Testing an Inline Bypass Interface Installation
Managed devices with bypass interfaces provide the ability to maintain network connectivity even when
the device is powered off or inoperative. It is important to ensure that you properly install these devices
and quantify any latency introduced by their installation.
Your switch's spanning tree discovery protocol can cause a 30-second traffic delay. Cisco recommends
Note
that you disable the spanning tree during the following procedure.
The following procedure, applicable only to copper interfaces, describes how to test the installation and
ping latency of an inline bypass interface. You will need to connect to the network to run ping tests and
connect to the managed device console.
Before You Begin
•
To test a device with inline bypass interface installation:
Set all interfaces on the switch, the firewall, and the device sensing interfaces to auto-negotiate.
Step 1
Firepower System devices require auto-negotiate when using auto-MDIX on the device.
Note
Power off the device and disconnect all network cables.
Step 2
Reconnect the device and ensure you have the proper network connections. Check cabling instructions
for crossover versus straight-through from the device to the switches and firewalls, see
Deployments on Copper Interfaces, page
Step 3 With the device powered off, ensure that you can ping from the firewall through the device to the switch.
If the ping fails, correct the network cabling.
Run a continuous ping until you complete step 9.
Step 4
Power the device back on.
Step 5
Using your keyboard/monitor or serial connection, log into the device using an account with
Step 6
Administrator privileges. The password is the same as the password for the device's web interface.
The prompt for the device appears.
Shut down the device by typing
Step 7
You can also shut down the device using its web interface; see the Managing Devices chapter in the
Firepower Management Center Configuration Guide. As most devices power off, they emit an audible
click sound. The click is the sound of relays switching and the device going into hardware bypass.
Step 8 Wait 30 seconds.

If you are deploying a device with bypass interfaces, test that you properly installed these devices;
see Testing an Inline Bypass Interface Installation, page
Ensure that the interface set type for the Firepower device is configured for inline bypass mode.
See Configuring Inline Sets in the Firepower Management Center Configuration Guide for
instructions on configuring an interface set for inline bypass mode.
