Managing the Ethernet Port on the SRP Module

For information about configuring the Fast Ethernet port on the SRP I/O module, see ERX Installation and User Guide, Chapter 5, .

Use the Fast Ethernet port on the SRP I/O module only as a system management port. Do not use this port to route Fast Ethernet traffic, because doing so affects the performance of the system.

Use an FE-2 line module and an FE-2 I/O module or a GE/FE line module and an FE-8 I/O module to route 10/100BaseT traffic. For information about configuring Ethernet interfaces, see Chapter 6, Configuring Ethernet Interfaces.

    interface fastEthernet

• Use to select an FE interface on a line module or SRP module.
• Example

host1-0-1-90(config)#interface fastEthernet 1/0

• Use 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 I/O module in the same way that you would for other Ethernet interfaces. See Chapter 6, Configuring Ethernet Interfaces.

Monitoring the Ethernet Configuration for the SRP Module

Slots 0 and 1 are reserved for SRP modules on the ERX-700 series; slots 6 and 7 are reserved for SRP modules on the ERX-1400 series. When you configure the Fast Ethernet interface on an SRP module, the output of the show config command always indicates that the interface is configured in the lower of the two slots (slot 0 or slot 6). This 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:
