SmartRedundancy 3-17
SmartRedundancy SmartRedundancy for the Switch 3800 refers to fail-over behavior of
the main and standby Gigabit Ethernet ports. SmartRedundancy allows
the Switch to always use the main link if it is available. For example, if
only the standby link is available it will be used, but if the main link
becomes available again the link will switch back to the main from the
standby. With SmartRedundancy disabled, the first link available will be
used; only if that link becomes unavailable will the Switch attempt to
use the other link. By default, SmartRedundancy is enabled.
Port Commands Table 3-8 describes port commands.
Table 3-8 Port Commands
Command Description
config port auto on Allows you to enable autonegotiation on a 10/100
Mbps or Gigabit port.
config port auto off {speed
[10 | 100]} duplex [half | full] Allows you to change the configuration of a group of
10/100 Mbps ports. Specify the following:
■
auto off — The port will not autonegotiate the
settings.
■
speed — The speed of the port (for 10/100 Mbps
ports only).
■
duplex — The duplex setting (half- or full-duplex).
config port auto off duplex
full Allows you to disable autonegotiation on a Gigabit
port.
enable port Allows you to enable one or more ports.
enable sharing grouping
Allows you to define a load-sharing group of ports.
The ports specified in are grouped to the
master port.
enable smartredundancy Allows you to enable the SmartRedundancy feature on
the redundant Gigabit Ethernet port. When the
SmartRedundancy feature is enabled, the Switch
always uses the primary link when the primary link is
available. The default setting is enabled.
disable port Allows you to disable one or more ports. Even when
disabled, the link is available for diagnostic purposes.
disable sharing Allows you to disable a load-sharing group of ports.
