Parameters
8: Specifies the modulus value to be 8.
128 : Specifies the modulus value to be 128.
Usage guidelines
LLC2, like X.25, uses modulus to number frames. All frames sent are numbered incrementally and await
an acknowledgment. When the frame number reaches the configured value (called "modulus value"),
subsequent frames are numbered from 1 again. For example, if the modulus value is set to 8, frames are
numbered …4, 5, 6, 7, 0, 1, ....
LLC2 supports two modulus values: 8 or 128. 128 is usually used for Ethernet frames.
Examples
# Set the modulus value for LLC2 frames to 8 on Ethernet 1/0.
<Sysname> system-view
[Sysname] interface ethernet 1/0
[Sysname-Ethernet1/0] llc2 modulo 8
llc2 receive-window
Use llc2 receive-window to configure the maximum number of consecutive information frames the router
