That's an Open vSwitch extension error code. The format is defined in
include/openflow/nicira-ext.h:
/* Nicira vendor-specific error messages extension.
*
* OpenFlow 1.0 has a set of predefined error types (OFPET_*) and codes (which
* are specific to each type). It does not have any provision for
* vendor-specific error codes, and it does not even provide "generic" error
* codes that can apply to problems not anticipated by the OpenFlow
* specification authors.
*
* This extension attempts to address the problem by adding a generic "error
* vendor extension". The extension works as follows: use NXET_VENDOR as type
* and NXVC_VENDOR_ERROR as code, followed by struct nx_vendor_error with
* vendor-specific details, followed by at least 64 bytes of the failed
* request.
*
* It would be better to have a type-specific vendor extension, e.g. so that
* OFPET_BAD_ACTION could be used with vendor-specific code values. But
* OFPET_BAD_ACTION and most other standardized types already specify that
* their 'data' values are (the start of) the OpenFlow message being replied
* to, so there is no room to insert a vendor ID.
*
* Currently this extension is only implemented by Open vSwitch, but it seems
* like a reasonable candidate for future standardization.
*/
/* This is a random number to avoid accidental collision with any other
* vendor's extension. */
#define NXET_VENDOR 0xb0c2
/* ofp_error msg 'code' values for NXET_VENDOR. */
enum nx_vendor_code {
NXVC_VENDOR_ERROR /* 'data' contains struct nx_vendor_error. */
};
/* 'data' for 'type' == NXET_VENDOR, 'code' == NXVC_VENDOR_ERROR. */
struct nx_vendor_error {
ovs_be32 vendor; /* Vendor ID as in struct ofp_vendor_header. */
ovs_be16 type; /* Vendor-defined type. */
ovs_be16 code; /* Vendor-defined subtype. */
/* Followed by at least the first 64 bytes of the failed request. */
};
Once you extract the inner type and code, you can look it up in the
table in lib/ofp-errors.h. It'll be one of the ones marked "NX"
(Nicira extension):
