Hi Dave,
The issue I believe is that the trust boundary device feature is not supported until release 12.2(33)SXI1 or later. Below is an extract taken from the 12.2(SX) Configuration guide:-
Configuring Trusted Boundary with Cisco Device Verification
Release 12.2(33)SXI1 and later releases support the trusted boundary with Cisco device verification feature, which configures Ethernet LAN ports to use CDP to detect whether or not a Cisco IP phone is attached to the port.
•
If CDP detects a Cisco IP phone, QoS applies a configured mls qos trust dscp, mls qos trust ip-precedence, or mls qos trust cos interface command.
•If CDP does not detect a Cisco IP phone, QoS ignores any configured nondefault trust state.
To configure trusted boundary with Cisco device verification, perform this task:
Command | Purpose | |
|---|---|---|
Step 1 | Router(config)# interface {{type1 slot/port} | {port-channelnumber}} | Selects the interface to configure. |
Step 2 | Router(config-if)# mls qos trust device cisco-phone | Configures trusted boundary with Cisco device verification. |
Step 3 | Router(config-if)# end | Exits configuration mode. |
Step 4 | Router# show queueing interface type1 slot/port | include [Tt]rust | Verifies the configuration. |
1 type = fastethernet, gigabitethernet, tengigabitethernet. |
When configuring trusted boundary with Cisco device verification, note the following information:
•CDP must be enabled on the port to use trusted boundary with Cisco device verification

Allan.
