In the example below, the bidirectional traffic is captured on the interface lag1.55 between the source 172.20.6.1 and 10.0.165.5:
NP7 Sniffer:
diagnose npu sniffer filter intf lag1.55
diagnose npu sniffer filter dir 2 <-- Dir has 3 options (0 – ingress, 1 – egress, 2- both) to capture both ingress and egress.
diagnose npu sniffer filter protocol 6
diagnose npu sniffer filter srcip 172.20.6.1
diagnose npu sniffer filter dstip 10.0.165.5
diagnose npu sniffer start
diagnose sniffer packet npudbg
If a capture on multiple interfaces is required for example lag1.55 and lag2.55:
diagnose npu sniffer filter selector 0 <-- This is the filter ID and only 4 can be created and used simultaneously from 0 to 4).
diagnose npu sniffer filter intf lag1.55
diagnose npu sniffer filter dir 2 <-- Dir has 3 options (0 – ingress, 1 – egress, 2- both) to capture both ingress and egress.
diagnose npu sniffer filter protocol 6
diagnose npu sniffer filter srcip 172.20.6.1
diagnose npu sniffer filter dstip 10.0.165.5
diagnose npu sniffer start
diagnose npu sniffer filter selector 1 <-- This is the filter ID and only 4 can be created and used simultaneously from 0 to 4).
diagnose npu sniffer filter intf lag2.55
diagnose npu sniffer filter dir 2 <-- Dir has 3 options (0 – ingress, 1 – egress, 2- both) to capture both ingress and egress.
diagnose npu sniffer filter protocol 6
diagnose npu sniffer filter srcip 172.20.6.1
diagnose npu sniffer filter dstip 10.0.165.5
diagnose npu sniffer start
diagnose sniffer packet npudbg
