n
User interface software that allows you to interface to the system in multiple
ways:
n
Through an RS-232 port for direct VT100 Connection. The CPU contains the
VT100 drivers to control the management and user interface screens.
n
Through a second RS-232 port to run SLIP/PPP. This port can connect via a
modem to the user management network. You can then run a Telnet
session to access the NMS screens.
n
Through the direct Ethernet connection. You can then run a Telnet session
to access the NMS screens.
n
SNMP support via the RS232 SLIP/PPP and the Ethernet connection. The
PathBuilder S600 supports multiple standard MIBs for the bridge, Ethernet and
DS3 functions. It also supports an Enterprise MIB that allows you to configure
and monitor the unit using an SNMP-based Enterprise management system
such as Transcend.
The CPU stores all the code that runs on the system and runs diagnostics at
bootup to check the integrity of the system.
SNMP MIB Standards Support
Table 20 lists the standards that are supported for the MIBs.
STX Module
The STX module provides a switching matrix that supports sophisticated traffic
management, priority queuing, and multicasting. It performs all functions
necessary for concentrating and switching ATM cells according to the set priority
given to its Class of Service traffic types:
n
Provides any-to-any switching based on VC address
n
Introduces Virtual Interfaces (VIs) which are logical UNI ports. Up to 24 VIs are
supported per module.
n
Supports Deep buffers (192,000 per module) for queuing to support 4 Classes
of Services per VI
n
Provides priority queuing in which each VC can be assigned to a specific VI
which then can be allocated to one of 4 queues for CBR, VBR-rt, VBR-nrt, and
UBR classes of service.
n
Supports Per VC and/or VP traffic shaping
n
Supports per VC traffic policing
n
Supports multicasting (up to 256 connections with 32 leaves)
n
Supports per VC statistics
n
Allows a total of 8,000 connections maximum per PathBuilder S600
