Juniper Networks/Cisco Systems Switch Interoperability Cookbook

! ! !

Juniper switches can carry Cisco and other vendors’ Wi-Fi traffic transparently, with no

special configuration required.

Topology!

As shown in Figure 18, a centrally located Cisco 5508 Wi-Fi controller in a data center

must communicate with Cisco 3602 and Cisco 3702 APs in a campus network. The Cisco

controller connects with a Juniper EX9208 core switch. The Cisco APs connect with a

Juniper EX4300 access switch using the Power Over Ethernet Plus (PoE+) specification.

The Cisco controller and APs both use the default VLAN, which here uses a VLAN

ID of 1. Trunk ports between the Juniper switches allow traffic from all VLANs.

No special configuration is needed on the Juniper switches. In this example, both access

and trunk ports are members of the default VLAN, and the trunk port between switches

allows traffic from all VLANs.

On the Juniper EX9208 switch:

1. Create a VLAN called default and assign a VLAN ID of 1:

admin@ex9208> configure

admin@ex9208# set vlans default vlan-id 1
