{ Member switches send their log information to the management switch
{ The management switch converts the addresses of log information and sends them to the log
host.
• After you configure an NM host for a cluster, the member switches in the cluster send their Trap
messages to the shared SNMP NM host through the management switch.
If the port of an access NM switch (including FTP/TFTP server, NM host and log host) does not allow the
packets from the management VLAN to pass, the NM switch cannot manage the switches in a cluster
through the management switch. In this case, on the management switch, you need to configure the
VLAN interface of the access NM switch (including FTP/TFTP server, NM host and log host) as the NM
interface.
Follow these steps to configure the interaction for a cluster:

Configure the FTP server shared by
the cluster
ftp-server ip-address [ user-name
username password { simple |
cipher } password ]
Required
By default, no FTP server is
configured for a cluster.
Configure the TFTP server shared
by the cluster
tftp-server ip-address
Required
By default, no TFTP server is
configured for a cluster.
Configure the log host shared by
the member switches in the cluster
logging-host ip-address
Required
By default, no log host is
configured for a cluster.
Configure the SNMP NM host
shared by the cluster
snmp-host ip-address
[ community-string read string1
write string2 ]
Required
By default, no SNMP host is
configured.
Configure the NM interface of the
management switch
nm-interface vlan-interface
interface-name
Optional
CAUTION:
To isolate management protocol packets of a cluster from packets outside the cluster, you are
recommended to configure to prohibit packets from the management VLAN from passing the ports that
connect the management switch with the switches outside the cluster and configure the NM interface for
the management switch.
SNMP configuration synchronization function
Using the SNMP configuration synchronization function facilitates management of a cluster, with which
you can perform SNMP-related configurations on the management switch and synchronize them to the
member switches on the whitelist. This operation is equal to configuring multiple member switches at one
time. It simplifies the configuration process.
Follow these steps to configure the SNMP configuration synchronization function:
