Issue/Introduction

Why are there host names missing from the admin tower, when running a "list clients" command?

Environment

Release:
Component: PPMPRD

Resolution

There are multiple factors that may cause this issue. In some cases, when Virtual LAN's are being utilized, it may be network related. For this particular document, Internet Group Management Protocol (IGMP) Snooping and Protocol Independent Multicast (PIM) Sparse modes need to be enabled in order for all corresponding host names to be listed in the admin tower.
