Chapter 1: Introduction

The IMUX function is configurable using the Network Tools command, imux, described in Chapter 4.

NOTE

Cabletron Systems products that support Inverse Multiplexing (IMUX), such as the HSIM-W87, HSIM-W6, CSX400, HSIM-W84, and HSIM-W85, must exist on both ends of the WAN link for the IMUX function to work. All bridging and switching functions, such as 802.1D, SecureFast VLAN, and 802.1Q are able to run as normal on the host platform when using the IMUX function on the HSIM-W87.

1.4.4Priority Queuing

WAN IP Priority Queuing is used to prioritize IP packets from a specified IP address. This prioritization ensures that certain packets get through the network, such as management packets which are necessary to the operation of the network, and routers that depend on protocols with tight timing, such as RIP, do not time out. The prioritized packets do not eliminate other traffic on the network, but are held in a special queue, so that they are not discarded during oversubscribed traffic peaks. Priority Queuing can be enabled in management, using Network Tools. Refer to the wanpq command in the Management chapter.

1.4.5DS1 Alarm

Using the DS1 Error Threshold Alarm Monitor provides a means of setting error thresholds and notifying the user of potential DS1 problems with SNMP trap events.

The ds1alarm Monitor feature can be enabled in management, using Network Tools. Refer to the ds1alarm command in the Management chapter.

1.4.6SNMP and MIB Support

With the SNMP support, the MIBs supported by the HSIM-W87 include:

RFC 1406 – Definitions of Managed Objects for the DS1 and E1 Interface Types

RFC 1407 – Definitions of Managed Objects for the DS3/E3 Interface Type
