In-Depth Information
If the router sees an address that matches an assigned SDLLC LAA address, it automatically forwards
that packet to the SDLLC process. This can result in packets being incorrectly forwarded to the SDLLC
process and sessions never being established.
To avoid assigning conflicting addresses, be certain that you know the LAA naming
convention used in the internetwork before assigning a virtual ring address for any SDLLC
implementation.
Note
SDLC: Sessions Fail over Router Running STUN
Symptom:
SDLC sessions between two nodes fail when they are attempted over a router that is running
serial tunnel (STUN).
This section discusses troubleshooting procedures for STUN without local
acknowledgment (LACK). For STUN with LACK, the procedures are essentially the same,
but remember that there are two sessions: one from the primary to the router, and one from
the secondary to the router.
