Hidden interfaces...?

Hello, do i need to worry about hidden interfaces and trunks? I been investigating a network latency issue on our 6400 v9 ltm. I came across certain VLAN members that belonged to trunks. None of the trunks or interfaces are listed (gui/physical). They are however "seen" via the [-j] switch. As stated they form part of the vlans and one of these hidden trunks are showing continuous packet drops.... The device has two of these hidden trunks one using 0.1 & 0.2 (hidden interfaces) and also 4.1 & 4.2 (hidden interfaces). The one using 4.1 & 2 is showing a steady increment to its pkts drop b vlan all show all -j b trunk show all -j b interface show all -j

 

Thanks

      thanks nitass. packet captures are part of my investigation. i am looking for technical information regarding the hidden interfaces and trunks. need to understand them before deciding what to do next in terms of their relevance.

      Contacted F5 support and was advised the packet drops required further diagnostics via EUD. Turns out technical information about these interfaces are not released. In my case the interfaces are connected to the switch board via network cable, so needs checking.
