I think it is the command: "show traffic-shaping queue"

Subject: CQ/PQ on subinterface/PVC
> Hello all,

> I've been trying to understand how queueing on subinterfaces works and
came to the following conclusion: if shaping is not enabled then there is no
per-subinterface queueing. Cisco DQOS book chapter 4 section "Queueing on
Interfaces versus Subinterfaces and Virtual Circuits" page 245 says:

> IOS also supports queueing on subinterfaces and individual VCs when
traffic shaping is also enabled"

> Therefore when meeting a task which asks for Custom Queueing to be enabled
on single Frame Relay PVC on multipoint interface I think that the following
is an invalid config:

> queue-list 1 queue 1 protocol ip tcp telnet
> queue-list 1 queue 2 protocol ip tcp ftp
> queue-list 1 default 3
> queue-list 1 queue 1 byte-limit 3000
> queue-list 1 queue 2 byte-limit 3000
> queue-list 1 queue 3 byte-limit 1500

> ip address 10.10.10.1 255.255.255.0
> frame-relay map ip 10.10.10.2 102 broadcast
> frame-relay map ip 10.10.10.3 103 broadcast

> I could not find a command which confirms that Custom Queueing is enabled
on PVC 102. "show queueing" does NOT take subinterface/DLCI as parameter.
> If we have FRTS enabled on main interface S0/0 then "sh traffic-shape"
shows us that CQ is indeed enabled on PVC 102.

> Inference - if asked to have CQ/PQ enabled on a "link between router X and
router Y" then check whether that router pair is connected via multipoint
interface(s) and enable Traffic Shaping on main interface (watch for default
traffic shaping parameters here) together with building a queue-list and
assigning it to subinterface/PVC.
