PMUX Mode of the IO Aggregator
This chapter provides an overview of the PMUX mode.
I/O Aggregator (IOA) Programmable MUX (PMUX)
Mode
IOA PMUX is a mode that provides exibility of operation with added congurability. This involves creating multiple LAGs, conguring
VLANs on uplinks and the server side, conguring data center bridging (DCB) parameters, and so forth.
By default, IOA starts up in IOA Standalone mode. You can change to PMUX mode by executing the following commands and then
reloading the IOA. After the IOA reboots, the IOA operates in PMUX mode. PMUX mode supports both stacking and VLT operations.
Conguring and Changing to PMUX Mode
After the IOA is operational in the default Standalone mode:
1 Connect the terminal to the console port on the IOA to access the CLI and enter the following commands:
Login: username
Password: *****
Dell> enable
Dell#
Dell#show system stack-unit 0 iom-mode
Unit Boot-Mode Next-Boot
------------------------------------------------
0 standalone standalone
Dell#
2 Change IOA mode to PMUX mode.
Dell(conf)# stack-unit 0 iom-mode programmable-mux
Where stack-unit 0 denes the default stack-unit number.
3 Delete the startup conguration le.
Dell# delete startup-config
4 Reboot the IOA by entering the reload command.
Dell# reload
5 Repeat the above steps for each member of the IOA in PMUX mode.
After system is up, you can see the PMUX mode status:
Dell#sh system stack-unit 0 iom-mode
Unit Boot-Mode Next-Boot
-------------------------------------------------------
0 programmable-mux programmable-mux
Dell#
The IOA is now ready for PMUX operations.
