Features And Specifications - IBM G8124E Product Manual

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

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.
