Now we can have a look at the interface details on the WAE:
Or we can have a look at the individual interfaces:
However even if we see no hits on the error counters, this does not mean that the setup is correct. A good test to know if the inline interface is working correctly is to configure an IP on the inline interface group, enable the build-in FTP server in WAAS (with inetd enable ftp) and to FTP data from the LAN and WAN to and from that IP.
Often you will see that there is a problem with one direction of flow, for example you can download to the local LAN at Mbps, but uploading is much slower. This is then a clear indication of a duplex or cabling problem.
If the speeds are what you expect, but there is still a problem with all connection then we should check if the connections are getting intercepted by the WAAS. A "sh stat conn" should reveal if this is the case or not.
If you are seeing connections, but they are all in pass-through then we should check what is happening to the connections. Sometimes a look at "show statistics auto-discovery" will reveal what is going on:
"SYN retransmission" means that something is dropping packets with our special TCP tag. "* found with our device id" means that there is some kind of routing loop. "No peer or asymmetric route:" means that we tagged the packet, but we did not see a tagged SYN-ACK in reply.
In general what I like to do is to capture traffic for a specific client to a specific server. We can do this for example for the client 10.1.2.3 to the server 10.3.2.1 on the LAN side with:
and on the WAN side with:
As the IP's of the server and client will appear without modification on the inline interfaces we can just filter for the IP. Then we use "-c 3" to only show the first three packets we see. We use "-X" to get the full contents of the packets. In there we need to search for the
