M20 CoS Problems
M20 CoS Problems
In slot 0 I have an EFPC. Inside that slot I have 4 pics, 2 channelized DS3 cards (non-IQ), 1 MLPPP card, 1 GigE card. I'm trying to get CoS running on all those interfaces, but I'm stuck.
On the GigE and MLPPP interfaces, it looks like its working perfectly, but on the channelized ds3 cards, it's not working.
Since the non-IQ version of the channelized DS3 card doesn't show queue stats its hard to really tell what's going on.
From what I read, the non-IQ version of this card should have no problem doing CoS inside an EFPC, but I can't get it to work. If I do a show interfaces extensive on one of the interfaces, it gives me mixed results. First it shows me the following right under the the T1/DS3 error info
B/W WRR Packets Bytes Drops Errors
Queue0 95 95 1889 299867 0 0
Queue1 5 5 736 8832 0 0
Which are the default queues logging traffic on this interaface, but only a few more lines down it shows
% bps % bytes
0 best-effort 85 1305600 90 0 low none
1 expedited-forwarding 10 153600 5 0 strict-high none
3 network-control 5 76800 5 0 low none
Which are the queues I created.
When the interface is passing any more then 100k worth of traffic, the voip gateway on the other side starts logging a lot of jitter causing lost packets and high delays.
I don't understand why this is happening and I've been tearing my hair out trying to figure it out. I've hired 2 consultants who couldn't tell me why it wasn't working, I contacted JTAC but since I don't have a support contract, I can't get any type of priority support (they did open a "courtesy" ticket, but they've been less then responsive) and they won't sell me one because the M20 went EOL on Dec 31 2007, shortly after we bought the thing.
I would appreciate hearing from anyone who's had this configuration before, or anyone who can point me in the right direction.
