A.2 Reset OS10EE switches to factory defaults
To reset OS10EE switches back to the factory default configuration, enter the following commands:
OS10# delete startup-configuration
Proceed to delete startup-configuration [yes/no(default)]:yes
OS10# reload
System configuration has been modified. Save? [yes/no]:no
Proceed to reboot the system? [confirm yes/no]:yes
The switch reboots with default configuration settings.
A.3 Factory default Cisco Nexus 3232C
To reset the Cisco Nexus 3232C switches to the factory default configuration, enter the following commands:
3232C# write erase
Warning: This command will erase the startup-configuration.
Do you wish to proceed anyway? (y/n) [n] y
After the next reboot the switch loads with default configuration settings.
A.4 Spanning Tree Protocol recommendations
By default, OS10EE uses Rapid per-VLAN Spanning Tree Plus (RPVST+) across all switching platforms
including PowerEdge MX networking IOMs. OS10EE also supports RSTP and MST.
Caution should be taken when connecting an RPVST+ to an existing RSTP environment. RPVST+ creates a
single topology per VLAN with the default VLAN, typically VLAN 1, for the Common Spanning Tree (CST) with
RSTP.
For non-native VLANs, all Bridge Protocol Data Unit (BPDU) traffic is tagged and forwarded by the upstream,
RSTP-enable switch, with the associated VLAN. These BPDUs use a protocol-specific multicast address. Any
other RPVST+ tree attached to the RSTP tree might processes these packets accordingly leading to the
potential of unexpected trees.
Note: When connecting to an existing environment that is not using RPVST+, Dell EMC Networking
recommends changing to the existing spanning tree protocol before connecting an OS10EE switch.
In the example below, RSTP is enabled globally on an MX9116n FSE. MST configuration is similar.
