Configuring the Commands without a
Separate User Account
Starting with Dell Networking OS version 9.3(0.0), you can configure the PMUX mode CLI commands without
having to configure a new, separate user profile. The user profile you defined to access and log in to the
switch is sufficient to configure the PMUX mode commands.
The IOA PMUX Mode CLI Commands section lists the PMUX mode CLI commands that you can now
configure without a separate user account.
Virtual Link Trunking (VLT)
VLT allows physical links between two chassis to appear as a single virtual link to the network core. VLT
eliminates the requirement for Spanning Tree protocols by allowing link aggregation group (LAG)
terminations on two separate distribution or core switches, and by supporting a loop-free topology. VLT
provides Layer 2 multipathing, creating redundancy through increased bandwidth and enabling multiple
parallel paths between nodes and load-balancing traffic where alternative paths exist.
