Cluster Configuration Task List - H3C S3100-52P Operation Manual

Operation Manual – Stack-Cluster
H3C S3100-52P Ethernet Switch
If you specify a destination IP address in the tracemac command, the switch will
query its local ARP address table according to the IP address to find out the
corresponding MAC address and VLAN ID. In this way, the switch can find out the
port connected with a downlink switch.
2) After the switch finds out the port connected with a downlink switch, it sends a
multicast packet carrying the VLAN ID and hop limit to the port. After the downlink
switch receives the packet, it compares its MAC address with the specified
destination MAC address:
If the same, the downlink switch will send a response to the switch sending the
multicast packet, indicating that the tracemac command is executed successfully.
If different, the downlink switch will find the port connected with a downlink switch
according to the destination MAC address and VLAN ID, and forwards the
multicast packet to its downlink switch through the port. If a switch matching the
destination MAC address is found within the specified hops, the switch will send a
response to the switch sending the multicast packet, indicating that the tracemac
command is executed successfully. If no switch matches the destination MAC
address (or IP address) within the specified hops, the multicast packet will not be
forwarded to a downlink switch anymore.
Note:
If the queried IP address has a corresponding ARP entry, but the MAC address
entry corresponding to the IP address does not exist, the trace of the device fails.
To trace a specific device using the tracemac command, make sure that all the
devices passed support the tracemac function.
To trace a specific device in a management VLAN using the tracemac command,
make sure that all the devices passed are within the same management VLAN as
the device to be traced.

2.2 Cluster Configuration Task List

Before configuring a cluster, you need to determine the roles and functions the
switches play. You also need to configure the related functions, preparing for the
communication between devices within the cluster.
Complete the following tasks to configure cluster:
Configuring the Management Device
Configuring Member Devices
Managing a Cluster through the Management Device
