Enabling/Disabling Smart Autosensing
Smart autosensing allows autonegotiating multi-speed ports, such as 10/100 Mbps or
100/1000 Mbps, to monitor and detect errors in the “physical” interconnection to another
port and react accordingly. For example, smart autosensing can detect network
problems, such as an unacceptably high error rate (set in a pre-defined threshold), or a
1000 Mbps link that fails to establish, or a poor quality cable. If both ends of the link
support 100/1000 Mbps autonegotiation, where one end is connected to a 100 Mbps port
and the other is connected to a 1000 Mbps port, then autosensing tunes the link to 100
Mbps to provide you with an error-free 100 Mbps connection to the network.
An SNMP Trap can be sent every time a port is down-rated to a lower speed.
Smart Autosense will not operate on links that do not support auto-negotiation, or
on links where one end is at a fixed speed.
You can enable or disable smart autosense on the Switch using the smartAutosense
command on the Ethernet menu.
To enable or disable the smart autosensing:
1. At the Top-level menu, enter:
physicalInterface ethernet smartAutosense
The following prompt is displayed:
Enter new value (enable,disable) [enable]:
2. Enter enable or disable.
