1-16Configuring Interaction for a ClusterAfter establishing a cluster, you can configure FTP/TFTP server, NM host and log host for the cluster onthe management device.z After you configure an FTP/TFTP server for a cluster, the members in the cluster access theFTP/TFTP server configured through the management device.z After you configure a log host for a cluster, all the log information of the members in the cluster willbe output to the configured log host in the following way: first, the member devices send their loginformation to the management device, which then converts the addresses of log information andsends them to the log host.z After you configure an NM host for a cluster, the member devices in the cluster send their Trapmessages to the shared SNMP NM host through the management device.If the port of an access NM device (including FTP/TFTP server, NM host and log host) does not allowthe packets from the management VLAN to pass, the NM device cannot manage the devices in acluster through the management device. In this case, on the management device, you need toconfigure the VLAN interface of the access NM device (including FTP/TFTP server, NM host and loghost) as the NM interface.Follow these steps to configure the interaction for a cluster:To do… Use the command… RemarksEnter system view system-view —Enter cluster view cluster —Configure the FTP servershared by the clusterftp-server ip-address[ user-name usernamepassword { simple | cipher }password ]RequiredBy default, no FTP server isconfigured for a cluster.Configure the TFTP servershared by the cluster tftp-server ip-addressRequiredBy default, no TFTP server isconfigured for a cluster.Configure the log host sharedby the member devices in theclusterlogging-host ip-addressRequiredBy default, no log host isconfigured for a cluster.Configure the SNMP NM hostshared by the clustersnmp-host ip-address[ community-string readstring1 write string2 ]RequiredBy default, no SNMP host isconfigured.Configure the NM interface ofthe management devicenm-interface vlan-interfaceinterface-name OptionalTo isolate management protocol packets of a cluster from packets outside the cluster, you arerecommended to configure to prohibit packets from the management VLAN from passing the ports thatconnect the management device with the devices outside the cluster and configure the NM interface forthe management device.
