QuestionQ209

Identify and Resolve LTM Device Issues

An application owner reports that an LTM device is delaying delivery of an HTTP application. The LTM device has two VLANs: an internal VLAN and an external VLAN. The application servers are on the internal VLAN. The virtual server and clients are on the external VLAN.

With appropriate filters applied, which solution most efficiently obtains packet captures to investigate the reported delivery delay?

  • A one capture on interface 0.0
  • B one capture on the internal interface
  • C one capture on the external interface
  • D one capture on the management interface
Explanation

An LTM virtual server is a full proxy, so diagnosing application-delivery delay requires visibility into both the client-side flow entering through the external VLAN and the server-side flow leaving through the internal VLAN. Interface 0.0 captures TMM traffic without limiting the capture to one physical interface; with specific filters, a single capture can therefore cover both traffic legs.
