Regarding the configuration documented on CCO, the encapsulation dot1Q 1 native (or any VLAN with the keyword 'native') on the subinterfaces isn't allowed because the native VLAN traffic doesn't get its frames tagged, and tagging is the mechanism whereby IOS correlates the traffic to the NME-522 for any interfaces besides the service-module ip interface).

While not actually required for the host validation, the static routes have to exist to get traffic to CUSP over the router's backplane.

At this point you should be able to ping each of these IP's from your network.  Note: the default gateway for all traffic is still the service-module ip default-gateway.  Without the NME side configuration, CUSP will not allow you to configure sip listen for those IP addresses.

Here is a working interface configuration (router side) that the module is able to boot up with:


interface Loopback1

Regarding the configuration documented on CCO, the encapsulation dot1Q 1 native (or any VLAN with the keyword 'native') on the subinterfaces isn't allowed because the native VLAN traffic doesn't get its frames tagged, and tagging is the mechanism whereby IOS correlates the traffic to the NME-522 for any interfaces besides the service-module ip interface). While not actually required for the host validation, the static routes have to exist to get traffic to CUSP over the router's backplane.

We're not done yet! Once the router knows how to get the traffic to the NME, the NME itself has to know to be listening on said interfaces. Here's the matching configuration for the NME:


interface GigabitEthernet 0.1
 end interface


interface GigabitEthernet 0.11
 ip address 10.15.211.1 255.255.255.252
 end interface


interface GigabitEthernet 0.12
 ip address 10.15.212.1 255.255.255.252
 end interface


interface GigabitEthernet 0.13
 ip address 10.15.213.1 255.255.255.252
 end interface

At this point you should be able to ping each of these IP's from your network. Note: the default gateway for all traffic is still the service-module ip default-gateway. Without the NME side configuration, CUSP will not allow you to configure sip listen for those IP addresses.
