Poller Cisco Catalist 6000

Good afternoon.
There are Cisco equipment with a large number of ports and vlans.
The poll takes very long 2k seconds - this is provided that I have fulfilled almost all the conditions from the page:

Another monitoring system or snpwalk (provided that librenms is off) - the poll is very fast. As soon as we enable Librenms - even snmpwalk works slowly.

How to reduce port poll? Port monitoring is important.

Check docs for per port polling try that with this device.

"Per port polling - experimental"
Do you mean it?

I at all vlans made “turn off” and “ignore”.
“Misc” - “Enable selected port polling?” - ON

Yes that’s right.
