Which ports are used in SNMP?
To sum up, SNMP uses the UDP port 161 of the SNMP Agent for sending and receiving requests, and port 162 of the SNMP Manager for receiving traps from managed devices. Every device that implements SNMP must use these port numbers as the defaults. These two ports are the same in all versions of SNMP, since SNMP v1.
What port is SNMP and its function?
SNMP is an application layer protocol that uses UDP port number 161/162. SNMP is used to monitor the network, detect network faults, and sometimes even used to configure remote devices.
Is port 161 UDP or TCP?
Well-known ports
| Port | TCP | UDP |
|---|---|---|
| 156 | Yes | Yes |
| 158 | Yes | Yes |
| 161 | Assigned | Yes |

Are SNMP traps UDP or TCP?
SNMP traps are sent on UDP port 162. The manager sends polls on port 161 and listens for traps on port 162.
Is port 162 UDP or TCP?
Service Name and Transport Protocol Port Number Registry
| Service Name | Port Number | Transport Protocol |
|---|---|---|
| sgmp-traps | 160 | udp |
| snmp | 161 | tcp |
| snmp | 161 | udp |
| snmptrap | 162 | tcp |
Does SNMP v3 use TCP?
While TCP can be used for SNMP, it was originally designed with UDP transport only. Therefore, typically, SNMP uses UDP port 161 and UDP port 162. Note: Agents use UDP 161, while the manager uses UDP 162.
