130 Implementing Cisco InfiniBand on IBM BladeCenter
5. The final step on the 3012 is to save this configuration to NVRAM.
From the main page of the Element Manager, click Maintenance → Save Config to save
the configuration to NVRAM.
6. After saving the configuration of the 3012 to NVRAM per these instructions, we must now
configure the 4948. In this example, we connect the Ethernet gateway module port 4/1 to
the 4948 on port gi1/16.
Note that all of these steps might or might not be necessary in your environment. Contact
your network engineer if you are not sure about what you need to do for this to work.
Note that it is assumed that the VLAN interface has already been created and is
configured as desired for this lab. Just in case, Example 7-1 shows how to create and
configure the management interface for VLAN 88 for this chapter.
Example 7-1 Creating the management interface if not already done
! Assumes starting from enable mode, enter config mode
conf t
! Create the VLAN to be used
vlan 88
! Create and configure the management interface for this VLAN
int vlan 88
ip address 172.16.225.250 255.255.255.0
no shut
end
write
Note: As mentioned previously, all changes done through the GUI take effect
immediately and are placed in the running config, but the changes in the running config
are not explicitly saved to NVRAM until you perform this step.
Tip: Although we selected VLAN 88 for use for the port on the 4948 facing the gateway
module, this could have been any VLAN, including VLAN 1. VLAN 88 was just used as
an example for this section. Since the gateway is sending untagged packets, and we
will configure port gi1/16 for access mode, then only untagged packets will be sent
between the 4948 and the gateway module, and when the untagged packet is received
on port gi1/16, it will be placed on to VLAN 88 inside the 4948. What ever VLAN you
choose, it should be the correct VLAN for the IP subnet that is being used by the
InfiniBand clients.
