Operation Manual – Stack-Cluster
H3C S3100-52P Ethernet Switch
Cluster management requires the packets of the management VLAN be permitted on
ports connecting the management device and the member/candidate devices.
Therefore:
If the packets of management VLAN are not permitted on a candidate device port
connecting to the management device, the candidate device cannot be added to
the cluster. In this case, you can enable the packets of the management VLAN to
be permitted on the port through the management VLAN auto-negotiation
function.
Packets of the management VLAN can be exchanged between the management
device and a member device/candidate device without carrying VLAN tags only
when the default VLAN ID of both the two ports connecting the management
device and the member/candidate device is the management VLAN. If the VLAN
IDs of the both sides are not that of the management VLAN, packets of the
management VLAN need to be tagged.
Note:
The management VLAN interface is used as the network management interface.
There is only one network management interface on a management device; any
newly configured network management interface will overwrite the old one.
VI. Tracing a device in a cluster through destination address
In practice, you may need to do the following:
Check whether there is a loop in a cluster.
Locate which port on which device in a cluster generates the network attacks.
Determine the device and the port to which a MAC address corresponds.
Locate the fault device in a cluster.
Check whether a link in a cluster and the devices on the link are consistent with the
original design.
To do the above things, you can use the tracemac command to trace a device in a
cluster by specifying the destination MAC address or IP address.
The following describes the process:
1) Choose to use the destination MAC address or the destination IP address to trace
a device in a cluster:
If you specify a destination MAC address in the tracemac command, the switch
will query its local MAC address table according to the MAC address and VLAN ID
specified in the command parameters to find out the port connected with a
downlink switch.
