if-index differences

Hi,

Can someone please help?

Should the configuration of both halves of a F5 HA cluster have the same if-index value when I look at the running configuration?

Some network statements (see below) are identical on both halves, others have a differing if-index values

net vlan VLAN888 {

  if-index 960

  interfaces {

    Core_Net {

      tag-mode service

      tagged

    }

  }

  tag 888

}

Is this an issue for the networks where there is a difference?

net config elements are part of base config, and are specific to the device - they are not synced. These elements need to match functionally between the members of a device group.

 

if-index is administrative, not functional, so there is no requirement to match. It just reflects that the elements were created in a different order between the members, and data can be accessed via different if-indexes using SNMP.
