Description (partial)


After LC OIR, cHDLC MA's connection to L2VPN Mgr fails, and so cHDLC MA initialization never completes. This means that cHDLC interfaces will not come up.


This issue can only occur in the very rare case where a connection to L2VPN Mgr cannot be established, due a problem with sending messages in ENS. The condition is extremely rare (it has only ever been seen once, although the issue has been in 3 releases) - so is only likely to be hit if there is another more major problem on the router.

This issue exists in the following releases:
- R3.6
- R3.7
- R3.8
