I want to know the SNMP protocol (OID) of product 'PTP 545'

Can I know the mail or path of the SNMP protocol (oid) document of product ‘PTP 545’ ?

I don’t believe we’ve ever sold a “PTP 545”. There was a PTP 54500, which is the 5.4GHz variant of the PTP-500, and there is a PTP-450. Is it one of these?

oh! Exactly!
Can you provide ‘PTP 54500 oid’??

If you download PTP 500 Software Release 05-04 from https://support.cambiumnetworks.com/files/ptp500/, you will find the MIBs in the zip file.
