40 Ethernet module configuration using the CLIVariable definitionsUse the following table to help you configure 1 Gigabit Ethernet portoperational parameters using the config ethernet command.Configuring 10 Gigabit Ethernet portsConfigure Ethernet parameters for 10 Gbit/s (XFP) ports so that theyoperate optimally for your network conditions.ATTENTIONEnsure that all ports that belong to the same MLT/LACP group use the sameport speed.Procedure stepsStep Action1 If required, enable the port by using the following command:config ethernet state 2 Configure the clock source:config ethernet clock-source ne>3 Configure tx-flow-control:config ethernet tx-flow-control4 Enable PAUSE frames:config ethernet fc-pause0 5 Configure the flow-control-pause timer:config ethernet fc-pause-time <1...65535>6 For LAN/WAN modules, configure the mode:config ethernet wan-mode When you configure multiple ports of the 8683XZR module toWAN mode, the framing type and clock mode must be the samefor all the WAN mode ports. Mixed configurations for multipleWAN mode enabled ports is not supported.7 If the mode is WAN, configure the framing type:config ethernet framing 8 Use the following variable definitions table to configure otherparameters as required.9 Ensure that your configuration is correct by using one of thefollowing commands:Nortel Ethernet Routing Switch 8600Configuration — Ethernet ModulesNN46205-503 04.01 21 December 2009Copyright © 2008-2009 Nortel Networks.
