Server-Facing LAGs
The tagged VLAN membership of a server-facing LAG is automatically congured based on the server-facing ports that are
members of the LAG.
The untagged VLAN of a server-facing LAG is congured based on the untagged VLAN to which the lowest numbered server-facing
port in the LAG belongs.
NOTE: Dell Networking recommends that you congure the same VLAN membership on all LAG member ports.
Stacking Mode
When you congure an Aggregator to operate in stacking mode (See “Conguring and Bringing Up a Stack” in the Dell Networking
Conguration Guide for the M I/O Aggregator), VLANs are recongured as follows:
If an Aggregator port belonged to all 4094 VLANs in standalone mode (default), all VLAN membership is removed and the port is
assigned only to default VLAN 1. You must congure additional VLAN membership as necessary.
If you had manually congured an Aggregator port to belong to one or more VLANs (non-default) in standalone mode, the VLAN
conguration is retained in stacking mode only on the master switch.
When you recongure an Aggregator from stacking to standalone mode:
Aggregator ports that you manually congured for VLAN membership in stacking mode retain their VLAN conguration in standalone
mode.
To restore the default auto-VLAN mode of operation (in which all ports are members of all 4094 VLANs) on a port, enter the auto
vlan command:
Dell(conf)# interface tengigabitethernet 0/2
Dell(conf-if-te-0/2)# auto vlan
The auto vlan command is applicable only in Standalone mode.
To get the default standalone mode congurations:
1. Delete the startup-cong le and reboot the system.
2. Restore to factory default settings.
Where to Go From Here
You can customize the Aggregator for use in your data center network as necessary. To perform additional switch conguration, do
one of the following:
• For remote out-of-band management, enter the OOB management interface IP address into a Telnet or SSH client and log in to
the switch using the user ID and password to access the CLI.
• For local management using the CLI, use the attached console connection.
• For remote in-band management from a network management station, enter the VLAN IP address of the management port and
log in to the switch to access the CLI.
If you installed the Aggregator in a stack, you can congure additional settings for switch stacking
In case of a Dell Networking OS upgrade, you can check to see that an Aggregator is running the latest Dell Networking OS version
by entering the show version command. To download a Dell Networking OS version, go to http://support.dell.com.
Refer to the appropriate chapter for detailed information on how to congure specic software settings.
