config ports redundant
ExtremeWare Software 7.0.0 Command Reference Guide 171
config ports redundant
config ports [<portlist> | <portid> | mgmt] redundant [<portlist> |
<portid>]
Description
Configures a software-controlled redundant port.
Syntax Description
Default
N/A.
Usage Guidelines
On a modular switch,
<portlist>
can be a list of slots and ports. On a stand-alone switch,
<portlist>
can be one or more port numbers. For a detailed explanation of port specification, see “Modular Switch
Numerical Ranges” or “Stand-alone Switch Numerical Ranges” in Chapter 1.
The first port list specifies the primary ports. The second port list specifies the redundant ports.
A software-controlled redundant port is configured to backup a specified primary port. 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 can also back up a load-shared group of Ethernet ports with a
set of load-shared redundant Ethernet ports. If a link in the active load-shared group fails, the entire
group fails over to the redundant group.
The following criteria must be considered when configuring a software-controlled redundant port:
• You must manually configure the primary and redundant ports identically in terms of VLANs, QoS
settings, access lists, and so on.
• Auto-negotiation must be enabled on both the primary and redundant port.
• You cannot configure hardware redundant ports (such as ports 49 and 50 on a Summit48i) as
software controlled redundant ports.
• Software redundant ports are supported on products that use the “i” chipset.
portlist Specifies one or more primary ports or slots and ports. On a modular switch, can be a list
of slots and ports. On a stand-alone switch, can be one or more port numbers. May be in
the form 1, 2, 3-5, 2:5, 2:6-2:8.
portid Specifies a primary port using the display string configured for the port. If this option is
used to identify the port, the redundant port must also be specified using a port id (display
string).
mgmt Specifies the management port as the primary port. Supported only for switches that
provide a management port.
portlist Specifies one or more redundant ports or slots and ports. On a modular switch, can be a
list of slots and ports. On a stand-alone switch, can be one or more port numbers. May
be in the form 1, 2, 3-5, 2:5, 2:6-2:8.
portid Specifies a redundant port using the display string configured for the port. This option
may be used to identify the redundant port of the primary port was specified using the
port id (display string).
