RE: Branches down. Any ideas? -- MIDRANGE-L

Jeff:
IF the APPC ctl/device are both active, then I would say that it is not a
router issue.  The vanguard routers do the spoofing locally before they pass
the XID over the WAN.  This is obviously happening.  If the Vanguard reports
that the HPAD is up, then they are happily passing SNA packets over the WAN.
If he varys off the APPC controller and device, he should see the HPAD /TPAD
drop in the routers.  Also weird that the RWC goes active.  Could this be a
mode issue.  The max sessions for the mode have been reached?  Weird that an
IPL did not "fix" the problem.

Seen this before, had to power cycle the Routers while the AS/400 line was
varied off.

This was because the routers were doing Spoofing (DLS) of the SNA/SDLC
connection and not all
the XID packets are being sent end to end, but rather most of the packets
never leave the building and once the pair get out of sequence they would
never recover even though they looked okay to the network ops guys..

Since, you describe a multiple configuration I would recommend powering all
of the routers down to clear the
hang condition in the network.

Good Luck,
JMS..
