Configuring Loopback Testing On An Ethernet Interface - HP A3100-8 v2 SI Configuration Manual

Configuring link-down event suppression
Follow these steps to enable an Ethernet interface to suppress link-down events:
To do...
Enter system view
Enter Ethernet interface view
Set a link-down event suppression
interval
Configuring link-up event suppression
Follow these steps to configure link-up event suppression on an Ethernet interface:
To do...
Enter system view
Enter Ethernet interface view
Set a link-up event suppression
interval
NOTE:
The link-delay mode up command and the link-delay command supersedes each other, and whichever is
configured last takes effect.

Configuring loopback testing on an Ethernet interface

You can perform loopback testing on an Ethernet interface to determine whether the interface functions
properly. The Ethernet interface cannot forward data packets during the testing. Loopback testing falls
into the following categories:
Internal loopback testing, which tests all on-chip functions related to Ethernet interfaces. As shown
•
in Figure
interface sends a certain number of test packets, which are looped back to the interface over the
self-loop created on the switching chip.

External loopback testing, which tests the hardware of Ethernet interfaces. As shown in

external loopback testing is performed on Port 1. To perform external loopback testing on an
