Clients unable to connect during business hours

You can use following Plan of action to capture traffic specific to client experiencing the issue and find the cause for the issue::

1) tmsh modify /sys db tm.rstcause.log value enable 2) tmsh modify /sys db tm.rstcause.pkt value enable

3) Capture the packets on LTM using the following commands.

tcpdump -ni 0.0:nnnp -s0 -w /var/tmp/.pcap

4) capture the packets on the client host experiencing the issue using wireshark.

NOTE: both step 3 and 4 should be performed simultaneously while client experiencing the issue

5) terminate the logs by using following commands. tmsh modify /sys db tm.rstcause.log value disable tmsh modify /sys db tm.rstcause.pkt value disable

By Analysing the Captures in wire-shark and LTM logs, you should be able to find the root cause for the issue
