Command History
Usage Guidelines The CTS Layer 3 Transport feature permits Layer 2 SGT-tagged traffic from TrustSec-enabled network
segments to be transported over non-TrustSec network segments by the application and removal of a
Layer 3 encapsulation at specified CTS Layer 3 gateways. A traffic policy is an access list that lists all
the TrustSec-enabled subnets and their corresponding gateway addresses. An exception policy is an
access list that lists the traffic on which not to apply the CTS Layer 3 Transport encapsulation. For
example, the RADIUS packets used to acquire the policy should be sent in the clear.
Specify the traffic and exception policies with the cts policy layer3 {ipv4 | ipv6} traffic access_list and
the cts policy layer3 {ipv4 | ipv6} exception access_list global configuration commands. Apply the
traffic and exception policies on the CTS L3 gateway interface with the cts layer3 {ipv4 | ipv6} policy
interface configuration command. Enable the CTS L3 gateway interface with the
cts layer3 {ipv4 | ipv6} trustsec forwarding interface configuration command.
ipv4 exception access_list (Optional). Specifies an already defined ACL defining exceptions to the
IPv4 L3 traffic policy.
ipv4 traffic access_list Specifies an already defined ACL listing the IPv4 Trustsec-enabled
subnets and gateways.
ipv6 exception access_list (Optional). Specifies an already defined ACL defining exceptions to the
IPv6 L3 traffic policy.
