Ethernet Ports Switching Overview
You can deploy supported devices in branch offices as an access or desktop switch with integrated routing capability, thus eliminating intermediate access switch devices from your network topology. The Ethernet ports provide switching while the Routing Engine provides routing functionality, enabling you to use a single device to provide routing, access switching, and WAN interfaces.
Supported Devices and Ports
Juniper Networks supports switching features on the following Ethernet ports and devices:
- Multiport Gigabit Ethernet uPIMs on the J Series device
- Onboard Ethernet ports (Gigabit and Fast Ethernet built-in ports) on the SRX100, SRX210, and SRX240 devices
- Multiport Gigabit Ethernet XPIM on the SRX650 device
Table 3: Supported Devices and Ports for Switching Features
Device | Ports |
|---|---|
J Series devices | Multiport Gigabit Ethernet uPIMs |
SRX240 devices | Onboard Gigabit Ethernet ports (ge-0/0/0 through ge-0/0/15) |
SRX210 devices | Onboard Gigabit Ethernet ports (ge-0/0/0 and ge-0/0/1) Onboard Fast Ethernet ports (fe-0/0/2 and fe-0/0/7) |
SRX100 devices | Onboard Fast Ethernet ports (fe-0/0/0 and fe-0/0/7) |
SRX650 devices | Multiport Gigabit Ethernet XPIM modules |
On J Series and SRX650 devices, you can set multiport switch modules (uPIMs and XPIMs, respectively) to three modes of operation: routing (the default), switching, or enhanced switching. Routed traffic is forwarded from any port of the Gigabit Ethernet uPIM to the WAN interface. Switched traffic is forwarded from one port of the Gigabit Ethernet uPIM to another port on the same Gigabit Ethernet uPIM. Switched traffic is not forwarded from a port on one uPIM to a port on a different uPIM.
On the SRX100, SRX220, and SRX240 devices, you can set the onboard Gigabit Ethernet ports to operate as either switched ports or routed ports.
