We have just configured a IPMP group with following /etc/hostname.xsvnicx files
-bash-3.00# cat /etc/hostname.xsvnic53
190.100.15.1 netmask 255.255.255.0 group hari1 up
-bash-3.00# cat /etc/hostname.xsvnic57
group hari1 standby up
-bash-3.00#
Now we perform following steps
1. unplumb the primary nic xsvnic53. Fail over happens to secondary xsvnic57,
and xsvnic57:1 gets created and traffic goes on via secondary
2. Now we plumb the primary nic xsvnic53 again and IPMP Primary gets
configured afresh grouping with the old secondary.
3. Now if we do a link down on secondary xsvnic57, the fail back happens to
primary xsvnic53 with floater interfaces (xsvnic53:1 and xsvnic53:2) getting
configured.
4. every time we do a unplumb and plumb on primary, one extra floater interface
gets configured (piles up like xsvnic53:1 :2 :3 and :4).
5. Eventually after 4 such floater interfaces [xsvnic53:1,:2 :3 & :4] configs,
the pings stall and hangs as shown under
-bash-3.00# ifconfig -a
