IBM System Networking RackSwitch G8124E

Layer 3 functionality: The switch includes Layer 3 functionality, which provides security and 

performance benefits as inter-VLAN traffic stays within the chassis. This switch also provides the 
full range of Layer 3 protocols from static routes for technologies such as Open Shortest Path 
First (OSPF) and Border Gateway Protocol (BGP) for enterprise customers. 

Seamless Interoperability : IBM switches interoperate seamlessly with other vendors' upstream 

switches. For more information, see Tolly Reports: Tolly Functionality and Certification: 
RackSwitch G8000 and G8124 and Cisco Catalyst Interoperability Evaluation. For more 
information, visit the following website:

Fault tolerance: These switches learn alternate routes automatically and perform faster 

convergence in the unlikely case of a link, switch, or power failure. The switch uses proven 
technologies, such as L2 trunk failover, advanced VLAN-based failover, VRRP, HotLink, Uplink 
Failure Detection (UFD), IGMP V3 snooping, and OSPF.

Converged fabric: The switch is designed to support CEE/DCB and connectivity to FCoE 

gateways. CEE helps enable clients to combine storage, messaging traffic, VoIP, video, and other 
data on a common data center Ethernet infrastructure. FCoE helps enable highly efficient block 
storage over Ethernet for consolidating server network connectivity. As a result, clients can deploy 
a single server interface for multiple data types, which can simplify both deployment and 
management of server network connectivity, while maintaining the high availability and 
robustness required for storage transactions.

Transparent networking capability : With a simple configuration change to Easy Connect mode, 

the RackSwitch G8124E becomes a transparent network device, invisible to the core, eliminating 
network administration concerns of Spanning Tree Protocol configuration/interoperability, VLAN 
assignments and avoids any possible loops.

By emulating a host NIC to the data center core, it accelerates the provisioning of VMs by 

eliminating the need to configure the typical access switch parameters.
