Link Tracking
By default, all server-facing ports are tracked by the operational status of the uplink LAG. If the uplink LAG
goes down, the aggregator loses its connectivity and is no longer operational; all server-facing ports are
brought down after the specified defer-timer interval, which is 10 seconds by default. If you have configured
VLAN, you can reduce the defer time by changing the defer-timer value or remove it by using the no defer-
timer command.
NOTE: If installed servers do not have connectivity to a switch, check the Link Status LED of uplink ports
on the aggregator. If all LEDs are on, to ensure the LACP is correctly configured, check the LACP
configuration on the ToR switch that is connected to the aggregator .
Configuring VLANs
By default, in Standalone mode, all aggregator ports belong to all 4094 VLANs and are members of untagged
VLAN 1. To configure only the required VLANs on a port, use the CLI or CMC interface.
You can configure VLANs only on server ports. The uplink LAG will automatically get the VLANs, based on the
server ports VLAN configuration.
Uplink LAG
The untagged VLAN used for the uplink LAG is always the default VLAN.
Server-Facing LAGs
The tagged VLAN membership of a server-facing LAG is automatically configured based on the server-facing
ports that are members of the LAG.
The untagged VLAN of a server-facing LAG is configured based on the untagged VLAN to which the lowest
numbered server-facing port in the LAG belongs.
NOTE
: Dell Networking recommends configuring the same VLAN membership on all LAG member ports.
Where to Go From Here
You can customize the Aggregator for use in your data center network as necessary. To perform additional
switch configuration, 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.
