System A is the primary controlling bridge and System B is the secondary. When the primary system goes down, the secondary
system acts as primary and controls the PEs. The common PE configurations are synchronized between the systems when
configured using the Configuration Terminal Batch mode.
NOTE: When multiple PEs are connected in a dual homing setup, ensure that each PE has an unique ID so that the IDs do
not overlap during the configuration.
Configuration Terminal Batch Mode
The C9010 platform with Dell Networking OS 9.10(0.0) supports the Configuration Terminal Batch mode. You should perform
the common PE configurations using this mode.
To enter Configuration Terminal Batch mode:
1. Verify that you are logged in to EXEC Privilege mode.
2. Enter the configure terminal batch command. The prompt changes to include (conf-b).
You can return to EXEC mode by using the exit command.
Setting up Dual Homing
You can setup dual homing when:
1. There are two systems (CBs) and both have PEs connected to them. You can physically connect the CBs and then configure
them as VLT peers to convert the system into dual homing setup. Refer to Systems with Port Extender.
2. There is a CB connected to PE and a standalone CB. You can physically connect the CBs and then configure them as VLT
peers. Then physically connect the uplink ports of the PE to each of the VLT peers. The system starts functioning as a dual
homing setup. Refer to Standalone System.
3. There are two standalone CBs not connected to PEs. You can physically connect the CBs and then configure them as VLT
peers. Then physically connect the uplink ports of the PE to the VLT peers. The system starts functioning as a dual homing
setup. Refer to Systems without Port Extender on page 720.
NOTE:
PE up-time reflects the duration of time for which the PE is up. However, during an ICL flap or reload scenario, PE
up-time is not synced between the VLT peers. As a result, both the VLT nodes run their own timers after an ICL flap or
reload occurs.
