Introduction

Product Overview

•Jumbo Frame support

—Large 9000 byte maximum transfer unit (MTU) for improved efﬁciency and performance with bulk data transfer

—Supported only at 1000Mbps interface (link partner must also support Jumbo Frames)

•SNMP (MIB-II) support

•MC/ServiceGuard and Auto-Port Aggregation (APA) support for high availability

Note: MC/ServiceGuard is not supported on HP-UX 11iv1.5. APA is not supported on HP-UX 11i v1.5 and 11i v1.6.

•Conﬁguration support through SAM

•Promiscuous mode (link and SAP) inbound and outbound support

•Supports TCP/IP, NFS, and DLPI applications. Ethernet and SNAP encapsulations are supported.

•Supports OLA/R (Online Addition and Replacement) (HP-UX 11i, PCI only)

Note that SX and T cards are not considered to be like cards for OLA/R, that is, you cannot replace an SX card with a T card, and vice versa.

HP does not support OLA/R on A6794A although HP-UX tools will allow the device to be suspended and resumed.

Performance on A6794A, A6847A, and A6825A

TCP performance is improved with better throughput on inbound and bidirectional trafﬁc and better request/response rate.

Differences Between gelan and igelan

The differences between gelan and igelan are:

•Supported platforms - see Table 1-1, “List of Gigabit Ethernet Products”.

•LED behavior - see Table C-1, “LED Description and Status for 1000Base-SX”and Table C-2, “LED Description and Status for 1000Base-T”.
