My approach would be to shape the sub-interface to a given level first, then
apply CBWFQ under that, identifying any specific traffic after the shaped
rate has been set. You can shape to 100% if you don't know the bandwidth
allocation as follows:
policy-map parent
class class-default
shape average percent 100
service-policy child
policy-map child
class class1
bandwidth percent 20
int serial 1.1
service-policy-out parent
If you apply this configu, you get the following output which shows the
overall rate for the sub-interface and 20% of the bandwidth guaranteed for
the traffic you want.
Service-policy output: parent
Class-map: class-default (match-any)
0 packets, 0 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: any
Traffic Shaping
Target/Average Byte Sustain Excess Interval Increment
Rate Limit bits/int bits/int (ms) (bytes)
100 (%) 0 (ms) 0 (ms)
1544000/1544000 9650 38600 38600 25 4825
Adapt Queue Packets Bytes Packets Bytes Shaping
Active Depth Delayed Delayed Active
- 0 0 0 0 0 no
Service-policy : child
Class-map: class1 (match-all)
0 packets, 0 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: access-group name FORS1.1
Queueing
Output Queue: Conversation 73
Bandwidth 20 (%)
Bandwidth 308 (kbps) Max Threshold 64 (packets)
(pkts matched/bytes matched) 0/0
(depth/total drops/no-buffer drops) 0/0/0
Class-map: class-default (match-any)
0 packets, 0 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: any
Does this help?
