Functions and Features of the LSH7D18DX2E0
Functions and Features
Description
Basic function
Provides data packet processing and traffic management on 18 x 400GE optical ports, which can be used as 18 x 100GE or 18 x 40GE optical ports, or split into up to 54 x 100GE optical ports.
Maximum port density
If all LPUs are these cards:
The S16700-4 chassis provides a maximum of 72 400GE ports.
The S16700-8 chassis provides a maximum of 144 400GE ports.
400GE port
Supports QSFP-DD, QSFP28, and QSFP+ optical modules. The 18 optical ports are independent, and each 400GE port can be used as a 100GE or 40GE port through auto-sensing. The 400GE ports 0 to 3, 6 to 9, and 12 to 15 can be split into 4 x 100GE ports. Other ports cannot be split.
Hot swapping
Supported
MACsec
Ports 0 to 3, 6 to 9, and 12 to 15 support MACsec. Other ports do not support MACsec.
Restrictions and remarks
Every six ports (ports 0 to 5, 6 to 11, and 12 to 17) form a group, to which the following limitations apply:
Only the first four ports in each group (ports 0 to 3, 6 to 9, and 12 to 15) support up to 1.6 Tbit/s forwarding. If the service bandwidth does not reach 1.6 Tbit/s, all the six ports in each group can be used.
When SFUs work in 3+1 mode, the maximum bandwidth of each group cannot exceed 1.2 Tbit/s (for example, 3 x 400 Gbit/s).
When SFUs work in 4+0 mode, the maximum bandwidth of each group cannot exceed 1.6 Tbit/s (for example, 4 x 400 Gbit/s).

LSH7D18DX2E0 FAQ
Q1: Which optical modules are supported? Can existing 1G SFP optical modules be used?
A1: Supports Huawei SFP+/SFP series optical modules. SFP+ modules (SR/LR) are used for 10G, and SFP modules are used for 1G. Existing 1G optical modules can be directly reused, reducing upgrade costs.
Q2: What is the maximum number of terminals supported?
A2: A single port can stably connect 30-40 terminals, and a total of 500-700 terminals can be supported across 18 ports, meeting the needs of medium to large-scale aggregation scenarios.
Q3: What are the differences between this and other Huawei 10GE boards (such as ET1D2VS08000)?
A3: Focused on high-density aggregation, with more ports (18 ports vs. 8 ports), it offers better cost-effectiveness and is suitable for aggregation layer scenarios requiring large-scale 10G access.
