Summary:Some ATN 950B versions mistakenly report mismatch alarms about newly added TPP1XGKZRCZABE2G/FTLX1871M3BCL/SPP5100ZX-H1 10G optical modules due to inappropriate identification criteria.
Product Line: Router&Carrier Ethernet Product Family: ATN
An ATN 950B running V200R002C00SPC300/V200R003C00SPC100/V200R003C00SPC200/V200R003C10SPC100/V200R003C10SPC700/V200R003C20SPC100 is equipped with an AND2EX1S/AND2EX2S subcard.
TPP1XGKZRCZABE2G/FTLX1871M3BCL/SPP5100ZX-H1 10G optical modules (BOM number: 34060672) are installed on the AND2EX1S/AND2EX2S subcard of the ATN 950B.
The optical modules are 10G SFP+ optical modules that have a transmission distance of 80 km and wavelength of 1550 nm.
After the display alarm all command is run on the ATN 950B, The optical module did not match. [GigabitEthernet 0/5/0] can be found in the command output.
1 Run the display device pic-status command on the ATN 950B to check whether the device uses AND2EX1S or AND2EX2S subcards.

6 Registered ETH_AND2EX2S_CARD 1 SUCCESS SUCCESS
Then, run the display interface GigabitEthernet 0/5/0 command to check whether the optical module model is TPP1XGKZRCZABE2G/FTLX1871M3BCL/SPP5100ZX-H1.
Here, 0/5/0 represents the number of the interface where a 10G optical module resides. Only 10G optical modules have mistakenly reported mismatch alarms

2 If the check results are positive in the preceding step, the problem described in this precaution notice has occurred, but no action is required.
The criteria used by the ATN 950B to identify newly added TPP1XGKZRCZABE2G/FTLX1871M3BCL/SPP5100ZX-H1 10G optical modules are too strict.
[Impact and Risk]
The mismatch alarms about newly added TPP1XGKZRCZABE2G/FTLX1871M3BCL/SPP5100ZX-H1 10G optical modules are mistakenly reported, but do not affect live network services.
[Measures and Solutions]
The mistakenly reported alarms do not affect services, and no recovery measure is required.
The mistakenly reported alarms do not affect services, and no workaround is required.
For ATN 950B V200R003C00SPC100/V200R003C00SPC200/V200R003C10SPC100/V200R003C10SPC700/V200R003C20SPC100, install ATN 950B V200R003SPH008 or a later patch. ATN 950B V200R003SPH008 is to be released by the end of January 2015.
