Default settings are in square brackets ’[]’
Would you like to enter the initial configuration dialog? [yes]
From this prompt, you can enter the initial configuration dialog or decline and manually enter the
configuration. This choice allows an administrator to use the Command Line Interface (CLI) on the
LightStream switch. If you are not familiar with configuring a LightStream switch, you may want to continue
using the System Configuration Dialog screen.
Supported Troubleshooting Protocols
LightStream switches support many protocols, such as Bootstrap Protocol (BOOTP) and Telnet, for remote
access to the switch and autoconfiguration. In−band management access is possible through the ATM
interfaces or the Ethernet port. Out−of−band management can be handled by the console port or either of the
two serial ports. One serial port allows a dedicated port to attach a local terminal, and one can be used to
attach an external modem for dial−in access through an analog telephone line.
Trivial File Transfer Protocol (TFTP) can be used for remote access to upload new firmware upgrades, save
configurations, or upload configurations.
Note Security for LightStream switches can be provided by the Cisco IOS software or a
Terminal Access Controller Access Control System Plus
(TACACS+)/authentication, authorization, and accounting (AAA). The Cisco IOS
can be configured with multiple password levels. A TACACS+/AAA server can be
used for remote access validation.
Snooping Mechanisms
Snooping mechanisms used by the LightStream 1010’s ports allow a mirrored connection from one or more
ports to be mirrored to another port. As a result, any data on a selected mirrored port will be copied and sent to
the mirror port. This process is completely transparent to the end devices connected to the port or ports being
monitored, and the data can be analyzed by an external ATM analyzer attached to the mirrored port.
Snooping mechanisms are one of the most important monitoring and troubleshooting tools used in ATM
switches. ATM analyzers can be used to monitor the traffic flows in and out of the selected ports. No external
devices can be connected to monitored ports to easily identify problems associated with ATM.
Multiprotocol Over ATM
Multiprotocol Over ATM (MPOA) enables the fast routing of internetwork−layer packets across a
nonbroadcast, multiaccess (NBMA) network. MPOA replaces multihop routing with point−to−point routing
using a direct VCC between ingress and egress edge devices or hosts.
Two components will be discussed here:
MPOA Server (MPS)• MPOA Client (MPC)•
The MPS
The MPS supplies the forwarding information used by MPCs. Once the MPS receives a query from a client, it
responds with forwarding information. MPOA uses Next Hop Resolution Protocol (NHRP) to support the
query and response. The MPS on the router can also terminate shortcuts.
Although, a router is usually designated as an MPS, it can also be designated as an MPC.
