InJuniper Networks Mist AI Wireless,dynamic packet capture (dPCAP)is tightly integrated with events to enable rapid, context-aware troubleshooting. When Mist detects a systemic issue—such as aDHCP server becoming unresponsive—it automatically generates asite-level eventbecause the problem impacts multiple devices within a site rather than a single client.
As shown in the exhibit, the event “DHCP is Unresponsive” lists multiple impacted devices and includes a timeline of contributing network events. This classification is critical: DHCP infrastructure failures are treated assite events, not client-specific or organization-wide events. When such a site event is triggered, Mist can automatically perform adynamic packet captureon the relevant access points to capture DHCP Discover, Offer, Request, and Acknowledgment (DORA) traffic in real time.
To access this packet capture, an administrator must:
Navigate to theimpacted siteidentified in the event.
Open thecorresponding site event(in this case, the DHCP unresponsive event).
Download theautomatically generated packet capture file, which can then be opened inWiresharkfor detailed protocol-level analysis.
The incorrect options are explained as follows:
Organization eventsprovide high-level visibility and auditing but do not host packet captures.
Client eventsare used when a single client experiences issues; they are not appropriate when multiple devices are impacted by a shared service failure.
Verifying an impacted client does not expose the dynamic packet capture tied to a site-wide DHCP issue.
Therefore, the correct method is toverify the impacted site and use the corresponding site event to fetch the automatically generated packet capture, makingOption Bthe correct answer.
