Hi stem

Why Does the dscp Priority of the Outgoing Packets Obtained by the S5300 Port Mirroring Different from the dscp Priority of the Packets Sent by the Interface?

Hi@ster
On an S series switch, if the inbound and outbound directions trust different priorities (for example, the inbound direction trusts the 802.1p priority and the outbound direction trusts the dscp priority), the dscp value of the packets sent by the interface may be different from the dscp value of the original packet. The dscp value queried through port mirroring is the same as the dscp value in the original packet. This is because the port mirroring function is performed before the dscp mapping is complete. In this case, the obtained dscp value is not changed
