auto port aggregation

sameerK — Tue, 08 Aug 2006 04:34:33 GMT

I am doing the fresh auto port aggregation configuration. While adding Lan0 to the APA I get the error message "protocol already logged on port 0". I suspect because I have already assigned Ip address to lan0.But that was mandatory at the time of os installation.Now how can I come out of this.

You probably need to unconfigure lan0 first.
Make sure you are working on the console to prevent connection problems.

An easy way to do this is to use SAM and perform the unconfigure action on the desired NIC.
You may also remove the configuration from /etc/rc.config.d/netconf file and unplump the interface.

there is no option to unconfigure in sam.for nic the options available are to modify,disable,delete..I cannot remove ip addresses as it is mandatory.

"Delete" will unconfigure the interface.

But make sure you do this on the console!

and if you want to "just try it" and have things revert on a reboot you can always do:

ifconfig unplumb

which will "unlog" the IP and ARP saps from the link and should make APA happy
