VLAN Synchronization
VLAN Synchronization
VLAN synchronization is provided to synchronize the EM with the VLAN information present in the
network. The synchronization process gets the VLAN information from the devices in the network and
all the previous VLAN information is lost. Once the VLAN synchronization is completed, all the VLAN
objects and the sub-interfaces are deployed under a DefaultDomain. See “VLAN View” section on
page 2-12 for more details on domains.
Note It is recommended that synchronization should not to be performed at a time when there is heavy load
on the system i.e., when all the chassis are in the performance logging state.
The first time sync is a clean sync which means that the VLAN information from the entire network is
cleaned up and then retrieved.
VLAN synchronization happens only on the chassis which are in the managed state i.e., normal or
performance logging state.
To synchronize the VLAN objects, proceed as follows:
Step 1 Right click on a domain in the VLAN view and choose Cisco 12000/10720 Manager>
Configuration>VLAN Management>Synchronize. The VLAN synchronization dialog can be
launched from the VLAN view or see Table 13-1 on page 13-2 for information on which objects allow
you to launch the VLAN Synchronize window.
