LACP Etherchannel with HP Blade center Flex10 switch

Unanswered Question

Hi all,

I've got an HP blade center with Flex10 switch connecting to a 6509 running CAT OS via two separate LACP etherchannel groups, and each group has two 1GB links to the 6509. I am having some strange layer 2 connectivity issues with the blade server on the HP blade center. From the HP blade server for some reason I am not able to ping another server (a regular server) and both servers (regular server and the HP blade server) are connected to the same 6509 module and are on the same VLAN. And from the sniffer trace I learned that the issue has something to do with ARP. It seems like there is no ARP response when I try to ping. So I was able to come up with a workaround for the time being by manually add static ARP entry on both servers (HP blade server and the regular server). At this point I suspect it's something with the LACP eitherchannel link between the 6509 and HP blade center but I don't know what would cause the issue.

Any help/inputs/suggestions is high appreciated !!!! Thanks in advance !!!


I have this problem too.
