Configuring Interaction for a Cluster 
After establishing a cluster, you can configure FTP/TFTP server, NM host and log host for the cluster on 
the management device. 
z  After you configure an FTP/TFTP server for a cluster, the members in the cluster access the 
FTP/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 will 
be output to the configured log host in the following way: first, the member devices send their log 
information to the management device, which then converts the addresses of log information and 
sends them to the log host. 
z  After you configure an NM host for a cluster, the member devices in the cluster send their Trap 
messages 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 allow 
the packets from the management VLAN to pass, the NM device cannot manage the devices in a 
cluster through the management device. In this case, on the management device, you need to 
configure the VLAN interface of the access NM device (including FTP/TFTP server, NM host and log 
host) as the NM interface. 
Follow these steps to configure the interaction for a cluster:
