Imperva MX server only displays one gateway Imperva gateway running on 2 different Crossbeam chassis are registered and running, however only one gateway will show up on the GUI
The MX server will register the gateways based on the eth0 MAC address of the vaps and if the MAC address is the same it will simply replace the current gateway with the new gateway being registered.The last gateway to be registered will show in the GUI, replacing the previous gateway
Chassis A system-identifier 101 vap-group dbfw Imperva is installed ACTIVE on slot 5

Chassis B system-identifier 101 vap-group imp Imperva is installed ACTIVE on slot 5
ifconfig output for imp_1 imp_1 (chassisB): ~# ifconfig eth0 eth0 Link encap:Ethernet HWaddr 00:03:D2:00:65:05 inet addr:10.47.101.107 Bcast:10.47.101.255 Mask:255.255.252.0
To prevent this issue from happening and also being able to run Imperva on any slot within the chassis, change the system identifier to be unique between the 2 chassis.
Modify the ap-list on one of the chassis such that Imperva loads on a different slot/APM
