one question when setting up mutlicast

I am setting up multicast on a nexus switch, I am pretty confident I know what needs to be done, so my question is when setting this up will traffic be affected?

Hi @Isaac ,

When enabling Multicast PIM related commands, I do not expect disruption of Unicast traffic.

Cheers.

To config Multicast PIM - depends on sparse or sparse-dense mode ( do not recommend dense mode at all)

you are ok to do.

unlike IOS, you need enable feature before you config PIM

wanted to provide an update: the configuration worked here is some back ground information. The paging server is on the same vlan as the phones, with that being said all I needed to do was find an IP address I could reserve for ip igmp snooping querier. the complete commands are:

conf t

vlan configuration 110

ip igmp snooping querier (IP address in same subnet)

applied this to both nexus switches and worked.
