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.

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.

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.
