3511.0. "90c mgt vis 90fs/Decagent ?" by LUX01::lxp215.bro.dec.com::triniane () Tue May 07 1996 05:18

Hello

Could you please help me to clarify the following point :

How can we manage 90c repeaters ? 
Those will be installed in stackable hubs where 90FS will be available. 
There will be also standalone Decagent available. 

When we read the "SPD" and doc of 90C. It is told that these are SNMP 
manageable via either a Decagent or a 90FS.

My current understanding of the "SNMP manageable" is not ok ?

. does it exist any differences between the management solution that would 
be based on the SNMP proxy used by the 90Fs and the other management 
solution that would be based on the Decagent. Do we get same functionality 
or does it exist differences between both solutions. Our current Hubwatch 
tests does not show any differences. 

. we did some tests using Hubwatch and Netview-NT, we are going ahead with 
additional tests but the current understanding is
. we can't get any counters related to the BNC ports.
. it seems that no trap mechaninsm exists and that the only way to discover 
a fault (partitioning) on a port is to pool the port (via the FS agent)  
. it seems that it exists no snmp variables related to the 90c.
. how could we get the list of stations residing on a 90c ports via Netview 
as Hubwtach is able to get them
. in Netview we don't see any MIB related to 90FS or 90C, however we see 
MIB for other type of equipements (like 90FA, 90FL...) and one generic 
Decrepeater...


thanks for your help

3511.1On/Off but no statsPTOJJD::DANZAKPittsburgher �Wed May 08 1996 22:4613
    I believe that the 90c (and 90t) when managed by an agent (read
    DECagent90 or 90TS or 90FS) will provide you only port status (is it
    on/off) and a connected station list.  Because the agent is providing
    PROXY for the repeaters, and SNMP values are DELTAS from the prior get,
    the agent doesn't have enough memory to provide stats on modules.
    
    So you get no stats!

3511.2trap / snmp variablesLUX01::lxp215.bro.dec.com::trinianeThu May 09 1996 09:4629
hello
>thanks for the info I have however still few questions

    I believe that the 90c (and 90t) when managed by an agent (read
    DECagent90 or 90TS or 90FS) will provide you only port status (is it
    on/off) and a connected station list.  

>is the port status send by a trap (link up, link down) or is it the result 
>of a pooling. 

	Because the agent is providing
    PROXY for the repeaters, and SNMP values are DELTAS from the prior get,
    the agent doesn't have enough memory to provide stats on modules.

>what do you mean by snmp values, which type of info can we get via 
snmp get...Is it describe in a document I can read/use

    
    So you get no stats!
    
    u c?

3511.3Not enough memoryPTOJJD::DANZAKPittsburgher �Thu May 09 1996 14:1318
    RE: .-1
    
    No, I dont' believe that you can trap port up/down etc.
    
    RE: Stats etc.
    
    I mean that stats that the agent (DECagent 90, 90TS or 90FS) gets from
    the module via whatever black magic that it uses.  The agent gets the
    values and doesn't have enough memory to store all the prior ones etc. 
    For example, if you took a Multistack with T16 repeaters stacked 14
    high you could get 154 ports!  That's a LOT of data for the itty bitty
    agent to store etc.
    
    hope that helps,
