Top Forums UNIX for Advanced & Expert Users Changing single path NIC to a teamed connection in same subnet Post 303038879 by Neo on Monday 16th of September 2019 09:24:42 AM

What happens when you look at the arp tables, before and after?

On ethernet, as you know, the actual LAN routing is done by MAC address; so when we change IP address, we need to flush / rebuild the arp table (on both ends), generally speaking.

If we change an IP address and do not flush the arp table, there will often be an incorrect IP address <---> MAC address in the arp table and this can cause LAN routing snafus.

PS: I'm writing this based on knowledge from decades ago, off the top of my head, and have not done any research on arp in a long time.

NAME
sndconfig - configure sound card for use with Linux kernel modules SYNOPSIS
sndconfig {--help,--noprobe,--noautoconfig} DESCRIPTION
sndconfig sets up the necessary configuration files to use a sound card on a Red Hat system. If PnP support is compiled in, by default snd- config will do an initial probe for PnP sound cards using the pnpdump utility. If the --noprobe option is given this step will be skipped. The user will be notified if any cards were found. Otherwise the user must pick the card type from a menu. Then the user must choose the I/O port, IRQ, and DMA settings for the sound card. These must be known ahead of time and depend upon the jumper settings of the sound card. For PnP cards, the program will determine settings for the card; if the --noautoconfig option is given the user can choose the val- ues which will be programmed into the PnP device. There is no guarantee that the values entered do not conflict with an existing non-PnP or PnP device. The user must make sure these types of conflicts do not occur. OPTIONS --help Print a usage message on standard output and exit successfully. --noprobe No probe will be made for PnP cards, and the PnP configuration files will not be changed. --noautoconfig No autoconfiguration of PnP cards will be done; the user will be prompted for settings. FILES
