located on different switches. This facilitates remote device management.
The S3300 supports traffic mirroring. A maximum of four observing ports can be configured on an S3300. Flows can be mirrored from multiple ports to the same observing port. Flows to be mirrored are determined by the traffic classification rule.
Q: After a Traffic Policy Is Applied Globally on an S3300, the Rate Limit Is Invalid When a Traffic Policy Is Applied to Interface?
A: If more than 128 ACL rules are configured, a traffic policy must be applied to the interface, VLAN, and globally in sequence. To update ACL rules, delete all traffic policies from the interface, VLAN, and system, and reconfigure traffic policies on the interface, in the VLAN, and globally in sequence.
Q: After traffic-remark vlan-id Is Configured on the S3300, the Switch Learns the MAC Address in the Original VLAN. Why?
A: In V100R005/V100R006/V200R001/V200R002, the traffic-remark vlan-id command is executed after the switch learns the MAC address, so the MAC address in the original VLAN but not the VLAN specified by the re-marked VLAN ID is learned.
Q: When the traffic-limit Command Is Configured in the Inbound Direction and the qos lr Command Is Configured on the S3300, the Rate Limit Is Inaccurate. Why?
A: In V100R005/V100R006/V200R0O1/V200R002, both the traffic-limit and qos lr commands limit the traffic rate. Only packets allowed by the two commands can pass through. As a result, some packets of a flow are discarded by qos lr and traffic-limit. The rate limit is inaccurate.
Q: Can the S3300 Switches Be Configured Not to Take Any Action After Detecting Loops?
A: After loop detection is enabled on the S3300 switches:
The switches perform the configured action after detecting a loop.
The action can be changed but cannot be disabled. When the action is changed to trap, the switches only report a trap and do not take any action after detecting a loop.
Q: There Are Multiple Ports in Up State on the S3300. After VLAN Mapping Is Configured on These Ports, Ping Packets Are Lost and Telnet Packets Are Processed Slowly. Why?
A: Scheduling of packet receiving tasks is improver. As a result, packet receiving tasks are switched frequently and there is low efficiency in processing packets. Ping packets are lost and Telnet packets are processed slowly.
Q: Do the S3300 Switches Transparently Transmit BPDUs by Default
A: By default, the S3300 switches do not transparently transmit Bridge Protocol Data Unit (BPDUs).
Q: Why Can the Working Rate of Some Combo Interfaces on the S3300 Be Configured to 100 Mbit/s and Other Combo Interfaces Cannot?
A: You can know the working rate of combo interfaces on the S3300 according to the marks on the panel. The details are as follows:
If a combo interface is marked with 1000M, the working rate of the combo interface can only be 1000 Mbit/s.
If a combo interface is marked with 100/1000M, the working rate of the combo interface can be 100 Mbit/s or 1000 Mbit/s.
