Configure Ports Redundant - Extreme Networks ExtremeWare XOS Command Reference Manual

ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.

configure ports redundant

configure ports <primaryPort> redundant <secondaryPort> {link [on | off]}
Description
Configures a software-controlled redundant port.
Syntax Description
primaryPort Specifies one primary port or slot and port.
redundantPort Specifies one or redundant port or slot and port.
link Specifies state of link:
• on—Specifies keeping the redundant port active, but block traffic
• off—Specifies forcing the link down on the redundant port
NOTE: The default value is off.
Default
N/A.
Usage Guidelines
The first port specifies the primary port. The second port specifies the redundant port.
A software-controlled redundant port is configured to back up a specified primary port; both ports are
on the same device. The redundant port tracks the link state of the associated primary port, and if the
link on the primary port fails, the redundant port establishes a link and becomes active. You can back
up a specified Ethernet port with a redundant, dedicated Ethernet port.
You configure the redundant link to be always physically up but logically blocked or to be always
physically down. The default is off, or the redundant link is down.
The following criteria must be considered when configuring a software-controlled redundant port:
You can configure only one redundant port for each primary port.
●
You cannot have any Layer 2 protocols configured on any of the VLANs that are present on the
●
ports. (You will see an error message if you attempt to configure software redundant ports on ports
with VLANs running Layer 2 protocols.)
The primary and redundant port must have identical VLAN memberships.
●
The master port is the only port of a load-sharing group that can be configured as either a primary
●
or redundant port. (The entire trunk must go down before the software-controlled redundant port
takes effect.)
Only one side of the link should be configured as redundant.
