Hi group,
When matching a protocol unknown to NBAR and we have only the port
numbers available, let's say UDP 65001-65002, a common solution is to
use the "ip nbar port-map custom-01 udp 65001 65002" command.
However, my understanding is that this command above is not enough,
i.e. this is just a port mapping and the the custom.pdlm still has to
be loaded. See:
http://www.cisco.com/warp/public/105/custompdlms.html.
In newer IOSes, however, there is no need for custom.pdlm, as we can
really "define" the custom protocol and even give it a different name:
"ip nbar custom-01 udp 65001 65002". See:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios124/124tcg/tqos_c/part_05/qsnbar5.htm
Bottom line, did anyone tried in practice the old style of letting
NBAR know some custom protocols? Am I missing something?
Best regards,
Mihai
