Abstract: A plurality of line cards with each line card having a respective network forwarding engine and a respective outgoing interface (OIF) list and at least one fabric module communicatively coupled with each line card with each fabric module can have a respective network forwarding engine. The local OIF list can be asymmetrically programmed. The network forwarding engine of a line card can be configured to receive a multicast packet, compare a multicast address associate with the received multicast packet with entries in the local OIF list of the line card and forward the received multicast packet to at least one interface associated with the multicast address in response to the comparison resulting in a match.

Abstract: Techniques are provided for mitigating the effects of slow or no drain devices on a fabric. One or more of the described embodiments can be used alone or in combination to address problems associated with inter-switch link blocking and to address the situation where flows which are not associated with slow/no drain devices suffer the negative impacts of slow or no drain devices on a fabric.
