-d

Specifies hexadecimal dump mode. Before displaying a return value, displays

 

a hexadecimal dump of SNMP packets sent and received. For example:

 

$ snmp_request host1 "public" getnext -d -v 2c 1.3.6.1.6.3.1.1.6

-imax_ignores

Specifies the number of times the MIB browser listens for a reply packet

 

to a request if it receives an invalid packet (caused by an invalid packet

 

identifier, version, or SNMP version and command combination). Specify a

 

positive integer for the value (max_ignores). If you specify a negative value,

 

it will be converted to an unsigned positive integer. If you specify 0, no

 

retries are attempted.

 

 

If, after an invalid reply packet is received, a valid reply packet is received, the ignore counter is reset to the value of max_ignores.

If a timeout occurs after an invalid packet is received, the packet is resent, the resend counter is decremented, and the ignore counter is reset to the value of max_ignores.

You cannot use the -iflag when you perform a query with the -lor -tflags to automatically increment the input OID and continue querying a server after a general SNMP error has occurred, as may happen with a faulty server. In this case, the query is terminated even though the end of the MIB selection has not been reached. You must manually increment the input OID to skip the error and continue with the query.
