Solaris Logic to transmit traffic to physical interfaces ( eg ce0 and ce1)
Just wanted to understand what is the logic being used by Solaris(kernel) to transmit data/traffic on physical interfaces.
I have seen most of the time traffic is being sent to interface ce0 and sometime to ce1.
I have removed ip address from below command for some reason.
Trying to figured out the logic/algorithm used to send traffic/data. i have gone through couple of document and understand, when system transmit a packet, it must locate the "BEST" interface over which to sent it.
but not so cleared about the algorithm or logic behind,since most of the time it uses ce0 and sometimes it use ce1 how?
Your early response will be appreciated with detailed explanation about this logic.
Thanks

There are basically two possible situations: network interfaces attached to different networks and network interfaces attached to the same network.
If the network interfaces are attached to different networks, the routing table controls what is sent using which interface. The contents of the routing table may or may not be further controlled by routing protocols (RIP, OSPF, EGP, ...). This is like it is in every IP-host.
If there are several interfaces pointing into one network, per default Solaris employs all the interfaces using a round-robin algorithm, if i remember correctly.
It is also possible to configure several interfaces into the same network to form aggregated links: etherchannels, configured for either additional bandwidth or high-availability (or both), etc..
Hi All
Kindly let me know how can I move Solaris 10 OS running update 10 on physical machine to another machine solaris zone running Solaris 10 update 11 (2 Replies)
can we configure the ce0 and ce1 interface as ce4000 and ce5000 in solaris 9
I have a server configured similar way.. I need to setup another two server in such configuration find the sample output from working server.

Hello,
I have a machine with Solaris 8, and it has multiple interfaces that are connected to the same network which means they all have metric 0 (1 hop) to the default gateway.
assume:
* e1000g0: 10.1.1.70
* e1000g2: 10.1.1.72
* e1000g4: 10.1.1.74
* e1000g5: 10.1.1.76

I have a Linux box with 3 ethernet cards:
- eth0 - connected to internet (dhcp)
- eth1 - 192.168.0.1 connected to embedded device1
- eth2 - 192.168.0.1 also connected to embedded device2
(both eth1/eth2 have to be in identical, though separate, private networks).
Also, on eth0 I have two... (1 Reply)
hi,
Can I listdown all available net interfaces on my system like SF4800 or Netra440.
I know there are 4 port physically present but I can't see or list them using either

may be I'm missing switched on these or may some other command... (8 Replies)
Hi Community,
I've a problem with IPMP: I have 2 physical interfaces, 1 "physical IP" and 1 VirtualIP.
My question is:
is it possible to have IPMP configuring 2 physical interfaces with the same "physical" IP Address?
for example:
ce0 10.10.10.10
ce5 10.10.10.10
and

Hi,
I am trying to configure an ip address, netmask, and default gateway on my solaris machine. For example, in Linux I would do the following command:
#ifconfig eth0 xx.xx.xx.xx netmask 255.0.0.0
#add route or route add default xxx.xxx.xxx.xxx
In Solaris 10, I believe the commands are... (7 Replies)
