The SNMP Tool Screen

2. After “<SET> OID (=|F9)” appears, specify an OID by the same

methods used in the GET procedure:

3. Press the Return key.

If there is no instance of that OID, “MIB NO INSTANCE” will appear;

otherwise “DATA TYPE:” appears.

4. Designate a data type for the OID: integer, string, null, OID, IP

address, counter, gauge, timeticks, and opaque are the available

options. (Refer to the MIB for proper data type.) Press the Return key

to accept the designation.

5. After “DATA” appears, enter the MIB object’s new value and press

Return.

If accepted, “<SET> OPERATION CODE: xxxx <OK>” appears,

otherwise an error message appears.

5.9.10 REPEAT

The REPEAT command is the same as a GET command expect that it

re-executes itself continuously, scrolling updated values for the specified

OID on the screen and counting the number of times it has been shown,

until stopped by the user. In other words, by using REPEAT the user can

monitor an object’s changes over time.

5.9.11 Firmware Image Downloads

The SNMP Tool screen may be used to initiate a Flash file download. The

user will need to know the IP address of the TFTP server and the full path

name of the firmware image to be downloaded from that server.

Set the following OIDs as prescribed below in order to properly initiate

and complete the download.

• ctDLForceOnBoot - 1.3.6.1.4.1.52.4.1.5.8.1.1.0

Cabletron’s Download Force On Boot OID determines whether the

STHI will force a Flash image download at next reset or will boot from

its current Flash file. Set this integer value to 1 to force the download

(or 0 to disable).

• ctDLTFTPRequestHost - 1.3.6.1.4.1.52.4.1.5.8.1.4.0

Cabletron’s Download TFTP Request Host OID holds the IP address

of the designated TFTP server. Set it to the IP address of the TFTP

server which contains the image to be downloaded.
