The tcpdump command exits immediately with an error: errbuf ERROR:TMM side closing: Aborted tcpdump: pcap_loop: TMM side closing: Aborted
Unable to capture the packets on specific tmm interfaces.
Capturing the packets on a tmm interfaces (0.x or <slot>/0.x).
Start tcpdump specifying TCPDUMP_ADDR to target the specific TMM that owns the internal interface. - On an appliance (BIG-IP appliance, vCMP guest on appliance, or rSeries tenant), use addresses of the form 127.1.1.<tmmnumber+1>, e.g. 127.1.1.1 for tmm0. - On a clustered system (VIPRION, vCMP guest on a VIPRION, or a VELOS tenant), use addresses of the form 127.20.<slot>.<tmmnumber+1>, e.g. 127.20.1.1 for slot1/tmm0 or 127.20.4.5 for slot4/tmm6. Use the platform-specific syntax below. On an appliance, omit the slot prefix. On a clustered system, retain the slot prefix: On an appliance: TCPDUMP_ADDR=127.1.1.16 tcpdump -w testcap.pcap -s 0 -i 0.16 On a clustered system: TCPDUMP_ADDR=127.20.2.1 tcpdump -w testcap.pcap -s 0 -i 2/0.1 Use a narrow capture filter and write the capture to a file where possible. BIG-IP tcpdump is best effort and may miss packets under load.
