Hi all,
I have a 7204 router with an 18000K Hssi divided into many subinterfaces. IOS
12.2. Each subinterface bandwidth is using encap frame and is set for
1.544mbps in US and 2.048Mbps in Europe.
All sites will be placing voice calls. I have configured FRTS and
Fragmentation.
For QoS i have started to configure CBWFQ w/LLQ
I have created several policies based on the number of simultaneous calls per
site.
example:
1544K with 3 calls:
Policy-map WAN_EDGE_3
class REAL_TIME_VOICE
priority 192
class REAL_TIME_VIDEO
bandwidth 460
class INTERACTIVE
bandwidth 40
class MISSION_CRITICAL
bandwidth 200
class IMPORTANT3
bandwidth 300
police 300000 30000 conform-action transmit exceed-action transmit
violate-action set-dscp-transmit 0
class class-default
fair-queue
!
map-class frame-relay FRTS_1540K_3
frame-relay cir 1540000
frame-relay bc 15400
frame-relay be 0
frame-relay mincir 1540000
frame-relay fragment 1600
no frame-relay adaptive-shaping becn
service-policy output WAN_EDGE_3
!
int Hssi 2/0.14
frame-relay class FRTS_1540K_3
!
end
Now when i tried to create another policy for another interface, i recieved an
error as soon as i tried to set the bandwidth for the REAL_TIME_VIDEO to
460K.
error--
I/f Hssi2/0.14 DLCI 42 class REAL_TIME_VIDEO requested bandwidth 460 (kbps),
av
ailable only 448 (kbps)
now i understand that in periods of congestion this bandwidth is "nailed up"
but i doubt i am using 18megs at this point and the interface load is only
about 50/255. Besides, what does one policy have to do with the next?
i have researched and cant seem to find any solutions. If anyone can help i
would appreciate it.
thanks,
Kenneth Vargas
