Patent ID: 8850062

Claim:
A method, comprising: configuring a connectivity verification protocol (CVP) session for a particular virtual interface (VI) on a particular group of two or more line cards (LCs) on a network device; transmitting CVP session packets from the group of LCs onto the particular VI through ingress path processing on the network device, wherein the network device egresses the transmitted CVP session packets onto an LC of the network device currently responsible for the VI egress, each of the two or more LCs of the particular group transmitting the CVP session packets at a reduced rate, a combination of CVP session packets at the reduced rate from the two or more LCs of the particular group being sufficient to maintain the CVP session based on a negotiated CVP full rate; in response to receiving CVP session packets for the VI on an LC of the network device currently responsible for the VI ingress, forwarding the received CVP session packets to the particular group of two or more LCs; and processing the received CVP session packets by at least one of the two or more LCs within the particular group.
