3 In the MAC Statistics section (for ETEP PEPs), note the values in the Transmit and Receive packet
entries for the Local and Remote interfaces (Local Port and Remote Port).
● If packets are being received on the Local interface and transmitted on the Remote interface,
traffic is being passed in the outbound direction. If packets are not being transmitted on the
Remote interface, traffic is not being passed.
● If packets are being received on the Remote interface and transmitted on the Local interface,
traffic is passing in the inbound direction. If packets are not being transmitted on the Local
interface, traffic is not being passed.
4 In the IPSec Encryption Statistics section of the Statistics view, note the values in Inbound and
Outbound traffic directions.
● If inbound traffic is being received, but the Inbound (decryption completed) count is zero, traffic
is not being decrypted.
● If outbound traffic is being transmitted, but the Outbound (encryption completed) count is zero,
traffic is being sent in the clear.
With ETEP PEPs, you can only view decryption completed and encryption completed counts. You
cannot view the decryption and encryption attempted counts. However, you can click View > Status
to see discard counts.
Solving Policy Problems
If you have confirmed that the PEP is not encrypting traffic, the priority settings for your policies could
be incorrect. Each PEP implements policies based on the priority and data filtering criteria set on each
policy. You can also experience policy problems if you restore a previous file system on a PEP and
inadvertently restore policies or certificates that have expired.
The following topics can help you identify and resolve policy problems:
● “Viewing Policies on a PEP” on page 246
● “Placing PEPs in Bypass Mode” on page 246
● “Allowing Local Site Exceptions to Distributed Key Policies” on page 247
● “Expired Policies” on page 247
● “Cannot Add a Network Set to a Policy” on page 248
● “Packet Fragments are Discarded in Point-to-Point Port-based Policies” on page 248
Viewing Policies on a PEP
For ETEP PEPs, export the SPD to view the policies that are in effect (for more information, see
“Exporting SAD and SPD Files” on page 232).
Look at the priority and data filtering criteria for each policy implemented on the PEP. Look for clear
policies at a higher priority than an encrypt policy for the same data that will override the encrypt policy.
If you identify such a policy, change the priority of the policy in ETPM
and redeploy your policies.
Placing PEPs in Bypass Mode
For troubleshooting policy problems, it can be helpful to place the PEPs in bypass mode to verify that
traffic can pass in the clear.
