Can data packets be blocked in the control VLAN of RRPP

1

Data packets are not blocked in the control VLAN though the control VLAN is configured in the instance.

Can protocol packets be sent if an interface with a loop detected is blocked on an S series switches
Can protocol packets be sent if an interface with a loop detected is blocked on an S series (except the S1700) or E series switch? For S series switches (except the S1700), the destination MAC address of LDT packets and tagged LBDT packets is all Fs. These packets cannot be sent through an interface if it is blocked. The destination MAC address of untagged LBDT packets is a BPDU MAC address. These packets can still be sent through an interface even if it is blocked. For E series switches, the destination MAC address of tagged LBDT packets is all Fs. These packets cannot be sent through an interface if it is blocked. The destination MAC address of untagged LBDT packets is a BPDU MAC address. These packets can still be sent through an interface even if it is blocked.

Whether observing-port of S-series switch can distinguish the mirrored traffic of different VLANs
For S-series switches, because the mirrored traffic is copied directly from the original traffic, the traffic mirroring to the observing port is related to whether the port carry the VLAN tag and the direction of mirrored port. - Inbound of mirroring traffic: For the Access port type, because the original traffic do not carry VLAN tag, the mirrored traffic to the observing port do not have VLAN tag; For Trunk type port, because the original traffic carry VLAN tag, the mirrored traffic to the observing port has a VLAN tag too; The hybrid port has both of the above two cases. - Outbound of mirroring traffic: For some switches, the mirroring action occurs before adding / stripping VLAN tags, because the original traffic from the device before the general release with a VLAN tag, the mirror to the observation port has a VLAN tag too; For another Part of the switch, the mirror action occurs after adding / stripping VLAN tags, so whether mirroring to the observing port carry VLAN tag is same as inbound of mirroring traffic style.

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.)

Does network flapping occur when new data VLANs are added to an RRPP ring comprised of S series switches
Network flapping does not occur when new data VLANs are added to an S series switch (except S1700) in an RRPP ring. However, updates of MAC address entries and ARP entries may cause loss of few packets.
