To convert the above system into a dual homing setup, perform the following:
1 Repeat the steps 2 to 7 from Systems with Port Extender.
2 Change the uplink port connections of the PE, so that the uplink ports are connected to each of the VLT peers. In the above example,
the link connected to Te 0/1 in System A is disconnected and connected to Te 1/4 in System B.
3 Remove the disconnected interface (Te 0/1) from the configuration mode of PE 1 in System A. The configuration would be already
available in System A and needs to be removed.
PE CONFIGURATION (BATCH mode)
no cascade interface interface slot/port
Dell(conf-b-pe-1)# no cascade interface TenGigabitEthernet 0/1
4 Configure the cascade interface of the System B through the batch mode of System A and commit the configuration.
PE CONFIGURATION (BATCH mode)
cascade interface interface slot/port peer
Dell(conf-b-pe-1)# cascade interface TenGigabitEthernet 1/4 peer
Once the cascade interfaces are configured, the PE starts functioning in a dual homing setup as shown in the following diagram:

You can configure PE 1 from both System A and System B.
