Greetings!
I've tried to use ALTQ and start as described on "ALTQ Tips" document by
Kenjiro Cho. Unfortunately, the altqstat shows me the floolowing out:
altqstat: fifoq on interface tlp0
q_len:0 q_limit:50 period:0
xmit:0 pkts (0 bytes) drop:0 pkts (0 bytes)
throughput: 0bps
q_len:31 q_limit:50 period:0
xmit:0 pkts (0 bytes) drop:0 pkts (0 bytes)
throughput: 0bps
q_len:37 q_limit:50 period:0
xmit:0 pkts (0 bytes) drop:0 pkts (0 bytes)
throughput: 0bps
q_len:37 q_limit:50 period:0
xmit:0 pkts (0 bytes) drop:0 pkts (0 bytes)
throughput: 0bps
q_len:29 q_limit:50 period:0
xmit:0 pkts (0 bytes) drop:0 pkts (0 bytes)
throughput: 0bps
q_len:0 q_limit:50 period:0
xmit:0 pkts (0 bytes) drop:0 pkts (0 bytes)
throughput: 0bps
which is looks strange for me (xmit 0 pkts, etc.)
At the time of altqstat is running the netperf was used to create
the some network flow:
TCP STREAM TEST to 192.168.0.7 : histogram
Recv Send Send
Socket Socket Message Elapsed
Size Size Size Time Throughput
bytes bytes bytes secs. 10^6bits/sec
57344 57344 8192 20.02 28.93
The altq.conf contains the following line only:
interface tlp0 bandwidth 30M fifoq
and kernel config contains some aproppriate options:
options ALTQ # Alternate Queueing
options ALTQ_RED # ALTQ Random Early Detection
options ALTQ_RIO # ALTQ RED with In/Out support
options ALTQ_FIFOQ # ALTQ FIFO Quieueing
options ALTQ_CBQ # ALTQ Class-Bassed Queueing
options ALTQ_HFSC # ALTQ Hierarhical Fair Service Curve
options ALTQ_PRIQ # ALTQ Priority Queueing
options ALTQ_WFQ # ALTQ Weighted Fair Queueing
options ALTQ_IPSEC # ALTQ IPSec support
Is this a real problem? Note, the throughput was really decreased to
30Mb/sec (about 93Mbit/sec without ALTQ), but altqstat still show me
just nothing, but qlen only. System - NetBSD 1.6ZF.
Thanks for your time.
