Standards-Version: 3.9.1
Package: openvswitch-datapath-source
.
Open vSwitch is a full-featured software-based Ethernet switch.
-Package: openvswitch-switchui
-Architecture: any
-Recommends: openvswitch-switch
-Depends: ${shlibs:Depends}, ${misc:Depends}, console-tools
-Description: Monitoring utility for OpenFlow switches
- The ovs-switchui utility included in this package provides a
- "front-panel display" to allow administrators to view the status of
- an OpenFlow switch at a glance.
- .
- The ezio-term utility, also included, provides a VT100-compatible
- terminal interface for EZIO3 (aka MTB-134) 16x2 LCD displays found on
- server appliances made by Portwell. It allows ovs-switchui to work
- with such displays.
