Utilities
The Utilities instrument provides network diagnostic tools and packet capture capabilities for troubleshooting connectivity and analyzing network traffic.
Note: In cluster deployments, a Cluster Node field is displayed in applicable scaffolds to indicate which node the entry belongs to.
Ping
The Ping utility allows the operator to send ICMP echo requests to test connectivity to a target host.
Enter an IP address or hostname in the Target field and click Ping to execute the test. The results will display in the Result text area, showing the round-trip time for each ping packet and summary statistics including packet loss percentage and average latency.
This tool is useful for quickly verifying network connectivity to upstream providers, DNS servers, or any host reachable from the rXg.
Traceroute
The Traceroute utility displays the network path taken by packets from the rXg to a destination host.
Enter an IP address or hostname in the Target field. Optionally check resolve DNS to display hostnames for each hop instead of just IP addresses. Click Traceroute to execute the test.
The results show each router hop along the path to the destination, including the IP address (or hostname if DNS resolution is enabled) and round-trip time for each hop. This tool is invaluable for diagnosing routing problems and identifying where packet loss or latency is occurring in the network path.
Ping Targets
The Ping Targets scaffold configures persistent ping monitoring targets used to determine uplink availability and network health.
The Cluster Node field shows which node in a cluster the ping target belongs to. The Name field is an arbitrary descriptor for administrative identification. The Online field displays the current status of the ping target based on recent ping results. The Target field specifies the IP address or hostname to ping. The Updated At field shows when the ping target status was last updated.
The Uplinks field associates the ping target with specific uplinks for failover monitoring. The Interfaces field allows association with specific interfaces. The Access Points and Access Point Radios fields enable client experience monitoring from wireless access points.
Tolerance thresholds define acceptable network quality: RTT Tolerance sets the maximum acceptable round-trip time in milliseconds. Jitter Tolerance sets the maximum acceptable variation in latency. Packet Loss Tolerance sets the maximum acceptable percentage of lost packets.
The WLAN field specifies a wireless network for client experience ping tests. The FOM Configurable field indicates whether the ping target can be configured through the Fleet Operations Manager.
When creating or editing a ping target, additional configuration options are available: Timeout sets how many seconds to wait for a response. Attempts specifies the number of ping packets to send per monitoring cycle. Interval sets the time between ping packets. Check SPAN enables SPAN port monitoring. Note provides space for administrative comments.
Tcpdumps
The Tcpdumps scaffold allows operators to capture network traffic for analysis and troubleshooting.
The Capture Behavior field determines how the capture is handled: Store to file saves the capture to disk for later download, while Stream to browser provides real-time packet viewing.
The Cluster Node field shows which node in a cluster to capture from. The Interface field selects which network interface to capture traffic from. Alternatively, the VLAN field allows capturing on a specific VLAN. The Access Point Radio field enables remote packet capture from compatible wireless access points.
Capture limits can be set using Max Packets to stop after capturing a specific number of packets, or Max Time and Max Time Unit to stop after a duration.
The Host A field filters the capture to only include traffic involving a specific IP or MAC address. The Host B field adds a second host filter to capture traffic between two specific endpoints. The Port field filters to capture only traffic on a specific TCP/UDP port. The Filter field allows entering a custom tcpdump filter expression for advanced filtering.
Action links are provided to Show Packets for streaming captures, Download completed captures as pcap files for analysis in tools such as Wireshark, and Terminate running captures.
LDAP User Info
When LDAP domains are configured, the LDAP User Info utility allows operators to look up user information from the LDAP directory.
Enter a Username and select the LDAP Domain to query, then click Lookup. The results display the LDAP attributes associated with the user account, including group memberships and other directory information.
This tool is useful for verifying that LDAP integration is working correctly and for troubleshooting user authentication issues.
LDAP Authentication Test
When LDAP domains are configured, the LDAP Authentication Test utility allows operators to verify that user credentials are valid.
Enter a Username and Password, select the LDAP Domain, then click Authenticate. The result indicates whether authentication succeeded or failed, helping operators troubleshoot login problems and verify LDAP connectivity.
