NimbostratusHidden 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
The one using 4.1 & 2 is showing a steady increment to its pkts drop
if the number is significant, you may try to run eud.

do you set partitions ?
- Mahmoud_Eldeeb_
if you have configured partion, go to read only partion, you will find everything is listed over thre
- dan_03_140075We don't have partitions

- dan_03_140075thanks 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.
- dan_03_140075Contacted 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.
