AS5400XM open port range

[Lukasz Kacprzynski]

Hi All,

During audit in my company network scan revealed lot of open ports on Cisco AS5400XM device. These are few TCP ranges:

2216-2383
2432-2755

2416-4383
4432-4755

6216-6383
6432-6755

9216-9383
9432-9755

We have few devices on on each device range is slightly different but pattern looks the same. Do you have any idea what for those ranges are used? I spent hours of googling but with no luck.

Regards,

Lukasz

Hi, you can check the the list of open ports on your AS with the command show control-plane host.

Is your AS directly reachable from the posrt scanner or is the AS protected by a firewall?

Can you describe a little bit more your scenario? What signalling protocol do you use?

Regards.
