Creating an 8x Port: 12800 Series
For the 12800 switches, 8x DUOs are set up on the leaf modules as follows:
UHP Leaf (18 4x QDR ports): combine the 4X port on the bottom row with the 4X
port directly above it (for example, port 1 with port 10, port 2 with 11, port 3 with
port 12, etc.).
UHD Leaf (24 4x QDR ports): for ports 1 through 18, combine the 4X port on the
bottom row with the 4X port directly above it (for example, port 1 with port 10, port
2 with 11, port 3 with port 12, etc.). For ports 19 through 24 DUOs are made by
combing the ports sequentially (that is, port 19 and port 20, port 21 and port 22,
and port 23 and port 24).
Figure 1-51. 12800 Leaf Module 8x DUOs
For example, to combine ports 8 and 17 on UHP leaf 111 in a 12800-180 switch:
1. Log into the switch CLI with the login admin and password adminpass.
2. Enable port 8 with a command similar to:
ismPortSetWidth L111P08 7 -bounce.
and press Enter.
3. Enable port 17 using same command as above, changing the port number
(that is., L111P17).
4. At the switch, unplug and reinsert the cables to the physical ports. After
reinserting the first cable, the user has four (4) seconds to reinsert the
second cable associated with the 8x connection before the link begins
training.
