The following table describes the labels in this screen.

Table 76 Configuring Cluster Management

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 Management VLAN ID and is only applicable if the switch is set to 802.1Q

 

VLAN. All switches must be in the same management VLAN group to belong to the

 

same cluster. Switches that are not in the same management VLAN group are not visible

 

in the Clustering Candidates list. This field is ignored if the Clustering Manager is

 

using Port-basedVLAN.

 

 

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 part of the screen afresh.

 

 

Clustering

The following fields relate to the switches that are potential cluster members.

Candidate

 

 

 

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 and a warning icon ( ) appears in the member summary

 

list below.

 

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 part of the screen afresh.

 

 

Refresh

Click Refresh to perform auto-discovery again to list potential cluster members.

 

 

The next summary table shows the devices selected for clustering.

Index

This is the index number of a cluster member switch.

 

 

MAC

This is the cluster member switch’s hardware MAC address.

Address

 

 

 

Name

This is the cluster member switch’s System Name.

 

 

Model

This is the cluster member switch’s model name.

 

 

Remove

Select this checkbox and then click the Remove button to remove a cluster member

 

switch from the cluster.
