awwalk-Retrieve Value of Every Attribute Defined in the MIB

Valid on UNIX/Linux, Windows, z/OS

awwalk retrieves the value of every instance of every attribute defined in the MIB, from the specified OID through the last OID in the tree, inclusive. Walking the MIB is the equivalent of repeated calls to awnext. If you use the -o option, the attribute OID is printed followed by the OID value.

This utility is most useful for obtaining all the values of the attributes in a MIB, group, table, or column. Specify the top (root) OID, group OID, table OID, or the OID of the first attribute in a column to see the values of all subordinate OIDs.

UNIX/Linux, z/OS

Many UNIX/Linux nodes have a MIB II-compliant SNMP agent built into the operating system, as does z/OS. These agents are hard coded to listen for manager requests on UDP port number 161. To prevent port conflicts between the operating system agent and your agent, the SNMP Administrator defaults to listening for requests on UDP port number 6665.

z/OS JCL

&CAI.MFNSM.CAW0JCL(AWWALK)

This command has the following format:

awwalk [-h hostname ] [-c community] [-p service] [-o] OID [-t timeout]

-h hostName\ipaddr

Specifies the host name or IP address of the node on which the agent is running.

Default: local node

-c community

Specifies the name of any valid community in the agent configuration.

If you want to retrieve the MIB attribute value from a specific instance of an agent, then you need to postfix the community string with the @ sign, followed by the specific agent's instance name.

Default: public, which is supported for read

-p service

Specifies the name in the /etc/services file that translates to a port number, or the number of the UDP port where the agent listens for incoming requests. This value must match the one used by the SNMP Administrator, which is normally 6665.

Default: 6665 for z/OS

-o OID

Specifies the object identifier of any node in the agent's MIB where you want to begin traversing the tree.

-t timeout

Specifies the maximum time value (in seconds) this program waits for a response to an SNMP request before exiting.

Default: 10 seconds
