A10E/A28E/A28F Configuration Guide
Alpha-A28E(config)#switchport
backup restore-mode { disable |
neighbor-discover | port-up }
(Optional) configure restoration
mode.
In an interface backup group, an interface is either a primary interface or a backup
interface.
In a VLAN, an interface or a link aggregation group cannot be a member of two
interface backup groups simultaneously.
If you set a link aggregation group as a member of interface backup group, you
need to set the member with the minimum interface ID in the link aggregation group
as the member. When the member is in Up status, this indicates that the link
aggregation group has a Up interface. When the member is in Down status, this
indicates that all interfaces in the link aggregation group are Down.
7.2.5 (Optional) configuring force switching on interfaces
After force switching is successfully configured, the primary/backup link will be
switched; namely, the current link is switched to the backup link (without considering
Up/Down status of the primary/backup interface). For example, when both the
primary interface and backup interface are in Up status, the primary link transmits
data. In this situation, if you perform forcible switchover, the working link changes
from the primary link to the backup link.
In the force switching command, the backup interface number is optional. If the
primary interface is configured with multiple interface backup groups, you should
input the backup interface ID.
Configure force switching on interfaces for the A10E/A28E as below.
Enter global configuration mode.
Alpha-A28E(config)#interface
port
port-id
Enter physical layer interface
configuration mode.
Alpha-A28E(config-
port)#switchport backup
[ port
port-id
] force-switch
Configure force switching on the
interface.
