polling on port other than 161

 you can define the port in the Node details page from the system mgr or website under Node mgt -> edit properties.

I did this and it works for me.  Although if you need to poll on more than one port, it gets tricky.

aynov,

What do you mean it gets tricky if I need to poll on more than one port??

 Mark,

I just tried changing the port to 260 under the system manager and the node itself, and it does not verify that it works. I checked firewall rules and it is allowed via 260.

I tried to use the UDP and  browse the MIB tree but that times out as well when it is set to 260.

We just received a request to change the SNMP port for a particular server.  I tried changing the port from 161 to 50161 but System Manager won't apply change permanently.  Changed the port number to 50161, clicked on Validate SNMP button and returns 'Node Validation Successful', clicked Apply Changes, then closed panel.  Reopened Node Details and SNMP port is still 161.  What gives?  Is this a bug?  Is there workaround?  I have a server I cannot poll now.  We're running v8.5.1 SP3.

RG,

Seems like a bug to us.  You can open a ticket, and we'll see if we can reproduce it on 9.1 SP1 (soon to be SP2).  If it's still broken, we'll fix it on the 9.1 branch.  It's unlikely that we'll go back to 8.5.1.

 We had a bit more discussion about this after Denny appears to have gone back to jury duty.  It looks like in this case, we limit the max port number to 32767(signed 16 bit instead of unsigned).  If you can get the device to use a port number below that, you should be fine.

we limit the max port number to 32767(signed 16 bit instead of unsigned)

Thank you and Denny for your quick responses on this.  This is an Openview system running the EMANATE Agent (SNMP Research) which was installed during the product installation.  I don't know if this can be done but we'll have to contact HP to see if this is possible.  I can't find where the port is configurable.  They'll probably tell us to contact SNMP Research.  Any chance the limit on the port number can be bumped to 64K?

Edit: I found the file (C:\Windows\system32\drivers\etc \services) where to change the port number so we can change it.  Still would like to request the limit be bumped to 64K.

The best way to make sure we get this into our system is to open a support ticket and reference this Thwack thread.  That will get the ball rolling.  It also has the advantage of when the issue is fixed, you'll get notified by support.

Done.  Case #70998

Thanks Casey!
