Extreme VLAN <-> IP-Address Matching Issue

Details

    Description

      After upgrading to a new version of EXOS we figured out that Observium is creating two port interfaces for a VLAN which has a IP configuration on it. 1st without rtif has the lower port_id and the 2nd with rtif and IP information has the uppert port_id in database. Everytime this is the case. Maybe this information help you.

      Attached two screenshots to demonstrate you the issue and a SNMP output from the interface/vlan which is visible in the screenshots.

      The best case would be if you remove everything behind the VLAN name i.e. "rtif(x.x.x.x/y)".
      The rtif string sucks a lot.

          Hi all,

          I think that this can be improved by using the extremeVlan MIB. Physical interfaces can be dedected as usual and for VLAN and IPv4 information on those it can be done with this.

          Finally the rtif() interfaces could be ignored by Observium and/or ignored by user configuration in config.php.

          • extremeVlanIfDescr (1.3.6.1.4.1.1916.1.2.1.2.1.2) will give you the VLAN names
          • extremeVlanIpNetAddress (1.3.6.1.4.1.1916.1.2.4.1.1.1) will give you the VLAN IP addresses
          • extremeVlanIpNetMask (1.3.6.1.4.1.1916.1.2.4.1.1.2) will give you the VLAN IP subnet masks

          Tested against XOS 22.4.1.4 and 16.2.4.5

          This is as Vendor report/store interfaces /vlan information in SNMP output..

          Not possible to do something here.
          rtif(x.x.x.x/y) is common names for Extreme, and if vlan not have name, than only rtif will displayed.

          Observium is not "creating" anything. We only display what the device reports to us.

          This is a change of behaviour by XOS and nothing to do with us.
