I am not aware of any implementation or plans to implement an IPv6 equivalent to the ARP monitor (arp_interval, et al) in bonding. If the blade switches support a trunk failover system (wherein the switch will drop carrier on internal facing ports when carrier is lost on an external port), it is possible to implement approximately equivalent functionality using trunk failover and the bonding mii monitor (miimon). -J --- -Jay Vosburgh, IBM Linux Technology Center, fubar@us.ibm.com
