Table 53   Clustering Management Configuration 

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 20 

printable characters (no 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 these changes to the switch.

Cancel

Click Cancel to begin configuring this part of the 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.
