Configuring the temperature thresholds for a card
The switch sends traps when the temperature of a card crosses the lower or upper temperature threshold.
You can change the temperature threshold settings for a card as needed so you can remove the alarm
condition in time.
Follow these steps to configure and display the temperature thresholds for a card:

• The alarming threshold:97
The warning and alarming

Port configuration and management
Configuring a combo interface
What is a combo interface
On an S7500E switch, a combo interface is a logical interface that comprises one SFP fiber port and one
RJ-45 copper Ethernet port, which are called combo ports. The two ports share one forwarding interface
and cannot work simultaneously. When you enable the RJ-45 port, the SFP port is automatically disabled
and placed in the inactive state, and vice versa. By default, the port with a smaller number is active.
Configuration prerequisites
1. Use the display port combo command to identify the combo interfaces on the switch and the active
status of their member ports.

2. Use the display interface interface-type interface-number command to identify the medium type of
a combo port:
