Using the SNMP Utilities
4.1 Using the MIB Browser
Table 4–2 (Cont.) Flags for the snmp_request Command
Flag | Description | |
|
|
|
Specifies loop mode. Note that this flag is the letter l, not the number 1. | ||
| Valid only if | |
| 0, and flag m is set to a number greater than 0). | |
| Causes the master agent to traverse all the MIBs registered with the master | |
| agent, starting at the first OID after the one specified in the command. | |
| (Note that you can specify only one | |
| received one at a time, and for each one, the OID returned by the master | |
| agent is used in a subsequent request. Corresponds to the behavior of | |
| standard mibwalk programs. | |
| The MIB browser reads and displays responses, and issues requests until | |
| the master agent has no more data, times out, or you press Ctrl/Y or Ctrl/C. | |
| If specified with the GetBulk request, the | |
| values are ignored, and the behavior is identical to that of GetNext. | |
| When the last OID handled by the master agent is reached, you receive a | |
| response similar to the following for a query on OID 1.3.6.1.6.3.1.1.6.1 using | |
| SNMP Version 1: | |
| 1.3.6.1.6.3.1.1.6.1.0 = 693056825 |
|
| - no such name - returned for variable 1 | |
| For a query using SNMP Version 2, the example response is: | |
| 1.3.6.1.6.3.1.1.6.1.0 = 693056825 |
|
| 1.3.6.1.6.3.1.1.6.1.0 = - end of mib view - | |
| These examples assume that: | |
| • OID 1.3.6.1.6.3.1.1.6.1.0 is the last OID supported on the target host. | |
| • The target host is running an SNMP Version 2 agent. | |
| The statement end of mib view refers to OIDs for all MIBs registered with | |
| the master agent. | |
| Specifies the number of repetitions requested for repeating variables. | |
| Applies only to the GetBulk and GetNext requests. | |
| Note that the resulting display can be confusing because the results for the | |
| repeater OIDs are interleaved. That is, the OIDs are displayed in alternate | |
| progression for faster memory throughput. If you specify GetBulk without | |
| specifying both the | |
| Specifies the number of variables for which no repetition is requested. | |
| Applies only to the GetBulk request. If you specify GetBulk without | |
| specifying both the | |
| Specifies the port where the request is to be sent. If not specified, the | |
| request is sent to |
-r max_retries
Specifies the number of times the MIB browser resends a request packet if it times out before receiving a reply. Specify a positive integer for the value (max_retries). If you specify a negative value, it will be converted to an unsigned positive integer. If you specify 0, no retries are tried.
If, after a timeout and a resend, a reply packet is received, the resend counter is reset. After another timeout, the specified number of max_retries is sent.
