Hi ,

This is regarding IPTV channel freezing issue which I am facing these days,

We have some 100 no's of vlan in one of our PE for IPTV, out of that from one of the VLAN which is conencting to one access switch, users are facing issue with channel freezing..I had extended another vlan and its work fine..

When  this issue happend the resident normally needs to channel up and channel down to unfreeze a certain channel.
