Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

NIC pairing allows you to combine any two physical data ports in order to provide a backup Ethernet 
interface if the data path from the NIC to the upstream Ethernet port should fail. Basically, pairing 
configures the Ethernet interfaces so that there is a primary interface and a backup interface. If the 
primary interface fails (i.e. if the carrier between the NIC and the upstream node is disrupted), the 
backup interface becomes active and an alert is sent. Within Cisco documentation, NIC pairing is 
synonymous with NIC teaming.

NIC pairing is not available on Email Security virtual appliances. 

You can create more than one NIC pair, providing you have enough data ports. When creating pairs, you 
can combine any two data ports. For example:

6. 1000baseTX half-duplex

7. 1000baseTX full-duplex

[1]> 5

Ethernet interfaces:

1. Data 1 (Autoselect: <100baseTX full-duplex>) 00:06:5b:f3:ba:6d

2. Data 2 (100baseTX full-duplex: <100baseTX full-duplex>) 00:06:5b:f3:ba:6e

3. Management (Autoselect: <100baseTX full-duplex>) 00:02:b3:c7:a2:da
