SAP Router

The following subsections show a graphical representation of the main protocol packets and how to generate them.

First we need to perform some setup to import the packet classes:



In [1]:

    
from pysap.SAPRouter import *
from IPython.display import display

    p = SAPRouter(type=SAPRouter.SAPROUTER_ADMIN, adm_command=command)
    print(router_adm_commands[command])
    display(p.canvas_dump())

                 SAPRouterRouteHop(hostname="10.0.0.1", port=3200, password="S3cr3t")]
router_string_lens = map(len, map(str, router_string))

display(p.canvas_dump())
for x in router_string:
    display(x.canvas_dump())
