I was tryting to test 802.1CB using LS1028A as a end device. which means swp4 as an inport. and swp0 swp1 swp2 swp3 as outports.
One typical command is as below:
tsntool> cbgen --device swp0 --index 1 --iport_mask 0x3f --split_mask 0x07 --seq_len 16 --
seq_num 2048
before doing the command i need to build the bridge which i can only attach swp0 ~3 to the bridge and can not find swp4.
