There are various complicated reasons for this, LPTS policer is
unlikely culprit, but possible. Bug search will show various DDTS with
poor SNMP performance outcome, most of them are unrelated to LPTS.

But absolutely correct, the right solution is to escalate. In common
case this would be SE from your account team, who would fight for you
internally.


It is appalling that OP came to nanog after correctly suspecting TAC
is gaslighting them, some community member piled on with what can only
be described as a bizarre drivel.
