Here is a table of the ports that are used for chassis cluster control link and management ports on Branch SRX devices.
The quoted ports are the 'stand alone' non clustered port names (not node1's port names once clustered). In a SRX cluster the PIM slots on node1 start at the last PIM slot of node0 + 1. For example, a SRX240 cluster's node1 starts at PIM 5. It's control link port is effectively ge-5/0/1).
| Model | FXP0 (Management) | FXP1 (Control Link) |
| SRX100 | fe-0/0/6 | fe-0/0/7 |
| SRX210 | fe-0/0/6 | fe-0/0/7 |
| SRX220 | ge-0/0/6 (> 11.0) | ge-0/0/7 |
| SRX240 | ge-0/0/0 | ge-0/0/1 |
| SRX550 | ge-0/0/0 | ge-0/0/1 |
| SRX650 | ge-0/0/0 | ge-0/0/1 |
*fab0 and fab1 interfaces (Data Link) are always configurable, e.g.:
- set interfaces fab0 fabric-options member-interfaces ge-0/0/2
- set interfaces fab1 fabric-options member-interfaces ge-5/0/2
