Deployment Guide

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 specied defer-timer interval, which is

10 seconds by default. If you have congured 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 congured, check the LACP conguration on the ToR switch that is connected to

the aggregator .

Conguring VLANs

By default, in Standalone mode, all aggregator ports belong to all 4094 VLANs and are members of untagged VLAN 1. To congure only the

required VLANs on a port, use the CLI or CMC interface.

You can congure VLANs only on server ports. The uplink LAG will automatically get the VLANs, based on the server ports VLAN

conguration.

When you congure VLANs on server-facing interfaces (ports from 1 to 32), you can assign VLANs to a port or a range of ports by

entering the vlan tagged or vlan untagged commands in Interface Conguration mode; for example:

Dell(conf)# interface range tengigabitethernet 0/2 - 4

Dell(conf-if-range-te-0/2-4)# vlan tagged 5,7,10-12

Dell(conf-if-range-te-0/2-4)# vlan untagged 3

Uplink LAG

The tagged VLAN membership of the uplink LAG is automatically congured based on the VLAN conguration of all server-facing ports

(ports from 1 to 32).

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 congured based on the server-facing ports that are members of

the LAG.

The untagged VLAN of a server-facing LAG is congured based on the untagged VLAN to which the lowest numbered server-facing port

in the LAG belongs.

NOTE

: Dell Networking recommends conguring 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 conguration, 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.
