Hi,
I have here two Nexus7k chassis and I want to make use of the CFS feature. As far as I understood, it is using multicast for synchronising the configuration on both chassis.
Both SUP management interfaces are connected to an old 3550 rackswitch and provide out-of-band management.
Q1: Do I now additionally need to configure PIM or IGMP on the rackswitch in order to get CFS working properly?
Q2: Shouldn't I see both peers on the output below if everything is working right?
SwitchB# sh cfs peers name ntp
Scope : Physical-fc-ip
