3562.0. "Can you exceed 248 days of uptime on DECswitch 900EF (v1.5)" by KAOT01::WATTERS () Mon May 27 1996 12:02

DECswitch 900EF (v1.5) and Gigaswitch(v ?) go GA-GA if uptime reaches
248 days. It appears, from what the customer tells me, that once it 
reaches the 248th day, the high order bit in the time counter is set.
When this happens, SNMP queries for time and expects to get a 4 byte integer
but gets a 5 byte integer. Rebooting the module fixes it.

BTW, using Hubwatch to connect to it he gets a 'system error' or 'general error'.


Is there a known problem w/ his version of firmware (at least on the DECswitch).

I'd appreciate any help on the matter.

3562.1Upgrade your DECswitch900EF to fw rev v1.5.2NETCAD::BATTERSBYDon't use time/words carelesslyTue May 28 1996 10:0514
    Andy, the current shipping rev of firmware for the DECswitch900EF
    has a "major" rev of 1.5.z and a "minor" rev of x.y.2  
    Thus when one looks at the console menu 3 of the DECswitch one will
    see fw=v1.5.2 for the rev, or in your possible case will be seeing
    rev fw=1.5.0  I only emphasis this as we have seen instances where 
    people shortcut the rev when describing it and perhaps confuse people 
    as to the real rev involved. Now if you really have a DECswitch
    with a rev of 1.5.0, then you should have it upgraded to the current
    shipping rev. The older rev you have in your DECswitch may be having 
    an affect on your ability to manage it. There are known problems with 
    v1.5.0 rev firmware, but they don't seem to fit your problem as you 
    describe it.

This is what's suppose to happen.  When counters exceed 0x7fffffff they
are also returned in 5 bytes.  This is specified in the SNMP protocol
documents.

This is a bug.  It will be fixed in the next release.

The firmware's doing the right thing in this case.

And by the way, it's nice to hear that our products stay up for 248 days.
I wish my workstation and PC could go that long without crashing.

    ...the same goes for the GIGAswitch/FDDI firmware - there's no problem
    with large uptimes for the GIGAswitch/FDDI firmware. The problem is
    just with those network management systems which have bugs.

Is the HUBwatch for VMS affected as well? 
If yes, what next release will fix the problem?

no.

OK, here it is... Current plans are to make an X4.1 version of HUBwatch for
OpenVMS available soon (I'm testing it now - Do not send mail or post notes
asking for it!!! I'll post a pointer when it's ready.).  There will NOT be a
released V4.1 version, nor will there be any future released versions of
HUBwatch for OpenVMS ever.

Because this is an X version, it will not be available through the SSB.
It is also largely unsupported.  But, people who absolutely positively
require it will be able to have it.

From what I've read, OpenVMS customers are being given some interesting
incentives to move to Windows/NT.  For more info, contact Jack NAC::Forrest.

no.

Just asking...
I have one customer, running DECmcc 4.0, HUBwatch/VMS 3.1. They have about 8 hubs (FW V3 - all 
modules). All 8 switches (FW 1.4) became unmanageable at the same time. We test the 
HUBwatch/Windows version (3.1) with the same result. After reboot (power cycle on the hub, not 
only restart of the switch), everything works fine.
