Assume that the figure below describes how you want to set up your data center.
Figure 114: Example data center
Assume that you are configuring the switch in the left-hand rack to communicate on both the data and
management networks. You might do the following:
• Configure an IP address on the data network.
• Verify that out-of-band management is enabled. (It is enabled by default.)
• Configure an IP address on the management network.
• Verify that the switch can communicate on both networks.
The CLI commands that follow would accomplish those tasks. (The first time through the process you might easily
make the omission shown near the end of the example.)
Switch 41# config
Switch 41(config)# vlan 1
Switch 41(vlan-1)# ip address 10.1.129.7/20 Set up IP address on data network.
Switch 41(vlan-1)# end Exit back to manager context.
Switch 41# show oobm Look at default OOBM configuration.
Global Configuration
OOBM Enabled : Yes
OOBM Port Type : 10/100TX
OOBM Interface Status : Up Defaults look appropriate.
OOBM Port : Enabled
OOBM Port Speed : Auto
Switch 41# config
Switch 41(config)# oobm Go to OOBM context and
Switch 41(oobm)# ip address 10.255.255.41/24 add IP address and
Switch 41(oobm)# ip default-gateway 10.255.255.1 default gateway.
Switch 41(oobm)# end Exit back to manager context.
Switch 41# ping 10.1.131.44 Ping server in this rack (on data network.)
10.1.131.44 is alive, time = 19 ms
Switch 41# ping 10.1.131.51 Ping server in adjacent rack.
10.1.131.51 is alive, time = 15 ms
Switch 41# ping 10.255.255.42 Ping switch in adjacent rack.
The destination address is unreachable. Oops! It’s on the management network.
Switch 41# ping source oobm 10.255.255.42 Go through the management port
10.255.255.42 is alive, time = 2 ms and it works fine.
