Table 179 Management > Cluster Management > Configuration
LABEL DESCRIPTION
Clustering Manager
Active Select Active to have this Switch become the cluster manager switch. A cluster can
only have one manager. Other (directly connected) switches that are set to be cluster
managers will not be visible in the Clustering Candidates list. If a switch that was
previously a cluster member is later set to become a cluster manager, then its Status is
displayed as Error in the Cluster Management Status screen and a warning icon
( ) appears in the member summary list below.
Name Type a name to identify the Clustering Manager. You may use up to 32 printable
characters (spaces are allowed).
VID This is the VLAN ID and is only applicable if the Switch is set to 802.1Q VLAN. All
switches must be directly connected and in the same VLAN group to belong to the same
cluster. Switches that are not in the same VLAN group are not visible in the Clustering
Candidates list. This field is ignored if the Clustering Manager is using Port-based
VLAN.
Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch loses
these changes if it is turned off or loses power, so use the Save link on the top
navigation panel to save your changes to the non-volatile memory when you are done
configuring.
Cancel Click Cancel to begin configuring this screen afresh.
Clustering
Candidate
The following fields relate to the switches that are potential cluster members.
List A list of suitable candidates found by auto-discovery is shown here. The switches must
be directly connected. Directly connected switches that are set to be cluster managers
will not be visible in the Clustering Candidate list. Switches that are not in the same
management VLAN group will not be visible in the Clustering Candidate list.
Password Each cluster member’s password is its web configurator password. Select a member in
the Clustering Candidate list and then enter its web configurator password. If that
switch administrator changes the web configurator password afterwards, then it cannot
be managed from the Cluster Manager. Its Status is displayed as Error in the
Cluster Management Status screen.
If multiple devices have the same password then hold [SHIFT] and click those switches
to select them. Then enter their common web configurator password.
Add Click Add to save your changes to the Switch’s run-time memory. The Switch loses
these changes if it is turned off or loses power, so use the Save link on the top
navigation panel to save your changes to the non-volatile memory when you are done
configuring.
Cancel Click Cancel to begin configuring this screen afresh.
Refresh Click Refresh to perform auto-discovery again to list potential cluster members.
The next summary table shows the information for the clustering members configured.
Index This is the index number of a cluster member switch.
MacAddr This is the cluster member switch’s hardware MAC address.
Name This is the cluster member switch’s System Name.
Model This is the cluster member switch’s model name.
Select an entry’s check box to select a specific entry. Otherwise, select the check box in
the table heading row to select all entries.
Remove Click the Remove button to remove the selected cluster member switch(es) from the
cluster.
Cancel Click Cancel to begin configuring this screen afresh.
