SNMP Operators with examples
| SNMP Operator | Applicable Type | Syntax | Return Type | Example | Example Result | Description |
|---|---|---|---|---|---|---|
| "=" or "==" | Number | a=b or a==b | Boolean | 3=4 or 3==4 | FALSE | To check the equality of two operands, return true if the two values are the same; otherwise, return false. |
| "!=" or "<>" | Number | a!=b or a<>b | Boolean | 3!=4 or 3 <> 4 | TRUE | To check the not equal condition between two operands, return true if both values are not equal; otherwise, return false. |
| ">" | Number | a > b | Boolean | 3 > 4 | FALSE | To check the greater than condition between two operands, return true if the left-side value is greater than the right-side value; otherwise, return false. |
| "<" | Number | a < b | Boolean | 3 < 4 | TRUE | To check the less than condition between two operands, return true if the left-side values is less than right side value; otherwise, return false. |
| ">=" | Number | a>=b | Boolean | 3>=4 | FALSE | To check the greater than or equal condition between two operands, return true if the left-side value is greater than or equal to the right-side value; otherwise, return false. |
| "<=" | Number | a<=b | Boolean | 3<=4 | TRUE | To check the less than or equal condition between two operands, return true if the left-side value is less than or equal to the right-side value; otherwise, return false. |
| "+" | Number | a+b | Number | 3+4 | 7 | It will return the result after adding the two operands. |
| "-" | Number | a-b | Number | 4-3 | 1 | It will return the result after subtracting the right side value from the left-side value. |
| "*" | Number | a*b | Number | 3*4 | 12 | It will return the result after multiplying the two operands. |
| "/" | Number | a/b | Number | 3/4 | 0 | Divides the first operand by the second and returns the result. |
| "%" | Number | a%b | Number | 4%3 | 1 | Returns the remainder when the first operand is divided by the second. |
| ">>" | Number | a>>b | Number | 100>>2 | 20 | The right shift operator (>>) shifts the bits of the right operand to the right by the number of times specified by the right operand. |
| "<<" | Number | a << b | Number | 100 << 2 | 400 | The left shift operator (<<) shifts the bits of the left operand to the left by the number of times specified by the left operand. |
| "^" | Number | a^b | Boolean | 2^4 | 16 | The bitwise XOR (^) operator performs a binary XOR operation bit by bit on the operands. |
| "||" | Number | a || b | Boolean | 1 || 0 | TRUE | The symbol || denotes the OR operator. This operator will only return false when both conditions are false. |
| "&&" | Number | a && b | Boolean | 1 && 0 | FALSE | The symbol && denotes the AND operator. It evaluates two statements/conditions and returns true only when both statements/conditions are true. |
| eq | String | a eq b | Boolean | 'abc' eq 'xyz' | FALSE | Equality checking of two strings, return true if both Strings are the same. |
| ne | String | a ne b | Boolean | 'abc' ne 'xyz' | TRUE | Inequality checking of two strings, return false if both Strings are the same. |
| "=~" | String | a' =~ 'b' | Boolean | 'abcd' =~ 'abc' | TRUE | If the left-side String value contains the right-side String value, it will return true. |
| "!~" | String | a' !~ 'a' | Boolean | 'abcd' !~ 'abc' | FALSE | If the left-side String value does not contain the right side String value, it will return true. |
SNMP Functions with examples
