What ports does the HP 6125XLG support?

It has 12 QSFP+ ports (each 40Gb native or 4x10Gb with breakout cable) and 8 SFP+ ports (1Gb or 10Gb depending on module). Includes dedicated 4x10Gb internal cross-connect ports and any port for IRF, providing 240Gb uplink and 160Gb server-side bandwidth.

What is the switching capacity?

Total 880Gbps switching capacity with non-blocking architecture, wire-speed IPv4/IPv6 routing, cut-through switching, and hardware ACLs. Delivers 14.8M pps per 10Gb port and 59.2M pps per 40Gb port for high-performance data center applications.

Does it support data center convergence protocols?

Yes, supports FCoE (NPV), TRILL, Data Center Bridging (DCB/DCBX), iSCSI, VEPA, OAM (802.3ah), and CFD (802.1ag), enabling lossless Ethernet for storage and network unification in blade environments.

What virtualization features are available?

IRF (Intelligent Resilient Framework) combines up to 4 switches (future 8) into a single virtual switch. Managed via HP Intelligent Management Center (IMC) with Comware v7 OS, supporting VLANs up to 4094 and jumbo frames to 10K bytes.

Yes, the 737230-B21 model is TAA (Trade Agreements Act) compliant, suitable for government and regulated deployments. Runs enterprise-grade Comware v7 with resiliency features like 2GB RAM, 512MB flash.

What management options does it offer?

Uses HP Comware v7 OS and IMC for centralized management. Supports SNMP, Telnet, SSHv2, RADIUS, TACACS+, sFlow, port mirroring, and IPv6 for comprehensive monitoring in enterprise networks.
