Chapter 3 Initial Configuration of the ML-Series Card
Cisco IOS on the ML-Series Card
During a soft reset, which reloads or warm restarts the ML-Series card, the ML- Series card checks the
cache for a Cisco IOS image. If a valid and current Cisco IOS image exists, the ML-Series card
decompresses and initializes the image. If the image does not exist, the ML-Series requests a new copy
of the Cisco IOS image from the 15310-CL-CTX or CTX2500. Caching the Cisco IOS image provides
a significant time savings when a soft reset is performed.
To use CTC to reset the ML-Series card with a hard reset or soft reset, at the CTC card-level view or
node-level view, right-click on the ML-Series card and click Hard-reset Card or Soft-reset Card. A
hard reset also requires that the ML-Series card is in the out of service (OOS) state, which is set under
the Inventory tab. Then click Yes at the confirmation dialog that appears. You can also initiate a hard
reset by removing and reinserting the ML-Series card. You can initiate a soft reset through Cisco IOS
with the privileged EXEC reboot command. For TL1 commands, refer to the Cisco ONS SONET TL1
Command Guide.
Caution A soft reset or a hard reset on the Cisco ONS 15310 ML-Series card is service-affecting.
There are four ways to access the ML-Series card Cisco IOS configuration. The two out -of-band options
are opening a Cisco IOS session on CTC and telnetting to the node IP Address and 2001. The
two-in-band signalling options are telnetting to a configured management interface and directly
connecting to the console port.
Opening a Cisco IOS Session Using CTC
Users can initiate a Cisco IOS CLI session for the ML-Series card using CTC. Click the IOS tab at the
card-level CTC view, then click the Open IOS Command Line Interface (CLI) button. A window
opens and a standard Cisco IOS CLI User EXEC command mode prompt appears.
Note A Cisco IOS startup configuration file must be loaded and the ML-Series card must be installed and
initialized prior to opening a Cisco IOS CLI session on CTC. See the “Startup Configuration File”
section on page 3-5 for more information.
Telnetting to the Node IP Address and Slot Number
Users can telnet to the Cisco IOS CLI using the IP addres s and the port number (2000 plus the slot
number).
Note A Cisco IOS startup configuration file must be loaded and the ML-Series card must be installed and
initialized prior to telnetting to the ML-Series card. See the “Startup Configuration File” section on
page 3-5 for more information.
Note If the ONS 15310 node is set up as a proxy server, where one ONS 15310 node in the ring acts as a
gateway network element (GNE) for the other nodes in the ring, telnetting over the GNE firewall to the
IP address and slot number of a non-GNE or end network element (ENE) requ ires the user’s Telnet client
to be SOCKS v5 aware (RFC 1928). Configure the Telnet client to recognize the GNE as the SOCKS v5
proxy for the Telnet session and to recognize the ENE as the host.
