    RISC-Based Architecture. The module can operate in two modes; as a 24 port Ethernet traditional switch (using 802.1d standards) with a high speed backbone connection or as a Secure Fast Switch (SFS) with 24 Ethernet connections. Each port of the 9E423-24 can be configured to operate in the Full Duplex mode.

  • Page 8: Features

    Spanning Tree, RMON, and MIB support within a scalable RISC-Based architecture. Fast Packet Switching The 9E423-24 incorporates a hardware based switch design referred to as the SmartSwitch ASIC, a collection of custom ASICs designed specifically for high speed switching. Because all frame translation, address lookups, and forwarding decisions are performed in hardware, the 9E423-24 can obtain a throughput performance of greater than 750K pps.
  • Page 9 Management Information Base (MIB) Support The 9E423-24 provides MIB support including: • RMON (RFC-1271) • IETF MIB II (RFC-1213) • IETF Bridge MIB (RFC-1493) and a host of other Cabletron Enterprise MIBs. For a complete list of supported MIBs, refer to the release notes provided in the 9E423-24 package.

    Operation The SMB-10 is externalized from the chassis via an optional Ethernet Port Interface Module (EPIM) located on the front of the Environmental Module. Through an EPIM connection, full SNMP management of the MMAC-Plus is available side-band from user data. Modules which share the SMB-10 bus periodically send out loop-back packets to ensure the validity of SMB-10.
