Components

3Com Network Director configures devices that are capable of
performing complex application classification to identify traffic as
belonging to an application by creating classifier rules. These classifier
rules are equivalent to the classifier rules that make up the definition
in the wizard. Traffic that matches these classifier rules is also mapped
to the Business Critical service level. See
“3Com Network Director
Service Levels”
on
page 655
for definitions of the service levels used
by 3Com Network Director.
When you are configuring 3Com devices that are not capable of
complex application classification, 3Com Network Director configures
these devices to identify traffic with the Business Critical DiffServ
codepoint. Traffic that matches this classifier rule is also mapped to
the Business Critical service level.
■
Blocked Applications
— selecting an application for blocking causes
traffic identified as belonging to that application to be dropped. Not
all devices are capable of dropping application traffic. A device must
be capable of both complex application classification and of dropping
traffic as a result of classification in order to drop application traffic.
3Com Network Director configures such devices to identify traffic as
belonging to an application by creating classifier rules. These classifier
rules are equivalent to the classifier rules that make up the definition
in the wizard. Traffic that matches these classifier rules is mapped to
the Drop service level. See
“3Com Network Director Service Levels”
on
page 655
for definitions of the service levels used by 3Com Network
Director.
3Com Network Director imposes restrictions on the blocking of SNMP
traffic. In addition, there are various problems that may arise due to
selecting applications for blocking. For more information see
“Potential
Hazards of Blocking Application Traffic”
on
page 661
.
If you prioritize traffic to and from a server then that server will also be
able to use any applications that are blocked.
Application Field Values
Application traffic is identified by examining certain fields in the packets
to see if they contain specific values. If you wish to add an application
that is not present in the list you will need to know the appropriate field
values required for that application.
