Do you need a 1Gb switch that increases your data center efficiency and capability? Designed for the c-Class BladeSystem enclosure, the HP 6125G Ethernet Blade Switch appeals to budget-conscious data centers that need 1Gb switching and routing with the resiliency of Intelligent Resilient Networking (IRF), stacking, and the stability of Comware. It is ideal for remote office applications, or wherever IPv6, full Layer 3 routing and distributed trunking are required for 1Gb applications.


Data Center Efficiency

  • HP 6125G Ethernet Blade Switch can be combined with other switches at the enclosure, rack or datacenter level into a single virtual switch and managed through a single IP address.
  • All network devices can be managed through Intelligent Management Center (IMC) providing comprehensive single pane provisioning of the entire network.
  • The HP Comware operating system provides a common level of features, service, and security levels from edge to core.

Features & Benefits:


  • Non blocking architecture
  • Wire speed switching and IPv4/IPv6 routing on all ports
  • Separate 10Gb Internal cross connect between switches
  • Combine up to 10 switches into a single virtual switch
  • RJ45 and SFP ports support 1Gb
  • Ports 1 and 2 can be used as 1Gb SFP uplinks or as 10Gb IRF connections
  • Mix any combination of HP 6125G and HP6125G/XG in a single IRF domain
  • Store and Forward Switching
  • Hardware-based wire-speed access control lists (ACLs)


  • Remote configuration and management through Web browser or CLI
  • Secure Web-based management through HTTPS
  • Standards based SNMP management via SNMPv1, v2c and v3
  • OOBM via Onboard Administrator
  • GUI Management via Intelligent Management Center
  • RJ45 console port
  • sFlow and RMON network monitoring
  • Manager and operator privilege levels
  • Command authorization via RADIUS
  • Complete session logging for problem resolution
  • LLDP Discovery protocol
  • IPv6 management
  • Dual flash images
  • Multiple configuration files
  • Syslog
  • Network Time Protocol (NTP)


  • IEEE 802.1X user authentication
  • MAC-based authentication with RADIUS server
  • Access Control Lists (ACLs)
  • Secure FTP
  • STP Root Guard
  • DHCP Protection from unauthorized DHCP servers
  • IP Source Guard
  • Dynamic ARP protection to prevent eavesdropping
  • Guest VLAN
  • Endpoint Admission Defense (EAD)
  • Secure management via SSHv2 and SNMPv3
  • Unicast Reverse Path Forwarding (URPF)

Layer 2 Switching

  • 32K MAC addresses
  • 4094 VLANs
  • IEEE 802.1ad QinQ VLANs
  • Jumbo packet support
  • GVRP VLAN Registration Protocol
  • Port Aggregation
  • Spanning Tree Protocol, PVST, MSTP, RSTP, STP Root Guard
  • Smart Link fast uplink failure recovery
  • IP Multicast Snooping and data-driven IGMP
  • Policy Based Routing

Layer 3 Routing

  • IPv4 routing protocols - static routes, RIP, OSPF and BGP
  • IPv6 routing protocols - static routes, RIPng, OSPFv3 and BGP+
  • IPv6 tunneling
  • IP Multicast - PIM-SSM, PIM-DM, PIM-SM, IGMP for IPv4 and IPv6
  • Equal-Cost Multipath (ECMP)
  • Policy-based routing
  • DHCP and DHCPv6 client
  • VRRP

Quality of Service (QoS)

  • Advanced classifier-based QoS - classifies traffic using multiple match criteria based on Layer 2, 3 and 4 information; applies QoS policies such as priority level and rate limit to selected traffic on a per-port or per-VLAN basis
  • Traffic policing - supports Committed Access Rate (CAR) and line rate
  • Powerful QoS feature - creates traffic classes based on access control lists (ACL), IEEE 802.1p precedence, IP, DSCP or Type of Service (ToS) precedence; supports filter, redirect, mirror or remark; supports the following congestion actions: strict priority (SP) queuing, weighted round robin (WRR), weighted fair queuing (WFQ), and weighted random early discard (WRED)
  • Storm restraint - allows limitation of broadcast, multicast, and unknown unicast traffic rate to cut down on unwanted broadcast traffic on the network

Resiliency and High Availability

  • Intelligent Resilient Framework (IRF) - Creates virtual resilient switching fabrics, where two or more switches perform as a single Layer 2 switch and Layer 3 router; Switches do not have to be co-located and can be part of a disaster recovery system; Servers or switches can be attached using standard LACP for automatic load balancing and high availability; Simplifies network operation by eliminating Spanning Tree, ECMP and VRRP
  • Device Link Detection Protocol (DLDP) - Monitors Link connectivity and shuts down ports at both ends if unidirectional traffic is detected
  • Rapid Ring Protection Protocol (RRPP) - Connects multiple switches in a high-performance ring using standard Ethernet technology; traffic can be rerouted around the ring in less than 50 ms upon failure
  • Smart Link - Allows 50 ms failover between links
  • Virtual Router Redundancy Protocol (VRRP)

Monitoring and Diagnostics

  • OAM (802.3ah) - Detects data link layer problems in the "last mile"; monitors link status between two devices
  • CFD (802.1ag) - Connectivity Fault Detection (CFD) provides L2 link OAM mechanism used for link connectivity detection and fault location Mirroring - Port mirroring enables traffic on a port to be simultaneously sent to a network analyzer for monitoring; Flow-based mirroring
  • sFlow
