Article ID: KB34752 KB Last Updated: 01 Aug 2019Version: 1.0
Summary:

On QFX10K (QFX10002, QFX10008, QFX10016), testing the connectivity between the REs and FPC might be used as a health check step. It helps to verify that the Routing Engines are able to reach/communicate with the FPCs. 

Solution:

To test connectivity from the RE to all FPCs, issue the following command 

‚Äčtest chassis routing-engine fpc-connectivity re-slot <> fpc all

Example:

root@qfx10002-re0> test chassis routing-engine fpc-connectivity re-slot 0 fpc all

FPC 0 is reachable from RE slot 0
FPC 1 is reachable from RE slot 0
FPC 6 is reachable from RE slot 0
FPC 7 is not reachable from RE slot 0

root@qfx10002-re0> test chassis routing-engine fpc-connectivity re-slot 1 fpc all

FPC 0 is reachable from RE slot 1
FPC 1 is reachable from RE slot 1
FPC 6 is reachable from RE slot 1
FPC 7 is not reachable from RE slot 1

You can also test the connectivity from a specific RE to a specific FPC by issuing the following command

‚Äčtest chassis routing-engine fpc-connectivity re-slot <> fpc fpc-slot <>

Example:

root@qfx10002-re0> test chassis routing-engine fpc-connectivity re-slot 0 fpc fpc-slot 0
FPC 0 is reachable from RE slot 0
