Trying to determine how the CGN function balances sessions across a pool of public IPs. With my current config (se below), NAT'ing jumps wildly between public IPs. An "inside" hosts changes public IP per session. I expected this, but not at this level. On an "outside" server, I logged this. <SNIP> Mon, 05 Aug 2019 15:20:54 +0200 [ERROR] {"username":"REMOTE-PROBE","remote":"42.42.42.78} Mon, 05 Aug 2019 15:25:02 +0200 [ERROR] {"username":"REMOTE-PROBE","remote":"42.42.42.78} Mon, 05 Aug 2019 15:26:05 +0200 [ERROR] {"username":"REMOTE-PROBE","remote":"42.42.42.78} Mon, 05 Aug 2019 15:48:13 +0200 [ERROR] {"username":"REMOTE-PROBE","remote":"42.42.42.79} Mon, 05 Aug 2019 15:57:04 +0200 [ERROR] {"username":"REMOTE-PROBE","remote":"42.42.42.78} Mon, 05 Aug 2019 15:59:06 +0200 [ERROR] {"username":"REMOTE-PROBE","remote":"42.42.42.79} Mon, 05 Aug 2019 15:59:13 +0200 [ERROR] {"username":"REMOTE-PROBE","remote":"42.42.42.78} Mon, 05 Aug 2019 16:02:25 +0200 [ERROR] {"username":"REMOTE-PROBE","remote":"42.42.42.79} Mon, 05 Aug 2019 16:03:44 +0200 [ERROR] {"username":"REMOTE-PROBE","remote":"42.42.42.78} Mon, 05 Aug 2019 16:03:53 +0200 [ERROR] {"username":"REMOTE-PROBE","remote":"42.42.42.79} Mon, 05 Aug 2019 16:13:52 +0200 [ERROR] {"username":"REMOTE-PROBE","remote":"42.42.42.79} Mon, 05 Aug 2019 16:21:55 +0200 [ERROR] {"username":"REMOTE-PROBE","remote":"42.42.42.78} Tue, 06 Aug 2019 08:30:44 +0200 [ERROR] {"username":"REMOTE-PROBE","remote":"42.42.42.79} Tue, 06 Aug 2019 08:59:15 +0200 [ERROR] {"username":"REMOTE-PROBE","remote":"42.42.42.64} </SNIP> The NAT-function works fine, but I would like some more "stickyness".

Wireshark locally on the switch is not possible. The switch is inaccessible. I don't believe that RSPAN supports encapsulation replication. At least not on the IE3000

That would require me to define all VLANs, which may be to much for the IE3000. It supports only 1005. A debug telling me that a packet have been dropped because the VLAN is not defined - would be the way...

Currently, i have an Cisco IE3000 switch, with an interface defined as a trunk. The other end is unknown to me, but I know it transmits tagged frames. I just don't know which VLAN-ids are in use - so I was thinking on doing some debugs to learn the VLAN-ids. Remote end does not transmit BPDUs

No. It's only possible to run a 1Gb sfp on the 3750ME's ES ports.
