AnyConnect ... not connected but connected

[Alar Pandis]

Hi! One interesting thing I noticed today -- AnyConnect (was connected some ... 8 hours) show no connection, but connection still there!

This can provide clues as to a fragmentation issue in the network. Consumer routers are particularly poor at packet fragmentation and reassembly.

Try a scaling set of pings to see if it fails at a certain size. For example, ping -l 500, ping -l 1000, ping -l 1500, ping -l 2000.

It is recommended that you configure a special group for users that experience fragmentation, and set the svc mtu for this group to 1200. This allows you to remediate users who experience this issue but not impact the broader user base.

Hi and thanks!

Now it does work ... 3 days already and from both sides seems to be OK, at least "disconnect" button is available. Only thing I see now is that clock stopped on AnyConnect tab (I mean connection time), it show 21:04:28. Hope it is just ... cosmetic issue.

More thanks, Alar.
