Cabling Procedure; Accessing The Cli; Configuring And Bringing Up A Stack - Dell PowerEdge M IO Aggregator Command Reference Manual

Cabling Procedure

The following cabling procedure uses the stacking topology in
1. Connect a 40GbE base port on the first Aggregator to a 40GbE base port on another Aggregator in the
same chassis.
2. Connect a 40GbE base port on the second Aggregator to a 40GbE port on the first Aggregator.
The resulting ring topology allows the entire stack to function as a single switch with resilient fail-over
capabilities. If you do not connect the last switch to the first switch (Step 4), the stack operates in a daisy
chain topology with less resiliency. Any failure in a non-edge stack unit causes a split stack.

Accessing the CLI

To configure a stack, you must access the stack master in one of the following ways:
• For remote out-of-band management (OOB), enter the OOB management interface IP address into a
Telnet or secure shell (SSH) client and log in to the switch using the user ID and password to access
the CLI.
• For local management, use the attached console connection to the master switch to log in to the CLI.
Console access to the stack CLI is available on the master only.
• For remote in-band management from a network management station, enter the virtual local area
network (VLAN) IP address of the management port and log in to the switch to access the CLI.

Configuring and Bringing Up a Stack

After you attach the 40G QSFP or direct attach cables in a stack of Aggregators, to bring up the stack,
follow these steps.
Note: The procedure uses command examples for the stacking topology in
Step Task
1 Set up a connection to the CLI on an Aggregator as described in
2 Log on to the CLI and enter Global Configuration mode.
3 Configure the Aggregator to operate in stacking mode.
4 Repeat Steps 1 to 3 on the second Aggregator in the stack.
5 Log on to the CLI and reboot each switch, one after
another, in as short a time as possible.
