Monitor packet duplication statistics for a device using Cisco SD-WAN Manager

Updated: April 24, 2026

Want to summarize with AI?

Configure monitoring of packet duplication statistics for network devices through the real-time monitoring interface.

This task enables you to view and analyze packet duplication counters for tunnel traffic on a specific device, helping you monitor network performance and troubleshoot connectivity issues.

Packet duplication statistics provide insights into tunnel packet handling, including original packets received, duplicate packets processed, and failed duplication attempts. These metrics are essential for monitoring network redundancy and tunnel performance.

Procedure

From the Cisco SD-WAN Manager menu, choose Monitor > Devices.

Choose a device.

For a device, in the Action column, click ... and choose Real Time.

In the Device Options drop-down menu, click Tunnel Packet Duplication Statistics.

The following table describes the packet duplication counters that appear in the Tunnel Packet Duplication Statistics pane:


Name of Counter	Description
pktdup-rx	Displays number of original packets received by primary tunnel.
pktdup-rx-other	Displays the number of duplicate packets received by this duplicate tunnel.
pktdup-rx-this	N/A
pktdup-rx-fwd	Displays the number of packets received and forwarded by this tunnel.
pktdup-rx-fwd-dup-tun	Displays the number of packets received and forwarded by the duplicate tunnel(s).
pktdup-tx	Displays the total number of duplicate packets generated with respect to this tunnel traffic which will be sent out on duplicate tunnel(s).
pktdup-tx-other	Displays the total number of duplicate packets sent out by this tunnel, but these packets belongs to some other original tunnel.
pktdup-tx-dup-tun-selection-failed	Displays the total number of failed duplication because duplicate tunnels are not available.
pktdup-tx-dup-tun-sent-failed	Displays the total number of duplicated packets failed to be sent out by duplicate tunnel(s).
pktdup-tx-intercepted	Displays the total number of packets which need to be duplicated with respect to this tunnel (equivalent to policy-match).
pktdup-capable	Indicates that this tunnel is capable of supporting the packet duplication functionality.

The tunnel packet duplication statistics are displayed with real-time counter values showing packet processing metrics for the selected device.
