[pysnmp-users] bulkcmd works in old example code, but not in new example.

[Gee Z. <tuv...@ou...>]

Old example code: http://pysnmp.sourceforge.net/examples/current/v3arch/oneliner/manager/cmdgen/getbulk-v2c.html


<http://pysnmp.sourceforge.net/examples/current/v3arch/oneliner/manager/cmdgen/getbulk-v2c.html>New example code: http://pysnmp.sourceforge.net/examples/hlapi/asyncore/sync/manager/cmdgen/table-operations.html#fetch-scalar-and-table-variables

I am trying to extract a particular OID (1.3.6.1.2.1.17.4.3.1.1) from a Cisco switch via the bulkcmd function. However, I took reference from your old example and it works. However, when I referenced from your new example, it throws errors as follows:

TypeError: unsupported operand type(s) for +: 'int' and 'str'

I tried removing the for loop in the new example code, but the same error occurred.

Any guidance is deeply appreciated. Cheers.
