IP Count Configuration367
Configuring IP Count on an interface can enable packet accounting on the 
interface. You can configure to make statistics on the packets input or output on 
the interface, as well as packets denied by firewall.
Perform the following configuration in interface view.
Ta b l e 400   Configure IP Count on an interface
By default, IP Count is not enabled on interfaces.

IP Count list is configured for the purpose of classifying the statistics made by IP...

368CHAPTER 23: CONFIGURING IP COUNT
The default max entries number of exterior is set to 0, namely, the packets that do 
not match the rules will not be counted.
5Configure Upper Threshold of Interior-List Accounting Entries
The following command is used for specifying count maximum of interior, that is, 
the max entries number of the packets compliant with the IP Count lists. 
Perform the following configuration in system view.
Ta b l e 403   Specify count maximum of interior
By default, the upper...

CONFIGURING IPX
This chapter contains information on the following topics:
■IPX Protocol Overview
■Configure IPX 
IPX Protocol OverviewNovell IPX protocol is a connectionless protocol. Though both data and destination 
IPX address are included in IPX packet, the protocol cannot confirm whether a 
packet has been forwarded successfully. Such functions are provided by the 
protocol at the layer above IPX. In IPX, any IPX packet is considered as an 
independent entity, not related to any other IPX...

372CHAPTER 24: CONFIGURING IPX
network routing information which can be sent to destination or needs to be 
forwarded, so that when a packet is received, the next router can be found to 
transmit the packet. The routing information here can be configured both 
statically and dynamically. In a router, collection and maintenance of dynamic 
routing information are realized by RIP.
RIP is an abbreviation for Routing Information Protocol. A router creates and 
maintains an inter-network routing information...

Perform the following task in interface view.
Ta b l e 407   Enable IPX interface
By default, IPX is disabled on all interfaces after being started.
Delete interface IPX, then IPX configuration is removed from the interface, static 
service information and static routing information will be deleted.
3Configure Relative Parameters of IPX RIP
aConfigure IPX static route
RIP is used by IPX to decide the best path. Though a routing protocol can 
refresh a routing table...

Configure IPX 375
Ta b l e 410   Configure RIP updating period
By default, the time interval for RIP updating period is adjusted to be 60 
seconds.
cConfigure aging period of IPX RIP
Perform the following task in system view.
Ta b l e 411   Configure RIP aging period
By default, the aging period of a routing table item is 3 times that of RIP 
updating period. In other words, if a routing table item is not updated after 3 
RIP updating periods, it will be deleted from the table, so will the 
corresponding...

376CHAPTER 24: CONFIGURING IPX
When the length of a route reserve queue is 1, the system only saves one route 
for a destination. If this unique route is faulty, it will be deleted by the system 
and there will be no route to the destination while searching for the substitute 
routes, resulting in huge loss of packets. When the length of a route reserve 
queue exceeds 1, if one route is deleted, it will be replaced with another one as 
soon as possible, so as to prevent huge loss of packets. However,...
