Ethernet Interface Configuration Window—Detailed Description

The Ethernet Interface Configuration window displays two tabs: Configuration and HSRP Parameters.

Configuration Tab

The Configuration tab (see Figure 8-3 on page 8-10) contains a single General area.

General

The General area displays the following fields:

Loopback—The following options are available:

Internal—No cable is needed to connect the input and output ports. The data is looped back within the device itself. Applicable only for Gigabit and Fast Ethernet interfaces.

External—Input and output ports are physically connected by a cable to simulate a loopback. When data is transmitted, it travels through the output port and enters the device through the input port. Applicable only for Gigabit and Fast Ethernet interfaces.

Enabled—Packets are transmitted back to the source to test the interface functionality and ensure that packets transmitted through the interface reach the destination. Applicable only for GRP Ethernet interfaces.

Caution When the loopback for the Ethernet interface in the GRP is enabled, the Ethernet communication link to the Cisco 12000 Series Router will be lost.

Note If the communication link to the Cisco 12000 Series Router is lost it cannot be switched on again from Cisco EMF, and access to the Cisco 12000 Series Router is required before the link can be re-enabled.

Disabled—Disables switches loopback off for GRP, Fast and Gigabit Ethernet interfaces.

Keepalive Period—Displays set the keepalive period. The system sends packets after this interval to know if the interface or the network is up for routing packets. By default this interval is 10 seconds.

HSRP Parameters Tab

The HSRP Parameters tab (see Figure 8-4 on page 8-11) displays a Configured Group Numbers field and an HSRP Parameters area.

Configured Group Numbers—List of configured HSRP group numbers.
