2-2 MPLS Module Installation and User Guide
Installing or Replacing an MPLS Module
Software and Hardware Version Requirements
MPLS modules are compatible with “ i ” -series MSM modules, Summit and “ i ” -series
I/O modules, and Packet over SONET (PoS) modules. For the most current list of I/O
and PoS modules supported for use with the MPLS module, consult your release notes.
Software support for the MPLS module is provided in an ExtremeWare technology
release , which is a software release that provides specialized hardware support or
additional functionality not found in the current mainstream ExtremeWare release.
The ExtremeWare technology release that supports the MPLS module includes multiple
software packages. One software package runs on the MSM module while another
package runs on each MPLS module. You must download the software packages
independently using the ExtremeWare
download image
command. Each software
package has an associated version number that you can display using the
show
version
command. As a recommendation (not a requirement), the MSM software
package and the MPLS module software package should be the same version. To
ensure compatibility, the MSM performs an automatic compatibility check before an
MPLS module is activated. If the versions of the software packages are incompatible,
the MPLS ports on the module will not come up and the
show slot
command will
indicate that the software on the MPLS module is incompatible with the MSM software.
You can also verify compatibility by comparing the version of the MSM software
package with the version of the MPLS module software package. The format of the
software version field of the ExtremeWare software version identifier has been extended
to support technology releases. The following example of the ExtremeWare software
version identifier illustrates the extended version format:
ExtremeWare Version 6.1.5 (Build 20) Project IP_SERV_TECH_REL v1.2.64
In this example, the technology release-specific version information Project
IP_SERV_TECH_REL v1.2.64 is added to the base ExtremeWare version identifier
ExtremeWare Version 6.1.5 (Build 20) to form the extended version identifier format. The
first field of the version identifier, ExtremeWare Version 6.1.5 (Build 20) , identifies the
ExtremeWare software version on which this technology release is based. The second
field in the extended version identifier,
Project IP_SERV_TECH_REL , is the name of the
technology release. The final field 1.2.64 , is a three-part number that identifies the
version of the technology release. In the example, the first part of the number, 1 , is the
extended major version number; the second part of the number, 2 , is the extended minor
version number; the third part of the number, 64 , is the extended build version number.
