961.0. "GIGAswitch/ATMs and LANE problem" by NNTPD::"[email protected]" (Youda Kopel) Mon Jun 02 1997 05:16

Hi There Guys ,

Can someone please advice on this one.....

The problem appears to be with the P-NNI.  That is, when the 
        GigaSwitch/ATM's are rebooted, the ATM level routing information is 
        exchanged between the switches OK.  At some later, undefined time, 
        the ATM reachable address information disappears from BOTH 
        switches.  (When this happens, LANE ceases to work predictably as 
        they are using just one of the switches for LES/LECS/BUS.)  To 
        restate, the problem is that all reachable addresses from the 
        remote switch(es) disappear from the local table, even though the 
        NNI link is apparently up (Yellow port LED, green MOD PHY's).  This 
        happens on all three switches.  I don't know if it happens 
        simultaneously.  When first observed, the switches had been up for 
        about 5 days.

	The work around is to manually configure static reachable address 
        prefixes on each switch for the other's addresses (or reboot the 
        switches)

	Firmware is 2.1.4 on two switches, third is 2.1.3, active hardware 
        is DAGGL-BA with DAGGS on the interswitch links.  There are 
        DAGGL-AA and DAGGL-BA in the switches but no ports on these are 
        currently being used.


	If someone has seen this before and know how to overcome this please
let me know URGENTLY....

I wish we had in the manual a SIMPLE EXAMPLE of how to set up ELAN across
number of GIGAswitch/ATMs and other vendor LECs....

Many Thanks in advance .

Do you need more information about how to set up our servers, or about how to
set up other vendors' LECs?

Hi,

When this condition occurs, could you type the following two commands on both
the DEC Switches and mail me the info ?

   snmp_show_all
   sig_qsaal_state
