1892.0. "DENMA - SLIP connection" by VNABRW::AVE1::wariwoda () Mon Jan 16 1995 05:38

Hi,

does the DENMA (DECagent 90) support management of HUBwatch via a SLIP connection on the 
console port. The DENMA with firmware V2.1.0 has the option 

		- switch to SLIP mode

in the configuration menu. 

What I want to do is connecting the console port of the DENMA to a DECserver90M and 
managing the DENMA using this SLIP connection. Does this work?

Additionally if I switch to SLIP mode the DENMA has to be reset for a terminal connection 
to the console port. Is it possible to make this SLIP connection permanent only 
reconfigured by a reset to factory defaults.


thanks in advance,
Rafael

1892.1SLIP works now!ROGER::GAUDETBecause the Earth is 2/3 waterMon Jan 16 1995 12:2910
Absolutely.  Managing a DECagent via HUBwatch over a SLIP connection on the
front panel DB25 works just fine.  However, with V2.1.3 you do need to do some
manual configuration of the port before establishing a SLIP connection.

Since V2.1.3, there was some work to make the SLIP configuration permanent and
to auto-sense a SLIP connection (thus eliminating the need to select it from the
setup menu).  I am not sure of the status of either of these efforts at this
time, but I will ask the responsible engineers to respond to this note.

1892.2SLIP works with V2.*NETCAD::WALTERMon Jan 16 1995 14:4732
    You can use SLIP over the Denma console port with V2.* code. Just   
    configure the server for SLIP mode on that port, setting the host
    IP address to the Denma's IP address. Resetting the Denma will cause
    the console to revert back to terminal mode.
    
    We are currently working on V3.0 of Denma code. The update is primarily
    to support the new stackable repeaters, but I have already revised
    SLIP operation so that once you put it in SLIP mode, it will stay there
    through normal resets. To go back to terminal mode, you can either
    reset-to-defaults or you can just press the button on the front panel
    AFTER the Denma has gone through its power up diagnostics (if you press  
    the button during the diags, it will effectively reset to defaults).
    Note that this change will appear when V3.0 code is released.
    
    Something worth pointing out about using SLIP on the Denma: the Denma
    has only 1 IP address, even though it really has two interfaces (the
    Ethernet port and the console port when in SLIP mode). It really should
    have a separate address for each interface, but the IP stack was not 
    designed to handle more than one address. This won't necessarily cause
    you any problems; it depends on how you are using the SLIP connection.
    Just remember that if the terminal server is on the same LAN as the 
    Denma, they BOTH will reply to ARP requests, although with different
    MAC addresses. If you are using the SLIP interface to manage the Denma
    out-of-band, then the terminal server shouldn't be on the same LAN in
    the first place (presumably that LAN is the one you are trying to fix
    or debug). If code space and schedule allow we will add the second
    IP address capability, but we are VERY low on code space, and this has
    a much lower priority than the rest of the update effort.
    
    Regards,
    Dave

Thanks for your replies

I put the terminal server on a different LAN because the SLIP connection should work in 
case of LAN partitioning.
