Re: SRX3600 Fabric Link (fab0/fab1) over Cisco Switch

Hello,

As per the documentation ports Gi1/0/37 and Gi1/0/38 should not have LACP i.e. the setting on the ports should be "mode on".

It is not possible to use LACP on fab interfaces in chassis cluster of SRX since dual fabric interfaces have different operations to perform in chassis cluster. Please refer the following document to understand dual fabric links on SRX.
