5 Troubleshooting
This chapter provides information for troubleshooting HP-UX VLANs. It addresses the following
topics:
• “Link-Level : Connectivity Test” (page 49)
• “NetTL Trace and Log of VLANs” (page 52)
• “Additional Information” (page 54)
• “Reporting Problems to HP” (page 54)
Link-Level : Connectivity Test
Test link-level communications between local and remote hosts using the nwmgr command. The
local interface should be a VPPA, that is, a PPA corresponding to a VLAN interface. The
destination MAC address is the MAC address of the remote interface. (This example assumes
the remote host is also an HP-UX host.)
