copsClientErrWrongOpcode

Module: COPS-CLIENT-MIB

OID (symbolic): COPS-CLIENT-MIB::copsClientErrWrongOpcode

OID (numeric): 1.3.6.1.2.1.89.1.2.1.1.27

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: A count of the total number of COPS messages that this client has received from COPS servers marked for this Client-Type that had a COPS protocol Op Code that should not have been sent to a COPS client e.g. Open-Requests. This value is cumulative since agent restart and is not zeroed on new connections.

What is copsClientErrWrongOpcode?

This read-only Counter32, cumulative since agent restart, counts received messages with an Op Code that should never be sent to a client, such as an Open-Request. It indicates the server is misusing the protocol by sending client-only or otherwise invalid operations. For example, an admin treats a nonzero copsClientErrWrongOpcode as evidence the connected server has a COPS role-reversal bug worth reporting.

Examples
