Packets Transmitted 64 Octets?
We deploy these on our robots because they are small, fast, and most importantly, are managed.
We'd like to measure/track the packet sizes that are being exchanged so some systems are sending large volumes of small packets.
I found this MIB and other similar ones for receive: RX 64 Octets = '1.3.6.1.2.1.16.1.1.1.14.port'
But I can't find a MIB that is supported by the GS108TV3 that will return information for TX
Packets Transmitted 64 Octets (or) Packets RX and TX 64 Octets
Since these are showing up on the web page, I assume they are supported somehow - I have searched the documentation and downloaded the MIB files, but can't find anything useful. I found some references to a MIB parent at 1.3.6.1.4.*, but snmpwalk on that parent reports No Such Object available on this agent at this OID.
Any ideas or thoughts on how I might resolve this?
Thanks for your time,
Ricky
btw, I plugged my computer into port #1# for a bit, move my computer to a new port (which means port #1 has 'non-changing' values. I then did an snmpwalk and searched the output for values in the output that matched the web page port detailed stats for port #1 - I could match RX values for 64 octets, but not for TX or for the combined RX and TX values.

These are indeed very affordable small swiches, supporting the industry standard SNMP MIBs, just like all Netgear Smart Managed Switch and Managed Switch class models do.
Not that this does change anything for your use case (and the question), Netgear does not count these GS108Tv3 to the Mangaged Switch class, thus I'll challenge a moderator to move your thred to the appropriate Plus and Smart Switches Forum to discuss Smart Switches (T) and Plus Switches (E), including Local and Remote Management.
In other words: Not every switch with an SNMP implementation, with an optional CLI, is a Managed Switch. an often seen misinterpretation in many posts.

These are probably counted internally, and made visible in the Web UI - but these are not a part of a standard MIB implementation.

This is the standardized starting point for the so called private or enterprise OIDs
{iso(1) identified-organization(3) dod(6) internet(1) private(4) enterprise(1)}

Consider to capture what need from the switch Web UI instead of SNMP.
Should you have a demand for a larger number of these switches, talk to Netgear, they might be able to create a custom solution for your business use case.

At so many levels, this is a great reply - thanks for taking the time and being so diligent to provide useful information.
We do have software for navigating the web interface to extract data - so as a last resort that is possible - however we'd like to not release production code that relies on navigating the web page if possible.
These switches are magical for robotics as they are quite configurable and adjustable as needs change. The ability to turn off ports through software so random folks can't plug into a 'developer' without it being authorized or allowed is a small, but important piece. We also can get alerts when ports come up, for a system with lots of computers, just knowing the Ethernet port came up means we know the computer on the other end came up at least the OS is operating due to traffic.
Given your response, I will accept we can't get TX packet size reports and move on. (At the end of the day - it is not a huge value, but something useful.) We can also run wireshark and count for the cases where it really matters - wireshark or other tools are just not as clean as having the switch do it.
Thanks for your time,
Ricky
