250 BigIron RX Series Configuration Guide53-1001986-01Deploying a LAG8Displaying LAG statisticsYou can display LAG statistics for a BigIron RX switch in either a full or brief mode. Full mode is thedefault and is displayed when the show statistics lag command is executed without the briefoption. The examples below show both options of the show statistics lag command.Syn Indicates the synchronization state of the port. The state can be one ofthe following:• No – The port is out of sync with the remote port. The port does notunderstand the status of the LACPDU process and is not preparedto enter a trunk link.• Syn – The port is in sync with the remote port. The portunderstands the status of the LACPDU message exchange process,and therefore knows the trunk group to which it belongs, the linkaggregation state of the remote port, and so on.Col Indicates the collection state of the port, which determines whether theport is ready to send traffic over the trunk link.• Col – The port is ready to send traffic over the trunk link.• No – The port is not ready to send traffic over the trunk link.Dis Indicates the distribution state of the port, which determines whetherthe port is ready to receive traffic over the trunk link:• Dis – The port is ready to receive traffic over the trunk link.• No – The port is not ready to receive traffic over the trunk link.Def Indicates whether the port is using default link aggregation values. Theport uses default values if it has not received link aggregationinformation through LACP from the port at the remote end of the link.This field can have one of the following values:• Def – The port has not received link aggregation values from theport at the other end of the link and is therefore using its defaultlink aggregation LACP settings.• No – The port has received link aggregation information from theport at the other end of the link and is using the settings negotiatedwith that port.Exp Indicates whether the negotiated link aggregation settings have expired.The settings expire if the port does not receive an LACPDU messagefrom the port at the other end of the link before the message timerexpires. This field can have one of the following values:• Exp – The link aggregation settings this port negotiated with theport at the other end of the link have expired. The port is now usingits default link aggregation settings.• No – The link aggregation values that this port negotiated with theport at the other end of the link have not expired, so the port is stillusing the negotiated settings.Ope • Ope (operational) - The port is operating normally.• Blo (blocked) - The port is blocked because the adjacent port is notconfigured with link aggregation or because it is not able to join atrunk group. An LACP port is blocked until it becomes part of atrunk. Also, an LACP is blocked if its state becomes “default”. Tounblock the port and bring it to an operational state, enable linkaggregation on the adjacent port and ensure that the ports havethe same key.TABLE 58 Show LAG information (Continued)This field...
