NOTE: If you do not enable LiveLink™ when configuring teams, disabling Spanning Tree Protocol (STP) at the switch is recommended. This minimizes the downtime due to the spanning tree loop determination when failing over. LiveLink mitigates such issues. LiveLink™ Functionality LiveLink™ functionality is a feature of BASP that is available only for the Smart Load Balancing™ and Failover type of teaming. The purpose of LiveLink is to detect network connectivity beyond the switch and to route traffic only through team members that have a live link. This function is accomplished though the teaming software (see Configuring LiveLink for a Smart Load Balancing and Failover and SLB (Auto-Fallback Disable) Team). The teaming software periodically probes (issues a link packet from each team member) one or more specified target network adapter(s). The probe target(s) responds when it receives the link packet. If a team member does not detect a response within a specified amount of time after a specified number of retries, the teaming software discontinues passing traffic through that team member. Later, if that team member begins to detect a response from a probe target, this indicates that the link has been restored, and the teaming software automatically resumes passing traffic through that team member. LiveLink works only with TCP/IP. LiveLink™ functionality is supported in both 32-bit and 64-bit Windows operating systems, but is not supported in NetWare systems. For similar functionality in Linux operating systems, refer to Channel Bonding in your Red Hat documentation. Teaming and Large Send Offload/Checksum Offload Support Large Send Offload (LSO) and Checksum Offload are enabled for a team only when all of the members support and are configured for the feature.

LiveLink™ Functionality
LiveLink™ functionality is a feature of BASP that is available only for the Smart Load Balancing™ and Failover type of
teaming. The purpose of LiveLink is to detect network connectivity beyond the switch and to route traffic only through team
members that have a live link. This function is accomplished though the teaming software (see
Configuring LiveLink for a
Smart Load Balancing and Failover and SLB (Auto-Fallback Disable) Team
). The teaming software periodically probes (issues
a link packet from each team member) one or more specified target network adapter(s). The probe target(s) responds when
it receives the link packet. If a team member does not detect a response within a specified amount of time after a specified
number of retries, the teaming software discontinues passing traffic through that team member. Later, if that team member
begins to detect a response from a probe target, this indicates that the link has been restored, and the teaming software
automatically resumes passing traffic through that team member. LiveLink works only with TCP/IP.
LiveLink™ functionality is supported in both 32-bit and 64-bit Windows operating systems, but is not supported in NetWare
systems. For similar functionality in Linux operating systems, refer to Channel Bonding in your Red Hat documentation.
Teaming and Large Send Offload/Checksum Offload Support
Large Send Offload (LSO) and Checksum Offload are enabled for a team only when all of the members support and are
configured for the feature.
