Citrix SD-WAN Center Diagnostics utilities provide Ping, Traceroute, and Packet Capture feature to test and investigate connectivity issues on Citrix SD-WAN Center appliance. The diagnostic options in the Citrix SD-WAN Center dashboard control data collection.
To use the Diagnostics tool, navigate to Administration > Diagnostics.
You can ping any management IP address in the SD-WAN Center network using the Ping option.
Provide a valid IP address along with the number of ping counts (amount of times to send the ping request) and packet size (number of data bytes). Click Stop Ping to stop an ongoing ping search.
Use the Traceroute option to ensure that the IP addresses are reachable. You can traceroute any management IP address in the network by displaying the route and measuring transit delays of packets.
Enter a valid management IP address to trace route. Click Trace Route.
The traceroute result display maximum 30 hops.
Use the Packet Capture option to intercept the data packet that is traversing over the selected active interface present in the selected site.
Provide the following inputs for packet capture operation:
- Region - Select a region that is managed by the SD-WAN Center from the drop-down list.
- Site - Available sites in the selected region. Select a site from the drop-down list.
Interface - Active interfaces are available for packet capture in the selected site. Select an interface or add interfaces from the drop-down list. At least select one interface to trigger a packet capture.
The ability to run packet capture across all the interfaces at once helps to speed up the troubleshooting task.
- Duration(seconds) – Duration (in seconds) for how long the data have to be captured.
- Max # of packets to view - Maximum limit of packets to view in the packet capture result.
Capture Filter (Optional) - The optional Capture Filter field accepts a filter string that is used to determine which packets are captured. Packets are compared to the filter string and if the comparison result is true, then the packet is captured. If the filter is empty, then all packets are captured. For more information, see Capture Filters.
Following are some examples of this capture filter:
- Ether proto\ARP - Captures only ARP packets
- Ether proto\IP - Captures only IPv4 packets
- VLAN 100 - Captures only packets with a VLAN of 100\
- Host 10.40.10.20 - Captures only IPv4 packets to or from the host with the address 10.40.10.20
- Net 10.40.10.0 Mask 255.255.255.0 - Captures only IPv4 packets in the 10.40.10.0/24 subnet
- IP proto \ TCP - Captures only IPv4/TCP packets
- Port 80 - Captures only IP packets to or from port 80
- Port range 20–30 - Captures only IP packets to or from ports 20 through 30
- Host 10.40.10.20 and Port 80 and TCP - Captures only IP packets to or from TCP port 80 on the host 10.40.10.20
The maximum capture file size limit is up to 575 MB. Once the packet capture file reaches this size, packet capturing is stopped.
