As with many Data Centers we’ve been deploying a large number of blade servers and switches. We’re primarily an HP shop from a server,desktop and laptop perspective and we’ve been working with HP Blade System for the past two years.
HP actually OEM’s two different GbE2 switches for their Blade enclosures. One is based off a Nortel (Blade Technologies) solution and the other is based off a Cisco solution. We’re using the Nortel version and we’ll be focusing on that hardware in this post. If your unfamiliar with the Alteon CLI your going to need a few minutes to catch on. It’s pretty simple but very different from either the Nortel CLI or the Cisco CLI. Another important point is that the enclosure can actually accommodate two HP GbE2 switches. There’s an “A” side and a “B” side. You only need an “A” side switch to provide connectivity for the servers that will be housed in the enclosure but for high-availability solutions you’ll definitely need two switches installed into the enclosure.
In the following post I’ll outline how to configure a HP GbE2 Switch Blade trunking both ports into a MultiLink trunk. We’ll only using one HP GbE2 switch for this example and ignore the “B” switch. You should console up to the HP GbE2 using a serial cable (straight thru cable 9600, 8, N 1). The default password is “admin”.
Set Admin password
We’ll start out by setting the administrator password on the switch.
Set IP Address
Next we’ll setup an IP address on one of the interfaces.
Set IP Default Gateway
Next we’ll setup a default gateway for the switch.
Create Trunk Interface
We’ll create a Multilink trunk interface (Etherchannel) utilizing ports 19 and 20. Switch ports 19-22 are GBIC interfaces which are populated by 1000BaseSX SFPs.
Enable 802.1q (tagging) on fiber uplinks
The external uplinks are ports 19 and 20. The internal crossconnect links between the two HP GbE2 switches are on ports 17 and 18. We need to enable 802.1q VLAN tagging on the uplink ports so we can bridge multiple VLANs across the uplinks.
I’m going to just provide the commands for the remaining ports and skip showing the enter text of the menu to help save on the length of this document.
Create VLAN 200 for management of the switch itself.
Spanning Tree Protocol (Disable STP on trunk uplinks)
Network Time Protocol
Set PVID on Uplink Ports
Remove VLAN 1 from Uplink Ports
Simple Network Management Protocol (SNMP)
Save Configuration & Apply Configuration
The most important part of this exercise is apply the changes we’ve made and saving the configuration. Unlike Cisco or even Nortel switches the changes we’ve made above don’t take affect until they are ‘applied’ to the switch with the “apply” command.
Hopefully that will give you a good idea of how to configure an HP GbE2 switch in a basic configuration.
