Likely you are seeing an IP alias, that's why you have two ip's on the same adapter.
Now, as to two adapters with same IP, one could be disconnected at the physical layer.
**EDIT again. You can assign an IP to the ETherChannel adapter, and then the parent adapter. But its not a good way to go about it. That actually looks like what is happening here. Or someone tried to remove a backup adapter from the EtherChannel and gave it the IP.
How can I see where the alias IP is configured?

To be honest, I'm not even sure where to begin with cleaning this up, or how far you want to go.
I can go very far
Could you shed some light on the parent Ether and child Ether?
And also with this, et is not used for IP address?

et is used for IEE 802.3

But I not yet find out where the alias IP (either 10.176.x.65 or 10.176.x.127) is configured.
I need to delete a TTY in my AIX 4.3 system. I have tried using the smit but everytime I try it, there is a message telling me that the device is in use and cannot be changed. How do I take the device "offline", so to speak, so that I can edit the settings and/or delete it.

Hi All,
How can I find out which is ETH5 on my AIX P5 system. I have about seven different NIC card on this. I did move the cable to each one but still I was not able to see the link light up when I did netstat -v
Any idea?
Thanks. (2 Replies)
I couldn't install my nic in solaris 10. I compiled and added

Dear All
I want tune my NIC's rps, rfs and xps value.
In my system I have two NIC (eth0, eth1) and I have a bond0 ( eth0, eth1).
Here is the question? Which device should I modify ?
eth0 and eth1? or just modify bond0 or modify all device (eth0, eth1, bond0)
Any advice is welcome.... (0 Replies)

Hello Admins,
My ask is how can I add two different subnet IPs to same box with two different gateways?
The issue is I can connect to the box when I am on ethernet LAN, but I am not able to connect to the same IP when I am on wifi. The server is RHEL 7 VM on vmware.
How can I get connected... (4 Replies)
I have Xubuntu 18.04 installed on my PC. I have created a 10G .img image file created by QEMU-IMG. I have installed inside of it Solaris 9 SPARC edition . If I try and mount the image file as a loop device (using sudo losetup /dev/loop0 /path-to-img-file) I can only mount it as read only.

Syntax
device ne0 at ibus? vector neintr
Description
The interface provides access to a 10 Mb/s Ethernet network through the Digital's Second Generation Ethernet Chip (SGEC) based controller.
The host's Internet address is specified at boot time with an SIOCSIFADDR ioctl. The interface employs the address resolution protocol
described in to map dynamically between Internet and Ethernet addresses on the local network.
The driver normally tries to use a trailer encapsulation to minimize copying data on input and output. This can be disabled for an inter-
face by setting the IFF_NOTRAILERS flag with an SIOCSIFFLAGS ioctl. Trailers are only used for packets destined for Internet hosts.
The SIOCSPHYSADDR ioctl can be used to change the physical address of the adapter and the SIOCRPHYSADDR ioctl can be used to read its phys-
ical address.
The SIOCADDMULTI and SIOCDELMULTI ioctls can be used to add or delete multicast addresses. The recognizes a maximum of 16 multicast
addresses.
The SIOCRDCTRS and SIOCRDZCTRS ioctls can be used to read or read and clear the Ethernet driver counters. The argument to these two ioctls
is a pointer to a counter structure, found in
The SIOCENABLBACK and SIOCDISABLBACK ioctls can be used to enable and disable the interface loopback mode respectively.
Diagnostics
The diagnostic error messages contain relevant information provided by the driver. For example,
ne%d: self test failed <reason lists>
Adapter did not pass the power-up self-test during autoconfiguration time.
ne%d: write CSR0 failed
The driver was unable to set the initial value for the adapter.
ne%d: couldn't allocate ......
The driver was unable to allocate memory for the internal data structures. ne%d: can't handle af%d
The interface was handed a message with addresses formated in an unsuitable address family, and the packet was dropped.
ne%d: memory error (MERR)
A host memory problem or a memory parity error has occurred.
ne%d: SIOCADDMULTI fail, multicast list full
Too many multicast requests have been made.
