Product overview

The HP 6125G Ethernet Blade Switch is a cost-effective 1Gb blade switch designed exclusively for HP c-Class BladeSystem enclosures. It features 16 downlink server ports at 1Gb, up to 8 uplink ports at 1Gb, and up to 2 10Gb IRF stacking ports for network resilience. The switch delivers non-blocking, wire-speed switching with full Layer 3 routing capabilities supporting IPv4 and IPv6. Key features include Intelligent Resilient Fabric (IRF) stacking for combining up to 10 switches into a single virtual switch, advanced QoS with traffic policing, and comprehensive monitoring via OAM and DLDP. With 26 Gbps uplink bandwidth and 16 Gbps downlink bandwidth, it provides 1.5 million packets per second forwarding rate. The 6125G supports 32K MAC addresses, 4094 VLAN IDs, and jumbo frames up to 9220 bytes. Ideal for remote offices, clustering, and virtualized environments requiring distributed trunking and full Layer 3 routing at 1Gb speeds.

Frequently asked questions

What is the maximum number of switches that can be stacked using IRF?

Up to 10 HP 6125G and 6125G/XG switches can be combined into a single virtual switch using IRF technology. This can be done at the enclosure, rack, or entire network level, simplifying management and enabling seamless failover with sub-50ms recovery via RRPP.

Does the 6125G support Layer 3 routing?

Yes, the 6125G provides full Layer 3 routing capabilities for both IPv4 and IPv6 with wire-speed performance on all ports. This eliminates the need for separate routing appliances in remote offices and clustered environments, reducing infrastructure costs.

What is the forwarding performance of the 6125G?

The switch delivers 1.5 million packets per second (pps) per Gigabit port and 14.8 million pps per 10Gb port using 64-byte packets. It features non-blocking, full wire-speed architecture with store-and-forward forwarding mode for all connections.

Can the 6125G be used outside of BladeSystem enclosures?

No, the HP 6125G is designed exclusively as a blade switch for HP c-Class BladeSystem enclosures. It functions as a plug-in module within the enclosure and cannot operate as a standalone switch.

What QoS features are supported?

The 6125G supports comprehensive QoS including traffic classification via ACLs, IEEE 802.1p precedence, DSCP, and ToS values. Features include Committed Access Rate (CAR) traffic policing, filtering, redirection, mirroring, and remarking capabilities for granular traffic management.

How many VLANs and MAC addresses does the switch support?

The 6125G supports 4094 VLAN IDs and 32K MAC addresses per switch in a BladeSystem enclosure. It also supports 1024 IGMP groups for multicast applications and jumbo frames up to 9220 bytes.

What is the power consumption of the 6125G?

The HP 6125G consumes only 26W of power, making it highly efficient for blade enclosure deployments. This low power consumption minimizes operational costs and heat generation while maintaining enterprise-grade performance and reliability.
