Managing the Ethernet Port on the SRP Module
You can configure the Fast Ethernet management port to access the router from a Telnet session or SNMP.
On ERX-7xx models, ERX-14xx models, and ERX-310 routers, the Fast Ethernet port is located on the SRP I/O module. For more information about configuring the Fast Ethernet port on an SRP I/O module, see ERX Hardware Guide, Chapter 7, Accessing ERX Routers.
Use the Fast Ethernet port on the SRP I/O module only as a router management port. Do not use this port to route traffic for Fast Ethernet or higher-level protocols such as transport or routing protocols, because doing so affects the performance of the router.
On the E120 router and the E320 router, the Fast Ethernet port is located on the SRP IOA. For more information about configuring the Fast Ethernet port on an SRP IOA, see E120 and E320 Hardware Guide, Chapter 7, Accessing E-Series Routers.
interface fastEthernet
- Use to select a Fast Ethernet interface on a line module or an SRP module.
- On ERX-7xx models, ERX-14xx models, and the ERX-310 router, specify the Fast Ethernet interface management port by using the slot/port format.
- On the E120 and E320 routers, you can specify the Fast Ethernet port on the SRP IOA by using the slot/adapter/port format. The port on the SRP IOA is always identified as 0.
- Example 1—Selects a Fast Ethernet management port on ERX-7xx models, ERX-14xx models, or the ERX-310 router
host1(config)#interface fastEthernet 0/0Example 2—Selects a Fast Ethernet management port on the E320 router host1(config)#interface fastEthernet 6/0/0Use the no version to remove IP from an interface or subinterface. Monitoring Statistics
You can set a baseline and view statistics on the Fast Ethernet port of the SRP module in the same way that you would for other Ethernet interfaces. See JUNOSe Physical Layer Configuration Guide, Chapter 5, Configuring Ethernet Interfaces.
Monitoring the Ethernet Configuration for the SRP Module
Slots 0 and 1 are reserved for SRP modules on ERX-7xx models; slots 6 and 7 are reserved for SRP modules on ERX-14xx models, the E120 router, and the E320 router. When you configure the Fast Ethernet interface on an SRP module, the output of the show configuration command always indicates that the interface is configured in the lower of the two slots (slot 0 or slot 6). This indication is true if you configure the interface on a redundant SRP module in the higher slot or even if you have only one SRP module and it is installed in the higher slot, as shown in the following example:
