Link Aggregation
All uplink ports are configured in a single LAG (LAG 128). Server-facing ports are auto-configured as part of link aggregation
groups if the corresponding server is configured for LACP-based network interface controller (NIC) teaming. Static LAGs are
not supported.
NOTE: The recommended LACP timeout is Long-Timeout mode.
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.
For local management using the CLI, use the attached console connection.
For remote in-band management from a network management station, enter the IP address of the default VLAN and log in to
the switch to access the CLI.
In case of a Dell upgrade, you can check to see that an Aggregator is running the latest Dell version by entering the show
versioncommand. To download Dell version, go to http://support.dell.com
