8. Re-attach or bring up the links between the 3012 and the 4948 (step 8 on page 143).

7.5.3 Detailed steps to implement a trunked bridge group design
To implement a trunked bridge group design, follow these detailed steps:
1. Make sure the cables between the module and the upstream switch are either unplugged
or logically shut down. This is to insure we do not introduce any temporary spanning tree
loops which could disrupt network communications.
2. It is assumed that you are starting from scratch, so delete any bridge groups that might
exist from the previous examples.
3. Using the Element Manager, click Ethernet → Trunking as shown in Figure 7-15.
