The port-mirroring slice-size command configures the length of packet for mirrored traffic.
The undo port-mirroring command deletes the configuration of packet length for mirrored traffic.
By default, no function of packet length truncation for mirrored traffic is configured on the Device.

Usage Scenario
In heavy-traffic scenarios, if the original packet is large and you only need to mirror packets of a specified length, run this command to specify a packet length for mirrored traffic. You can use this command and the user-defined offset mirroring function to obtain specific packet segments, reducing the bandwidth used by the observing port and improving service performance.
Prerequisites
Before running this command on an interface, you must run the port-mirroring or port-mirroring inbound pe-vid ce-vid command.
Precautions
After the port-mirroring slice-size configuration is run on interface, if the port-mirroring or port-mirroring inbound pe-vid ce-vid configurations has been deleted, the configuration of port-mirroring slice-size will also be deleted.
