Cisco Cisco Email Security Appliance C170 Guia Do Utilizador

When creating NIC pairs, you must specify a name to use to refer to the pair. NIC 
pairs created in versions of AsyncOS prior to version 4.5 will automatically 
receive the default name of ‘Pair 1’ following an upgrade.

Any alerts generated regarding NIC pairing will reference the specific NIC pair 
by name.

Once you have verified your ethernet media setting, use the 

etherconfig

 

command to configure NIC pairing. You will be prompted for a name to use to 
refer to the pair. 

The 

failover

 sub-command switches the active interface. The system will not 

automatically switch back to the primary NIC when it comes back on line and the 
backup interface will remain active in that case until you explicitly switch the 
system back over to the primary NIC (by using the 

failover

 command) or unless 

the backup NIC has a failure. See 

Use the 

delete

 subcommand to remove NIC pairs.

When configuring NIC pairing, keep in mind that all configuration changes 
require a commit, except for 

failover

. The 

failover

 command force a failover 

during the next polling interval which is every 15 seconds once NIC pairing 
configuration has been committed.

If you enable NIC pairing on an interface that has listeners assigned to it, you are 
prompted to either delete, reassign, or disable all listeners assigned to the backup 
interface.
