Can mirrored packets be saved

11

Yes. Run the capture-packet command to configure the packet capturing function. The packets captured can be displayed directly on a terminal or be stored in the storage media of the device.

Do S series switches support broadcasting of mirrored packets in a VLAN
Whether mirrored packets are broadcast in a VLAN depends on whether the MAC address table of this VLAN contains entries matching the MAC addresses of the mirrored packets. If the MAC address table of a VLAN contains entries matching the MAC addresses of the mirrored packets, the mirrored packets are forwarded based on the MAC address table at Layer 2. Otherwise, the mirrored packets are processed in the same manner as Layer 2 unknown traffic, that is, they are broadcast in the VLAN. If the MAC address table of a VLAN contains entries matching the MAC addresses of the mirrored packets, and the mirrored packets need to be broadcast in the VLAN, run the mac-address learning disable command in the view of this VLAN to disable MAC address learning (This function applies to all S series switches except S1700 switches.)

Can packets on multiple interfaces be mirrored to one observing port on AR routers and how many interfaces can be mirrored
Multiple interfaces can be mirrored to one observing port on AR routers. There is no limit for the number of interfaces that can be mirrored to one observing port. You need to consider whether actual traffic of the observing port is larger than its forwarding capacity, that is, whether the actual traffic is larger than the maximum bandwidth of the observing port.

Do S series switches support N:1 or 1:N mirroring
S series switches all support N:1 mirroring, in which packets are copied from N mirrored ports to one observing port, and there is no limit on the number specified by N. 1:N mirroring copies packets on one mirrored port to N observing ports. M:N mirroring copies packets on M mirrored ports to N observing ports. In M:N mirroring, the number of mirrored ports is not limited, and the number of observing ports is the same as that in 1:N mirroring. The observing ports supported by S series switches are different.
