DSCP priority The system provides 0–63 DSCP priority levels. Each level has four priority types:
High, Middle, Low, and Lowest. When an IP packet is received, the system will check
the DSCP level value in the packet and grant it the appropriate priority. For example,
if you set DSCP level 25 as “High,” and system finds that the DSCP value of the
received IP packet is 25, the packet will receive highest priority.

6.5.11 Port Mirroring
Port mirroring is a method for monitoring traffic in switched networks. Traffic through ports can be monitored by
one specified port, which means traffic going in or out of monitored (source) ports will be duplicated into mirror
(destination) ports.
To set up port mirroring, choose Configure-->Mirroring.
NOTE All the duplicated data of the source port can be separated with RX and TX. If you want to collect
multi-source ports at the same time, you can assign the TX of one destination port to be responsible for
collecting all the TX data of source ports and assign another RX of destination port to be responsible for
collecting all the RX data of source ports.
