Introduction

This document describes a problem where authentication to a Network Module Engine (NME) appears to fail.

Trying to session into a NME-WAE-502 from the router shows a login prompt, but login with WAAS (Wide Area Application Services) credentials fails as follows (in the example the NME-WAE is in slot 1):

router# service-module integrated-Service-Engine 1/0 session

Trying 192.0.2.2, 2066 ... Open

User Access Verification

Username: admin

Password:

% Authentication failed

Problem

If you're already entering the correct WAAS credentials, this issue could be due to authentication configuration on the router.  Observe the login banner does NOT have "Cisco Wide Area Application Services Engine Console", check if the router has AAA (Authentication, Authorization, Accounting) configured, see below sample router configuration.

router# show run | inc aaa

aaa new-model

aaa authentication login default group tacacs+ enable

In this case you first need to login using the router credentails, press <ENTER> and only then a second login prompt will be shown were you can login using the WAAS credentials.

Solution

The login prompt shown is coming from the router, not the NME-WAE. You first need to give the router credentials, then press <ENTER> and only then the actual WAAS login prompt will appear:

router# service-module integrated-Service-Engine 1/0 session

Trying 192.0.2.2, 2066 ... Open

User Access Verification

Username: <-- router-username

Password: <-- router-password

<-- Hit <ENTER>

Cisco Wide Area Application Services Engine Console

Username: <-- waas-username

Password: <-- waas-password

Device is configured with a (well known) default username/password for ease

of initial configuration.This default username/password should be changed in

order to avoid unwanted access to the device.

System Initialization Finished.

WAAS#

At the login prompt after seeing the Cisco Wide Area Application Services Engine Console line normal WAAS credentials can be used (defaults: username: admin / password: default).
