Page 4: Hardware Support
BLADE OS 5.1 Release Notes Hardware Support BLADEOS 5.1 software is supported only on the 1/10Gb Uplink Ethernet Switch Module (Figure 1) for IBM BladeCenter. The GbESM is a high performance Layer 2-3 embedded network switch that features tight integration with IBM BladeCenter management modules. - Page 5 If a DAC is not programmed to meet MSA specifications (including length identifier), the switch disables the port and generates a syslog message indicating that the DAC is not approved. The GbESM does not disable the SFP+ ports when using MSA-compliant DAC cables. For best...

Page 6: Updating The Switch Software Image
Place the new image onto a FTP or TFTP server on your network, or on a local computer. Transfer the new image to your switch. Select the new software image to be loaded into switch memory the next time the switch is reset. Loading New Software to Your Switch The switch can store up to two different software images, called image1 and image2, as well as boot software, called boot. - Page 7 Using the BLADEOS CLI At the Boot Options# prompt, enter: Boot Options# gtimg Enter the name of the switch software to be replaced: Enter name of switch software image to be replaced ["image1"/"image2"/"boot"]: <image> Enter the hostname or IP address of the FTP or TFTP server.
- Page 8 Once confirmed, the software will load into the switch. When loading is complete, use the following command in Global Configuration mode to select which software image (image1 or image2) you want to run in switch memory for the next reboot:...

Page 10: New And Updated Features
BLADEOS 5.1 for 1/10Gb Uplink Ethernet Switch Module (GbESM) has been updated to include new and enhanced features in support of server and peer switch discovery, as well as failure detection at the link layer. In addition, there are enhancements to existing implementations in the areas of dynamic routing protocols, configuration and reporting. - Page 11 BLADEOS 5.1 now supports IEEE 802.3ah Operation, Administration, and Maintenance (OAM) protocol. OAM allows the switch to detect faults on physical port links. Using OAM, if the Local Information that a port sends does not match the Remote Information received, the link is determined to be in an anomalous condition and is automatically disabled.

Page 12: Rate Limiting
Loopback interfaces can be of benefit in a number of protocols, improving access to a switch, as well as increasing its reliability, security, and scalability. In addition, loopback interfaces can add flexibility and simplify management, information gathering, and filtering. - Page 13 For LANs that have only two OSPF routing agents (the GbESM and one other device), specifying the interfaces as part of a point-to-point network allows the switch to significantly reduce the amount of routing information it must carry and manage, enhancing OSPF efficiency.
- Page 14 BLADEOS 5.1 includes multiple enhancements to the Layer 2 Failover feature to support advanced NIC teaming: In addition to the automatic monitoring triggers for trunk links, the switch software now supports new manual monitoring triggers. This allows you to define a list of ports and/or static or dynamic trunks to disable when a link failure thresdhold is reached on set of trigger ports and/or static or dynamic trunks.
- Page 15 ISL Layer 2 Protocol Enhancements BLADEOS 5.1 now supports additional Layer 2 protocols on Inter-Switch Link (ISL) ports: VRRP RSTP/MSTP 802.1Q VLAN Tagging 802.1p QoS/CoS 802.1X Port-Based Access Control ACLs STP Fast Uplink Bridge Priority With BLADEOS 5.1, the Fast Uplink Convergence bridge priority has been set to 65535.
- Page 16 BLADE OS 5.1 Release Notes Chassis Internal Network BLADEOS 5.1 now supports BladeCenter Chassis Internal Network (CIN). CIN provides internal connectivity between blade server ports and the internal Advanced Management Module (AMM) port. This allows blade server users to access the AMM via CLI, web-browser, or SNMP session, and allows the AMM to use services on the blades, such as LDAP, SMTP, DNS, and NTP.

Page 19: Supplemental Information
Supplemental Information This section provides additional information about configuring and operating the GbESM and BLADEOS. Management Module The “Fast POST=Disabled/Enabled” inside the IBM management module Web interface “I/O Module Admin Power/Restart” does not apply to the GbESM. Solution: To boot with Fast or Extended POST, go to the “I/O Module Admin/Power/Restart” window. - Page 20 If this does not work, use Solution 2 below. If you execute the /boot/reset CLI command on the GbESM or the GbESM resets itself, the management module might not push the IP attributes to the switch, and connectivity may be lost.

Page 21: Secure Shell (Ssh)
Gateway 4 STG 128 For more information about remotely managing the GbESM through the external ports, see “Accessing the Switch” in the BLADEOS 5.1 Application Guide. Note – The external uplink ports (EXTx) cannot be members of management VLANs. Secure Shell (SSH) Because SSH key generation is CPU intensive, the GbESM attempts to avoid unnecessary key generation. - Page 22 However, for the GbESM, there is a single configured facility value (0-7) used on all messages. By configuring a unique facility value for each switch, a single SYSLOG server can distinguish between the various GbESMs in the network. Refer to “System Host Log Configuration” in the BLADEOS 5.1 Command Reference.

Page 24: Link Aggregation Control Protocol
BLADE OS 5.1 Release Notes Link Aggregation Control Protocol If a static trunk on a GbESM is connected to another GbESM with LACP configured (but no active LACP trunk), the /info/l2/trunk command might erroneously report the static trunk as forwarding. Since LACP trunks use LACPDU packet to maintain trunking with the partner, there is a possibility for those packets to be dropped from an extremely busy trunk. -
