Re: MULTICAST

Morning Jack. Morning team.

Jack - I read this the same as Joe A. You have a 512 link and when you send
mcast plus your other traffic, it results in over 90% link utilization.

Now ... you may see 90% link utilization, however ... traffic is bursty and
the bursts occur at a msec time interval. How many bursts, buffering,
jitter, and potential drops are you seeing or experiencing? Unfortunately
you will not see all of this via SNMP, or the show commands. Gaining
visibility into these will often require external devices to monitor and
record.

You might need to consider upgrading these links if this mcast is important.
  QoS and compression might help some as well ... and before doing so, you
would want to perform a survey and evaluate the affect this will have on the
traffic / user experience.

HTH,

Andrew
