Verifying the SGSN Direct Tunnel Configuration
Enabling the setup of a GTP-U direct tunnel on the SGSN is not a straight forward task. It is controlled by an operator
policy with related configuration in multiple components. Each of these component configurations must be checked to
ensure that the direct tunnel configuration has been completed. You need to begin with the operator policy itself.
Verifying the Operator Policy Configuration
For the feature to be enabled, it must be allowed in the call-control profile and the call-control profile must be associated
with an operator policy. As well, either an APN profile or an IMEI profile must have been created/configured and
associated with the same operator policy. Use the following command to display and verify the operator policy and the
association of the required profiles:
show operator-policy full name
<policy_name>
The output of this command displays profiles associated with the operator policy.
[local]asr5x00# show operator-policy full name
