246 BigIron RX Series Configuration Guide53-1002253-01Deploying a LAG8Monitoring an individual LAG portBy default, when you monitor the primary port in a LAG group, aggregated traffic for all the ports inthe LAG is copied to the mirror port. You can configure the device to monitor individual ports in aLAG including Ethernet, or Named ports. You can monitor the primary port or a secondary portindividually.NOTEYou can use only one mirror port for each monitored trunk port. To monitor traffic on an individualport in a trunk group, enter commands such as the following:This command enables monitoring of an individual port within a LAG.BigIron RX(config)# lag blue staticBigIron RX(config-lag-blue)# deployBigIron RX(config-lag-blue)# monitor ethe-port-monitored 3/1 ethernet 10/3 bothSyntax: [no] monitor ethe-port-monitored [slot/port] | named-port-monitored [name] ethernet[slot/port] [ input | output | both ]Use the ethe-port-monitored option with the appropriate [slot/port] variable to specify a Ethernetport within the LAG that you want to monitor.Use the named-port-monitored option with the appropriate [slot/port] variable to specify a namedport within the LAG that you want monitor.The ethernet parameter specifies the port to which the traffic analyzer is attached.The input | output | both parameters specify the traffic direction to be monitored.NOTEMirror (analyzer) ports cannot be assigned to the 16x10G card. You can monitor traffic on 16x10ports.Assigning a name to a port within a LAGYou can assign a name to an individual port within a LAG using the port-name command within theLAG configuration as shown in the following.BigIron RX(config)# lag blue staticBigIron RX(config-lag-blue)# deployBigIron RX(config-lag-blue)# port-name orange ethernet 3/1Syntax: [no] port-name ethernet [slot/port]The variable specifies the port name. The name can be up to 50 characters long.Use the ethernet option with the appropriate [slot/port] variable to apply the specified name to anEthernet port within the LAG.Refer to “Allowable characters for LAG names” on page 13 for guidelines on LAG namingconventions.Enabling sFlow forwarding on a port within a LAGYou can enable sFlow forwarding on an individual port within a LAG using the sflow-forwardingcommand within the LAG configuration as shown in the following.
