Since duplicate addresses can cause alot of problems in a network and with the proliferation of PCs/MACs and workstation on the network these is getting very serious. Alot of customers want to know if there are any ways in MCC to detect duplicate address for DECnet, OSI or TCP/IP? Can any other vendors' product do this? Raj Singapore

4649.1 | LANalyzers can do this | CUJO::HILL | Dan Hill-Net.Mgt.-Customer Resident | Thu Mar 11 1993 14:38 | 16 |
Network General's Sniffer can do this via the use of a timing algorithm. It assumes that a node will send out a hello message every 15 seconds. If it sees a hello packet outside this range (e.g., 12 seconds), then it assumes there is another node on the network with the same address. You can set a threshhold to give you more breathing room on very busy networks, though. I assume that HP will be able to do this soon, if not already, since their LAN monitoring utilities/hardware are getting better. DECmcc should be able to do this, also, but it doesn't. For those of you who desire such functionality, please continue to lobby for it. -dan | |||||
4649.2 | we can find something | UFHIS::WSIEGMUND | Seaboard riding on Seahorse | Fri Mar 12 1993 04:02 | 15 |
If you are looking for a doubble Decnet address do: $ mc ncp loop circuit sva-0 node 1.1 assistant node 1.1 This command is supposed to fail! If it ever succedes you will have at least two nodes using address 1.1 on your LAN. Of course you can also MCC> test node4 0 circuit..... I have not yet tried a similar MCC> test station .....
