Whether the S-series switches block the protocol port

How do I block a Designated Port. on an S series switch?
You can perform the following operations to block a Designated Port on an S (except the S1700) series switch: 1. Run the stp priority command to set the priority of a switch. 2. Run the stp cost command to set the path cost of a port. 3. Run the stp port priority command to set the priority of the port.

Will ports be blocked when two S series switches are connected using two Ethernet cables
If STP is enabled globally and on the ports of two S (except the S1700) series switches, one of the two connected ports of the two switches will be blocked.

SNMP port numbers of S series switches
After SNMP is configured on S series switches (except S1700), UDP ports are enabled by default. By default, the port number for SNMP and NMS connection is 161 and the port number for sending alarms to the NMS is 162.
You can use the snmp-agent udp-port port-num command to configure the port number for SNMP and NMS connection.

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 the S-series switch can view the port number of the connection
The S series switches can not use the CLI to view the port number of the data packets. You can only view the data from which port into refer to source mac by using the display mac-address. You can capture the data through the capture package software named wiresharp to view.
