Cable Interface txload 255/255 although traffic is low

Hi,

I have a strange problem with cable interfaces - txload is 255/255 on all 6 interfaces. Upload speed is 7M maximum but download is good.
CMTS is 7246 with 3 MC88V cards.
I am completely stuck with this because upload speeds are very low. Here is a sh int output and configuration output.

Cable3/0 is up, line protocol is up
Hardware is UBR7200 CLC, address is 0021.1bbf.0c54 (bia 0021.1bbf.0c54)
MTU 1500 bytes, BW 50000 Kbit, DLY 1000 usec,
reliability 255/255, txload 255/255, rxload 26/255
Encapsulation MCNS, loopback not set
Keepalive set (10 sec)
ARP type: ARPA, ARP Timeout 04:00:00
Last input never, output never, output hang never
Last clearing of "show interface" counters never
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
Queueing strategy: fifo
Output queue: 0/40 (size/max)
30 second input rate 5169000 bits/sec, 3776 packets/sec
30 second output rate 61296000 bits/sec, 5788 packets/sec
18733796 packets input, 3745425194 bytes, 0 no buffer
Received 56266 broadcasts (4388 multicasts)
0 runts, 0 giants, 0 throttles
250 input errors, 31 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
55250288 packets output, 4104094771 bytes, 0 underruns
0 output errors, 0 collisions, 1 interface resets
0 output buffer failures, 0 output buffers swapped out

Dear muharem84,

Dear muharem84,

Can you please share this file from the disk2:
ubr7200p-jk9su2-mz.122-33.SCH6.bin
vatiacg dot kefo at gmail dot com

cmcaldas
possible modem file issue

can you post the modem file? could be simple like max burst and so on

Some suggestions and notes

Option 1 (more aggressive)

int cable 3/0
cable upstream 0 channel-width 6400000 3200000
cable upstream 0 minislot-size 2
cable upstream 0 modulation-profile 224 222
cable upstream 0 equalization-coefficient

---

Option 2 (less aggressive)

int cable 3/0
cable upstream 0 channel-width 3200000 1600000
cable upstream 0 minislot-size 4
cable upstream 0 modulation-profile 224 222
cable upstream 0 equalization-coefficient

---

Other misc notes I had on hand relating to tuning upload speeds :

Minislots :

For 6.4MHz width upstreams, set the minislots to 2 (rather than the default 1)
For 3.2MHz with upstreams, set the minislots to 4 (rather than the default 2)

Speed combinations observed during minislot testing :

3.2width 16qam = aggregate 8.9Mbps available
with default minislot-size 2 = peak modem speed 5.6Mbps
tweak minislot-size to 4 = peak modem speed 7.6Mbps

3.2width 64qam = aggregate 13.3Mbps available
with default minislot-size 2 = peak modem speed 8.5Mbps
tweak minislot-size to 4 = peak modem speed 11Mbps

6.4width 16qam = aggregate 17.8Mbps available
with default minislot-size 1 = peak modem speed 5.7Mbps
tweak minislot-size to 2 = peak modem speed 11Mbps

6.4width 64qam = aggregate 26.7Mbps available
with default minislot-size 1 = peak modem speed 8.6Mbps
tweak minislot-size to 2 = peak modem speed 16Mbps

Make sure your upstream service flow has a reasonably large burst configured :

burst 10000
max-concat-burst 10000

Interface :

cable default-phy-burst 0
cable map-advance dynamic 600 500

I have tried the options on

I have tried the options on cmts as you suggested. However the issue still persist. This is the config of modem, but I stil do not understand what it has to do with saturated link 255/255.
One of the cards also reboots itself. Here is the modem file:
