Ta b l e 416   Configure IPX SAP updating period
By default, the updating period of IPX SAP is 1 tick (i.e. 1/18 seconds).
cConfigure SAP aging period
Perform the following task in system view.
Ta b l e 417   Configure SAP aging period
By default, the service information which is not updated in three update 
periods will be deleted.
If a service information table item is not updated after 3 updating periods, it 
will be deleted from the server information table.

378CHAPTER 24: CONFIGURING IPX
If the length of a service information reserve queue is 1, the system saves only 
one service information. If the server to which the only service information 
corresponds is faulty, system will delete this information, and you cannot find 
any server to provide such service while searching for the substitute service 
information. When the length of a service information reserve queue exceeds 
1, if one service information is deleted, it will be replaced with the next...

Configure IPX 379
Ta b l e 423   Configure the delay of interface sending IPX packets
By default, the delay of Ethernet interface is 1 tick, For asynchronous serial port is 
30 ticks and that for WAN port is 6 ticks. The range of ticks is: 0~30000.
8Configure Management of IPX Packet
By default, the router usually discards the broadcast packet of type 20, but you 
can also enable such packet to be sent to other network segments by configuring 
routers.

■DLSw Protocol Overview
■Configuration of DLSw 
■Display and Debug DLSw
■Typical DLSw Configuration Example
■Diagnosis and Troubleshooting of DLSw Fault
DLSw Protocol 
OverviewData Link Switch Protocol (DLSw) is a method designed by Advanced Peer-to-Peer 
Networking (APPN) Implementers Workshop (AIW) to load SNA through TCP/IP 
(SNA is a network protocol introduced by IBM in 1970s and completely 
correspondent with OSI...

■Create DLSw local peer entity
■Create DLSw remote end peer entity
■Configure Bridge set connecting to DLSw
■Configure to add Ethernet port to Bridge set
■Configure link layer protocol for interface encapsulation to be SDLC
■Configure SDLC role
■Configure SDLC virtual MAC address

Configuration of DLSw 385
Please perform the following configurations in system view.
Ta b l e 429   Create DLSw remote end peer entity
No DLSw remote end peer entity is created by default.
When creating remote backup-peer, note:
When the remote backup peer is created, the tcp ip-address should be the IP 
address of peer backup entity and the 
backup backup-peer-address should be 
the IP address of the remote master peer, which has established TCP connection. 
That is, the user should ensure that TCP...

386CHAPTER 25: CONFIGURING DLSW
Please process the following configurations in the Ethernet interface view.
Ta b l e 431   Configure to add ethernet port to Bridge set
No Ethernet port is added to Bridge set by default.
5Configure Link Layer Protocol for Interface Encapsulation as SDLC
SDLC is a link layer protocol relative to SNA. The working principle is very similar to 
HDLC. To allow DLSw to operate normally, the encapsulation protocol of 
synchronous interface link layer should be changed to SDLC....
