NETGEAR 8800 User Manual configure sharing health-check member-port add tcp-tracking {tcp-port frequency misses } If the TCP-port, frequency, or misses are not specified, the defaults described in the NETGEAR 8800 Chassis Switch CLI Manual are used. 3. Add the LAG to a VLAN whose subnet is the same as the configured tracking IP addresses. configure vlan add port [tagged | untagged] All of the tracking IP addresses must be in the same subnet in which the LAG belongs. Note: VLANs to which Health Check LAG ports are to be added must be configured in loopback mode. This is to prevent the VLAN interface from going down if all ports are removed from the Health Check LAG. In a normal LAG when all ports are removed from the aggregator, the trunk is considered DOWN. As a consequence, if this were the only port in the VLAN, the VLAN interface would be brought DOWN as well. In the Health Check LAG situation, this would cause the TCP monitoring to fail because the L3 vlan interface used by TCP monitoring would no longer send or receive TCP data. The following commands are used to modify the configured Health Check LAG. 1. Delete the monitoring configuration for a member port using the following command: configure sharing health-check member-port delete tcp-tracking {tcp-port } 2. Enable or disable monitoring for a member port in the Health Check LAG using the following command: configure sharing health-check member-port [disable | enable] tcp-tracking Load-Sharing Examples This section provides examples of how to define load sharing, or link aggregation, on stand-alone and modular switches, as well has defining dynamic link aggregation. Load Sharing on a Stand-alone Switch The following example defines a static load-sharing group that contains ports 9 through 12, and uses the first port in the group as the master logical port 9: enable sharing 9 grouping 9-12 In this example, logical port 9 represents physical ports 9 through 12. When using load sharing, you should always reference the master logical port of the load-sharing group (port 9 in the previous example) when configuring or viewing VLANs; the Chapter 5.
