- Another FYI:
-
- Our local telecommunication's recommended DECnet parameters were recently
- updated to have us use the following parameters:
-
-
- |For each Ethernet circuit (SVA-0, QNA-O, UNA-0, etc.)
- |
- |DEFINE CIRCUIT circuit-name HELLO TIMER 120
- |DEFINE CIRCUIT circuit-name ROUTER PRIORITY 64 ! or less
- |DEFINE CIRCUIT circuit-name MAXIMUM ROUTERS 64 ! or more
-
-
- I happily set these and went upon my business until the next cluster
- reboot when DECnet started but the ethernet devices on the cluster
- had an "Invalid parameter value" and failed to start. It seemed
- strange since it seemed these values were alright:
-
-
- |$ r sys$system:ncp
- |NCP>help set circuit maximum routers
- |
- |SET
- |
- | CIRCUIT
- |
- | MAXIMUM
- |
- | ROUTERS
- |
- | Applies only to Ethernet circuits. It specifies the maximum number
- | of routers (other than the executor itself) allowed on the circuit by
- | Routing for circuits that are owned by the executor node. The value
- | must be a decimal integer in the range 0 to 255.
- |
- |
- |Topic?
-
-
- Well it seems that the NCP HELP is wrong because the "VMS Network
- Control program" manual states that the permitted values for maximum
- routers is 0-33 (under SET/DEFINE CIRCUIT). When you try to SET
- this parameter above 33 you get an error:
-
-
- |NCP>set circuit sva-0 maximum routers 34
- |%NCP-W-INVPVA, Invalid parameter value , Maximum routers allowed
-
-
- however using the DEFINE command doesn't complain and in fact sets
- the parameter to an invalid value:
-
-
- |NCP>define circuit sva-0 maximum routers 64
- |NCP>list circuit sva-0 characteristics
- |
- |
- |Circuit Permanent Characteristics as of 10-SEP-1992 09:30:27
- |
- |Circuit = SVA-0
- |
- |Cost = 4
- |Maximum routers allowed = 64
-
-
- at which point you get the error upon DECnet startup and your
- ethernet devices are not activated.
-
- So... DON'T DEFINE MAXIMUM ROUTERS ABOVE 33!
-
- It would be nice if NCP HELP reflected reality and NCP not accept
- invalid parameter values which have bad consequences later.
