One of my troubleshooting techniques to verify if a customer is getting a multicast stream from a Nexus 7k was to run 'show ip mroute detail" & it would show me a 5gb/s bit rate which allowed me to confirm they were getting the feed. If it was a zero bit rate, I knew our upstream ACL was blocking the stream.
Now with our 5k's they show 0.00 bp/s even when the customer is successfully pulling the stream. Cisco documentation states: Cisco Nexus 5000 series devices do not support per packet counters. Hence the show ip mroute summary command does not show correct count of packets sent out. The packets per second (pps) count is shown as zero.
or
// The above output shows the number of packets sent as ‘0’ and the number of packets per second(pps)
also as 0. This is a known limitation in Cisco Nexus 5000 series devices.
My question is, how can I trust the switch to let me know if I'm passing full data on these multicast groups? Are there any other commands that are useful for this? It seems if I use 5k's I've lost half of my troubleshooting abilities.
