Hi,
I would like to setup the following:
Internet ------------ 5
--------------------------------eth0---| linuxbox |---eth1.6----\
------------ 7 |
|
----------------------- |
| Cisco catalist 2924 | |
--|---|---|---------|-- |
| | Vlan7 \-------------------------------------------/
| Vlan6
Vlan5
eth1 has 802.1q VLAN tagging enabeled, and 3 vlan's configured.
Each vlan has it's own interface on the linux box and an own private
subnet. Now would i like to do bandwidth division, and allowing vlan's to
borrow bandwidth from each other.
I have put the three vlan interfaces into the same root class.
The configuration works fine exept that each vlan seems to have the whole
"128K" of its own, each vlan can download at 128K at the same time.
It seems to me that each interface is in a class of its own. How can i
correct this ???
I use the following script to setup things.
Vlan setup:
------
#!/bin/sh
# add vlan's to eth1
vlanctl add eth1 5
vlanctl add eth1 6
vlanctl add eth1 7
# set eth1 up
ifconfig eth1 up
# run ifconfig on vlan's
ifconfig eth1.5 192.168.15.254 netmask 255.255.255.0
ifconfig eth1.6 192.168.16.254 netmask 255.255.255.0
ifconfig eth1.7 192.168.17.254 netmask 255.255.255.0
# turn on forwarding and masquerading:
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
------------------
CBQ setup:
------
#!/bin/sh
# Bandwith division
# Put all interfaces in root queueing discipline:
tc qdisc add dev eth1.5 root handle 10: cbq bandwidth 100Mbit avpkt 1000
tc qdisc add dev eth1.6 root handle 10: cbq bandwidth 100Mbit avpkt 1000
tc qdisc add dev eth1.7 root handle 10: cbq bandwidth 100Mbit avpkt 1000
# Genereate root classes and put all vlans in it
tc class add dev eth1.5 parent 10:0 classid 10:1 cbq bandwidth 100Mbit
rate 128Kbit allot 1514 weight 10Mbit prio 5 maxburst 0 avpkt 1000 bounded
tc class add dev eth1.6 parent 10:0 classid 10:1 cbq bandwidth 100Mbit
rate 128Kbit allot 1514 weight 10Mbit prio 5 maxburst 0 avpkt 1000 bounded
tc class add dev eth1.7 parent 10:0 classid 10:1 cbq bandwidth 100Mbit
rate 128Kbit allot 1514 weight 10Mbit prio 5 maxburst 0 avpkt 1000 bounded
# Generate a class for each vlan
tc class add dev eth1.5 parent 10:1 classid 10:100 cbq bandwidth 100Mbit
rate 64Kbit allot 1514 weight 10Mbit prio 5 maxburst 0 avpkt 1000
tc class add dev eth1.6 parent 10:1 classid 10:200 cbq bandwidth 100Mbit
rate 64Kbit allot 1514 weight 10Mbit prio 5 maxburst 0 avpkt 1000
tc class add dev eth1.7 parent 10:1 classid 10:300 cbq bandwidth 100Mbit
rate 64Kbit allot 1514 weight 10Mbit prio 5 maxburst 0 avpkt 1000
# Set queueing Method
tc qdisc add dev eth1.5 parent 10:100 sfq quantum 1514b perturb 15
tc qdisc add dev eth1.6 parent 10:200 sfq quantum 1514b perturb 15
tc qdisc add dev eth1.7 parent 10:300 sfq quantum 1514b perturb 15
# Set filters to Apply Queueing
tc filter add dev eth1.5 parent 10:0 protocol ip prio 100 u32 match ip dst
192.168.15.0/24 flowid 10:100
tc filter add dev eth1.6 parent 10:0 protocol ip prio 100 u32 match ip dst
192.168.16.0/24 flowid 10:200
tc filter add dev eth1.7 parent 10:0 protocol ip prio 100 u32 match ip dst
192.168.17.0/24 flowid 10:300
