The TL1 Browser is provided as a bean component in the API package which comes with AdventNet's Configuration Management Server. Some of the functions that can be performed through the TL1 Browser are: multiple command set and data set loading setting the parser options for a particular session support for sending messages as strings support for receiving partial TL1 messages 5 Network Management Using Telnet/CLI and TL1 Decoder Hex File Browse d a a 20 20 20 4e 4f 44 45 3 31 20 32 30 30 30 2d 31 3 Hex Data Decode 2 2d 30 36 20 32 32 3a 31 3 5 3a 34 33 d a 41 20 20 31 Decoded text : NODE01 2000-12-0622:15:43 A1 REPT DBCHG DATE=2000-12-06,TIME=22-15-43,SOURCE=0 D1,LINKID=RMT[192.168.20.106:1419],USERID =ADMIN,DBCHGSEQ=13:ENT-EQPT::SH1-SLOT- 1:0012" Clear Close Figure 5.5 Screenshot - Decoder window. support for debugging TL1 messages support for checking drop out connections support for receiving Autonomous messages. The TL1 Browser can be used to debug the messages transferred between the TL1 Browser and a TL1 device. The debug window can be used to check messages sent and received between the TL1 Browser and agent. The decoder translates hexadeci- mal messages into ASCII text. 5.6 Summary This chapter has introduced and given an overview of two major network manage- ment protocols: CLI and TL1. CLI is an old protocol but is still widely used. We have explained some of the measures that have been taken to allow CLI to remain in use for so long. The aim has been to allow the reader to understand the role of CLI and TL1, and also to have a basic technical understanding of these protocols. Finally, the functionality of modern network management OSS applications that supp
