mplsCemVcDefects

Module: MPLS-CEM-MIB

OID (symbolic): MPLS-CEM-MIB::mplsCemVcDefects

OID (numeric): 1.3.6.1.3.9999.1.2.1.31

Node type: OBJECT-TYPE

Type: Bits

Access: read-only

Description: Current state of these CEM VC defects. The cemError indicator is a summary of any error associated with processing inbound CEM packets. Separately displaying CEM errors types (buffer errors, missing packets, and header errors) are for future study. Also other bits here may be defined here to show results of error trend analysis. These bits MUST be aligned with mplsCemVcApsCriteria bits so mplsCemVcApsCriteria can

be used as a mask. Note: other defect indications (e.g. from OAM) are for future study.

What is mplsCemVcDefects?

Reports the CEM VC's current defect state as a bitmask; the cemError bit summarizes any inbound-packet processing error (buffer errors, missing packets, header errors), and is defined to line up bit-for-bit with mplsCemVcApsCriteria so that field can be used as a mask against this one.
