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:
Figure 112. Standalone System and System with PE — After setting up Dual Homing
You can configure PE 1 from both System A and System B.
Systems without Port Extender
You can connect two standalone systems in a VLT domain and then connect a PE to the systems to setup a dual homed environment. In
the following illustration, System A and System B are standalone systems.
Figure 113. Systems without Port Extender— Before setting up Dual Homing
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. Physically connect a PE to System A. Connect the uplink port connections of the PE, to the VLT peers. For example, connect the
uplink ports to Te 0/0 to System A and Te 1/4 in System B.
