| Frame Length Range |
Support 1518Byte～9600Byte message length setting, support Jumbo frames up to 9600Byte. |
| Mapping Method |
N1EAS2: VC-4-Xv (X≤8), VC-3-Xv (X≤24) and VC-4-4c are cascaded adjacent to each other.
N3EAS2: VC-4-Xv (X≤64) and VC-4-4c/16c/64c are cascaded adjacent to each other.
Description:
For N3EAS2 veneer, only VCTRUNK1 and VCTRUNK18 support VC-4-16c/64c adjacent cascade, and other VCTRUNKs only support VC-4-4c adjacent cascade.
The N3EAS2 single board supports only the adjacent cascade of bidirectional services, not the adjacent cascade of unidirectional services.
