CTM (Backplane) Interface Numbering Scheme
Read through the following section to learn about the CTM interface numbering scheme used by the
9A686-04 and 9A656-04. An understanding of this numbering scheme is necessary to create a PVC
across the CTM backplane.
Table 4 through Table 7 provide examples of how the CTM interface numbering scheme works,
depending on when the user has a 9A656-04 or 9A686-04, and if these modules are installed in a 14-slot
or 6-slot SmartSwitch 9500 chassis.
Refer to Creating a PVC across the CTM Backplane on page 10 for an example of how a user would use
the CTM backplane interface numbering scheme to create a PVC that traverses the CTM backplane.
