show statistics connection egress-methods
• One connection tuple to represent the Client—Edge segment
• One connection tuple to represent the Edge—Core segment
In the show output, these two connection tuples appear as TUPLE and MATE. (See Table 3-93.) The
important information to view is the local and remote IP address of the connection tuple and not whether
it is marked as TUPLE or MATE.
Figure 3-1 Topology with Three Segments and Corresponding Connection Tuples
Because the WAAS device is transparent to both the client-end of the connection and the server-end of
the connection, the local IP address for a connection tuple depends on the segment in the end-to-end
topology.
For example, when WAAS intercepts a packet from the client, this packet enters the connection tuple
that represents the Client—Edge segment. On this tuple, the WAAS device appears to the client as
though it were the server: the local IP address in this connection tuple is the IP address of the server,
while the remote IP address in this connection tuple is that of the client. Similarly, when the Edge WAE
sends data to the client, the packet egresses from this connection tuple as though it were coming from
the server.
When WAAS sends a packet to the server, the packet egresses from the connection tuple that represents
the Edge—Core segment. On this tuple, the WAAS device appears to the server as though it were the
client: the local IP address in the connection tuple is the IP address of the client, while the remote IP
address in this connection tuple is that of the server. Similarly, when the Edge WAE intercepts a packet
from the Core WAE, the data in this connection tuple appears to be coming from the server.
Examples Table 3-93 describes the fields shown in the show tfo egress-methods connection command display.
