NBG-460N forwards out through an interface.
See Appendix E on page 369 for commonly used services and port numbers.
Table 82 Bandwidth Management Priorities
PRIORITY LEVELS: TRAFFIC WITH A HIGHER PRIORITY GETS THROUGH FASTER
WHILE TRAFFIC WITH A LOWER PRIORITY IS DROPPED IF THE NETWORK IS
CONGESTED.
High Typically used for voice traffic or video that is especially sensitive to
jitter (jitter is the variations in delay).
Mid Typically used for “excellent effort” or better than best effort and
would include important business traffic that can tolerate some
delay.
Low This is typically used for non-critical “background” traffic such as
bulk transfers that are allowed but that should not affect other
applications and users.
