Using E-Trunk Between Multiple PEs Connected to a CE

Using E-Trunk Between Multiple PEs Connected to a CE


E-Trunk is supported by only the following models: S1720X, S1720X-E, S5720EI, S5720HI, S5720I-SI, S5720S-SI, S5720SI, S5730HI, S5730S-EI, S5730SI, S6720EI, S6720HI, S6720LI, S6720S-EI, S6720S-LI, S6720S-SI, and S6720SI.

As shown in Figure 3-18, the Enhanced Trunk (E-Trunk) protects the links between CE1 and two PEs (PE1 and PE2) on the network. CE1 is connected to PE1 and PE2 using two Eth-Trunks in LACP mode. The two Eth-Trunks form an E-Trunk to implement backup and enhance the network reliability.
