| VCTRUNK Specifications |
The number of VCTRUNK for N1EAS2 is 24. Configuration Features: After a VC channel of each level is used by one VCTRUNK binding, other VCTRUNKs can no longer be used. Each VCTRUNK can be bound to a maximum of 8 VC-4s or 24 VC-3s. The same VCTRUNK cannot bind both VC-4 and VC-3 channels, only one. Different VCTRUNK can bind different levels of channels. Support VC-4-4c adjacent cascade, VC-3/VC-4 dummy cascade. Only VCTRUNK1 ~ VCTRUNK4, 4 VCTRUNKs support 9600-byte Jumbo frames, other VCG ports do not support Jumbo frames.
The number of VCTRUNKs for N3EAS2: When the slot bandwidth is 10Gbit/s, the number of VCTRUNKs supported is 17 (i.e., VCTRUNK1 to VCTRUNK17). When the slot bandwidth is 20Gbit/s, the number of VCTRUNKs supported is 34 (i.e., VCTRUNK1 to VCTRUNK34).
Configuration features: After a VC channel of each level is used by one VCTRUNK binding, other VCTRUNKs can no longer be used. The maximum number of VC-4s that can be bound to VCTRUNK1 and VCTRUNK18 is 64, and the maximum number of VC-4s that can be bound to other VCTRUNKs is 8. VCTRUNK1 to VCTRUNK17 can only bind channels from 1 to 64 VC-4, and VCTRUNK18 to VCTRUNK34 can only bind channels from 65 to 128 VC-4.
