When a QSFP+ to QSFP+ high-speed cable is installed on a port, the cable can only be used as a cable of an M-LAG peer-link interface.
Functions and Features of the LSH7C18HX1E0
Functions and Features
Description
Basic function
The card provides data packet processing and traffic management on 18 100GE optical ports, which can be used as 18 40GE optical ports or split into 72 25GE or 72 10GE optical ports.
Maximum port density
If all LPUs are such cards:
The S16700-4 chassis provides up to 72 x 100GE ports.
The S16700-8 chassis provides up to 144 x 100GE ports.
100GE port
100GE ports on the card support QSFP28 and QSFP+ optical modules. A 100GE port can be used as a 40GE port through auto-sensing, or split into four 25GE or four 10GE ports.
That is, a card can provide a maximum port density of 18 x 100GE, 18 x 40GE, 72 x 25GE, or 72 x 10GE.
All the 18 100GE ports are independent, and each port can be used as a 40GE port through auto-sensing, or split into four 25GE or four 10GE ports.

LSH7C18HX1E0 FAQ
Q1: Which optical modules are supported? Can existing 1G optical modules be reused?
A1: Supports Huawei SFP+/SFP series optical modules. 10G uses SFP+ (SR/LR), and 1G uses SFP modules. Existing 1G optical modules can be directly reused, reducing upgrade costs.
Q2: What is the maximum number of terminals supported by a single service board?
A2: A single port can stably connect 30-40 terminals. A total of 24 ports can support 700-900 terminals, meeting the needs of medium to large-scale aggregation scenarios.
Q3: What are the differences between this board and Huawei LSH7C36HX2E0/LSH7D18DX2E0?
A3: The number of ports is moderate (24 vs 36/18), offering a better balance between capacity and cost, suitable for medium to large-scale scenarios that "do not require ultra-high density but need more ports than 18."
