CFI Carried
Untagged frames received (If Input Force No Tag is
enabled, Samurai-6M/6MX (ADM6996M/MX) assumes
all the received packets are untagged.)
Tagged frame received
3.1.14.15 Egress TAG
Egress tag contains Egress PRI, Egress CFI, and Egress VID. When packets are transmitted tagged, this egress
tag associated with Ethernet-Type = 8100
Egress PRI: Egress PRI is Tagged PRI carried through Samurai-6M/6MX (ADM6996M/MX) from the source port.
Egress CFI: Egress CFI is CFI carried through Samurai-6M/6MX (ADM6996M/MX) from the source port.
Egress VID: Egress VID is VID carried through Samurai-6M/6MX (ADM6996M/MX) from the source port.
3.1.15
Samurai-6M/6MX (ADM6996M/MX) supports 4 priority queues and each is assigned a weight.
Reserve PRI is reversed from the priority queue the packet is switched through.
Compare = queue, queue, queue, queue} XOR VLAN Priority MAP in 000E
Then we get Tagged PRI.
