Network Considerations for a Multiviewer Cluster
• If you change the system name or IP address of a cluster member while another cluster
member is offline or otherwise unavailable, the cluster’s integrity will be broken. If you
attempt to make such a change, XEdit will alert you of the situation, prompting you to
cancel the operation and try again later, when all cluster members are available.
However, in the advent that such a change was made by mistake, or that it as been
forced for some reason, you will have to repair the broken cluster (see “Repairing a
Cluster System” in the Kaleido Software User’s Manual
; see Related Documentation
, on
page 15).
• To maintain the integrity of a cluster configuration, such changes must be made by
using the system configuration features available in XAdmin.
Port Used for Transport Notes
161 SNMP UDP Used for SNMP (Simple Network Management Protocol)
communications between external SNMP managers and a
multiviewer (e.g., sending get, get-next, and set messages
to a multiviewer’s SNMP agent, and receiving the response).
Port Used for Transport Notes
123 NTP TCP Used for Network Time Protocol synchronization. Port
needs to be open in both directions.
IMPORTANT
Before changing the system name or IP address of a multiviewer
associated with a cluster, review the following.
