[Linux-cluster] RH Cluster issue-Network Failover not happening

[Rajagopal Swaminathan]

namo namaH,
(Whatever that is to be respected-adored, that is respected adored)

Apologies for top posting, but this incident compels me.

Please, did you follow my earlier suggestion as many new "manged" Cisco
switches need to have their multicasting  tuned on _manually_ using some
commands (_incantations_)

and I would feel compelled _not_to reply to your future post if you have not
responded to _My_  posts.


I am an Indian living in India and being paid far less less than what you
are paid in Gulf, so I do not have a compelling reason to reply or educate
you if you are not being communicative.
