Description

Using version?? on 04.30.2012:

This issue was discussed on the InstaGENI maillists, entering ticket to track resolution.

In a scenario where a sliver is created without specifying the "capacity" value, the createsliver results in a mapper error. Following are the RSpec lines that cause the failure:

  <link client_id="insta1-and-insta2">
    <interface_ref client_id="insta1:if1"/>
    <interface_ref client_id="insta2:if1"/>
    <property source_id="insta1:if1" dest_id="insta2:if1"/>
    <property source_id="insta2:if1" dest_id="insta1:if1"/>
  </link>

The modified "property" lines that resolve the problem:

  <link client_id="insta1-and-insta2">
    <interface_ref client_id="insta1:if1"/>
    <interface_ref client_id="insta2:if1"/>
    <property capacity="1000000" source_id="insta1:if1" dest_id="insta2:if1"/>
    <property capacity="1000000" source_id="insta2:if1" dest_id="insta1:if1"/>
  </link>

The mapper failure reported when using the "property" without a bandwidth specified, is shown here:
