The ONS-XC-10G-S1 XFPs used on the MSTP 10GE TXPs with a part number of 10-2012-01 and a serial number starting with ECL shows an anomalous behavior in Y-cable configuration.
Testing has shown the device 10-2012-01 with a Serial Number starting with the letters ECL failed the switch test on a Y-cable configuration, exceeding the allowed switching time.
This issue only impacts the 15454 MSTP TXP when used in a Y-cable protection configuration. These disruptions were seen/detected by way of control plane protocols (Layer 3- BGP specifically) losing neighbor relationships and reporting a problem via SYSLOG and SNMP.
The total time of intervention of the Y cable protection should be in the order of 50 milliseconds.
The parts affected are unable to allow meeting this specification.
Cisco offers to replace the defective parts on failure if they are being used in a Y-cable environment.
In this case, the customer is invited to return the defective (ECL) 10-2012-01 XFP's for replacement.
Cisco will replace the components with a compliant version of the 10-2012-01 or the new Part Number 10-2012-02 version of the part. (Both ECL and OTN serial numbers are good).
