[openib-general] ifconfig ib0 down and then up vis a vis IP connectivity

[Hal Rosenstock]

Hi,

What is the ARP timeout in Linux ?

If I down and then up the ib0 interface, there is some delay before
connectivity is restored despite the fact that it is successfully
(re)attached to the multicast groups and that all the QPNs seem to be
the same. After some time period, connectivity is restored. Any idea on
what is different ? It seems like it is an ARP cache issue.

Thanks.
