QoS: 

•

 

Now, when a hardware encryption card (NDEC) is installed and QoS (Quality of 
Service) is enabled, the NDEC module will handle the QoS processing. 

 
 

The following features are included in this Release 

 

1.

 

Dynamic Routing Standby 

 

Dynamic routing standby is a new backup approach that mainly uses legacy DCC 

to dynamically maintain dial links. In other words, it is a route-based dial backup. 
 
By making use of convergence time and related features of dynamic routing 
protocols, dynamic routing standby perfectly combines backup and routing. Thus, it 
breaks the limitation of interesting packet-triggered dial in legacy DCC and provides 
reliable connection and standard dial-on-demand service. 
 
Dynamic routing standby is suitable for situations involving multiple interfaces and 
routers, since both primary and secondary interfaces can be of any interface type. 
Dynamic routing standby does not depend on a particular route protocol, and can run 
RIP1, RIP2, OSPF, etc. It does not depend on interesting packets to trigger dial, thus 
the secondary link will start automatically when the primary link disconnects without 
dialing delay (excluding route convergence time). 
 
You can configure and manage the dynamic routing standby feature using the 
following CLI commands: 
 

standby routing-group group-number 
undo standby routing-group group-number 
standby routing-rule group-number  ip ip-address address-mask  
Undo standby routing-rule group-number 
standby routing-check group-number timer seconds 
undo standby routing-check group-number 
standby routing-disable seconds 
undo standby routing-disable

X.25 CUG 

 

The X.25 protocol is the interface procedure between the data terminal equipment 
(DTE) and data circuit-terminating equipment (DCE). With X.25, two DTE devices 
can communicate with each other via the existing telephone network. DTE usually 
refers to the host or terminal at the user side and DCE usually refers to the 
synchronous modem.
