To apply QoS policies to an ISAKMP profile, perform the following steps.

To verify your IPsec and QoS sessions, perform the following steps. The show commands can be used in any order or independent of each other.

In the following example, a specific QoS policy is applied to two groups of remote users. Two ISAKMP profiles are configured so that upon initial connection via IKE, remote users are mapped to a specific profile. From that profile, all IPsec SAs that have been created for that remote will be marked with the specific QoS group. As traffic leaves the outbound interface, the QoS service will map the IPsec set QoS group with the QoS group that is specified in the class maps that comprise the service policy that is applied on that outbound interface.

The following output shows that QoS group "2" has been applied to the ISAKMP profile "blue" and that QoS group "3" has been applied to the ISAKMP profile "yellow":

Router# show crypto isakmp profile
ISAKMP PROFILE blue
   Identities matched are:
    group blue
   QoS Group 2 is applied
ISAKMP PROFILE yellow
   Identities matched are:
    ip-address 10.0.0.13 255.255.255.255
    group yellow
   QoS Group 3 is applied

The following output shows that the QoS group has been applied to a particular pair of IPsec SAs:
