The Dell EMC Networking S3048-ON switch serves as the OOB management switch for the Ready Stack. A single switch is used because this connectivity is not considered critical for workload operations.

Configure the S3048-ON switch

Configure the Dell EMC Networking S3048-ON switch:

1. Using the RJ45 to serial cable included with your switch, connect one end to your workstation and the other end to the RS-232 console port of the switch, as shown in the following figure.

Figure 4.         Serial port

2. Using terminal emulation software, configure the COM port:

• 115200 baud rate
• No parity/no flow control
• 8 data bits/1 stop bit

3. When the connection is successful, enter configuration mode by running the following commands:

OS10# configure terminal

4. Configure the hostname and time zone, and set a username and password for EXEC mode by running the following commands:

OS10(config)# hostname SWOOB

SWOOB(config)# username <username> password <password> role sysadmin

SWOOB(config)# clock timezone <timezone, example CST -6 0>

5. Configure routing to your default gateway, and save the configuration by running the following commands:

SWOOB(config)# ip route 0.0.0.0/0 <core network gateway>

SWOOB(config)# do write

Configure the VLANs

This section describes how to configure the VLANs on the S3048-ON switch. The examples show how to configure each VLAN in the site survey.

Follow these steps:

1. Configure the OOB VLAN:

SWOOB(config)# interface vlan 100

SWOOB(conf-if-vl-100)# description “out-of-band VLAN”

SWOOB(conf-if-vl-100)# mtu 9216

SWOOB(conf-if-vl-100)# no shutdown

SWOOB(conf-if-vl-100)# exit

SWOOB(config)# do write

2. To verify that all the settings have been properly recorded, from enable mode, review the configuration by running the following command:

SWOOB# show running-config

Configure the management interface

Configure the ports that the management servers’ iDRAC cards are connected to on the switch. In this example, ports 1/1 to 1/3 are used for the management server’s iDRAC.

1. Run the following commands:

SWOOB(config)# interface range ethernet 1/1/1-1/1/3

SWOOB(conf-range-eth1/1/1-1/1/3)# no shutdown

SWOOB(conf-range-eth1/1/1-1/1/3)# no ip address

SWOOB(conf-range-eth1/1/1-1/1/3)# switchport access vlan 100

SWOOB(conf-range-eth1/1/1-1/1/3)# spanning-tree port type edge

SWOOB(conf-range-eth1/1/1-1/1/3)# mtu 9216

2. Verify that the ports are properly configured by running the following command:

SWOOB(conf-range-eth1/1/1-1/1/3)# show configuration

The following output is displayed for each port:

interface ethernet1/1/1

 no shutdown

 switchport access vlan 100

 mtu 9216

 flowcontrol receive on

 spanning-tree port type edge

Configure the port channel

The Dell EMC Networking S3048-ON switch connects to the network through the Dell EMC Networking S5248F-ON VLT domain using a port channel consisting of two 10 GbE ports on the Networking S3048-ON switch. Follow these steps to configure the port channel and then configure the ports for the port channel:

1. Configure the OOB VLAN on the switch by running the following commands:

SWOOB(config)# interface vlan 100

SWOOB(conf-if-vl-100)# description “out-of-band VLAN”

SWOOB(conf-if-vl-100)# no shutdown

SWOOB(conf-if-vl-100)# ip address 172.90.100.25/24

SWOOB(conf-if-vl-100)# mtu 9216

SWOOB(conf-if-vl-100)# exit

SWOOB(config)# do write

2. Create the port channel by running the following commands:

SWOOB(config)# interface port-channel 101

SWOOB(conf-if-po-101)# description “OOB uplink”

SWOOB(conf-if-po-101)# no shutdown

SWOOB(conf-if-po-101)# switchport mode trunk

SWOOB(conf-if-po-101)# switchport trunk allowed vlan 100

SWOOB(conf-if-po-101)# mtu 9216

SWOOB(conf-if-po-101)# exit

3. Configure the ports that will be used for the port channel by running the following commands:

SWOOB(config)# interface range ethernet 1/1/49-1/1/50

SWOOB(conf-range-eth1/1/49-1/1/50)# description “OOB uplink”

SWOOB(conf-range-eth1/1/49-1/1/50)# no shutdown

SWOOB(conf-range-eth1/1/49-1/1/50)# channel-group 101 mode active

SWOOB(conf-range-eth1/1/49-1/1/50)# mtu 9216

SWOOB(conf-range-eth1/1/49-1/1/50)# exit

4. Verify that the port channel to the S5248F-ON switch is up by running the following command:

SW00B# show interface port-channel summary
