** PLS HELP ** Multicast GDA Deletion after STP change occurs
Hello all :)
I have searched the bug toolkit to no avail, but I see a problem with a pair of 6500s.
Every time a port (any port) enters the STP transistion operation, all my mcast groups get deleted from the switch? I cant see a reason for why this would be normal operation? The port that enters STP state can be any port and does not even run multicast apps on them and is not in the "show multicast group" table.
Can anyone help as this "may" be causing us a GREAT deal of pain for our multicast apps?
Many thx from a troubled engineer :(

Re: ** PLS HELP ** Multicast GDA Deletion after STP change occur
I had this exact problem on our network but with a different series of switches. When a topology change occurs the multicast entries in the CAM table will be purged. Can you enable portfast on these ports to stop them from causing a topology change?
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
