[LARTC] Interfaces basic question

[Marius Corici]

[-- Attachment #1.1: Type: text/plain, Size: 506 bytes --]

I have a router with only one physical ethernet cable. I know it's stupid,
but it is the network I have to use for a demo.
I have in mind to construct an HTB class tree for some network limitations
for the outgoing traffic.

The question is: can i use the HTB class mechanism on 2 subinterfaces of the
same physical network card without any interference?

Please let me know as soon as possible. I need to know if I start working on
this or I have to change the hardware.

Thank you,

Marius

If you're talking about aliases like eth0:0 and eth0:1, I don't know, 
because I've never used them. It does work for other virtual interfaces 
like pppX (when it's really PPPoE going over some ethX interface).

If it doesn't work, why not just represent this structure in a single tree?
Like this:

HTB Qdisc eth0
|
\--- HTB root class (100mbit)
     |
     \--- HTB eth0:0 class (50mbit | 100mbit)
     |    |
     |    \--- The tree you wanted to put on eth0:0 goes here
     \--- HTB eth0:1 class (50mbit | 100mbit)
          |
          \--- The tree you wanted to put on eth0:1 goes here

HTH

Hey Marius,

u can only run the qdisc per interface, so if u have "tc qdisc add dev 
eth0 root handle 1: htb default 30" it will be applied to eth0:0 , 
eth0:1 aliases as well

U can shape on the one interface, your iptables commands must just be 
very specific.

hope it helps

J
