Figure 106. Trunk Wrapping in Active Per-Port Switching Module
8.12.2 Trunk Wrapping on the Active Module-Switching Modules
When, during the beacon recovery process, it is determined that the fault domain
is between RI and RO, the following process takes place:
1. DRA and URA are inserted on the primary path.
2. RI/RO trunk is treated like a single lobe port. If wrapping the trunk pair fixes
the fault, trunks are left wrapped.
3. URA and DRA are de-inserted.
4. DMM and Merge Manager (see 8.12.3, “Merge Manager” on page 170) are
notified of the action taken.
This is shown in Figure 107.
