TIME CHANGE 2007

Cisco Proactively Addresses
the U.S. DST Challenge

Cisco is taking a proactive approach to compliance of U.S. Daylight Savings Time (DST) changes. We are dedicated to ensuring that Cisco products in your network will continue to operate without impact through the DST date transition. As a result, Cisco has undertaken a company-wide initiative to supply documentation to identify how to update each product.

For more information, please contact your sales representative, partner, or dealer, or visit the page below:

technologies_tech_note09186a00807ca437.shtml

Note: The Energy Policy Act of 2005 (H.R.6.ENR), Section 110, changes the start date of Daylight Savings Time from the first Sunday of April to the second Sunday of March, and changes the end date from the last Sunday of October to the first Sunday of November.

New Reader Tips - UPDATE:
Create Macros for a Cisco Switch

Note: All tips published in the Cisco Technical Services Newsletter are reviewed by Cisco technical support engineers; however, the Cisco Technical Services Newsletter and Cisco cannot guarantee the accuracy or completeness of these tips.

You can create macros to run a series of commands on a Cisco switch. This can be handy if you're logged in to a remote device and want to change the configuration, but doing so will mean you lose management access part-way through. You can define a macro and run it; even though you lose management access part way through, the macro will continue to run.

To configure the macro:

  • Enter configuration mode
  • Use the command macro name
  • Enter the commands you want the macro to run
  • Finish with @

The example below shows how to change the management VLAN from 1 to 100. Removing the IP address from the current management VLAN will disconnect your telnet session, but the macro will still execute the rest of the commands.

config t
macro name Change-vlan
interface Vlan1
 no ip address
 shutdown
interface vlan100
 ip address 172.29.159.6 255.255.255.252
 no shutdown @

To run the macro:

macro global apply Change-vlan

-Graham Mundell, Telecom New Zealand, Weymouth, Auckland, New Zealand

Editor's Note: The above tip is specific to Catalyst IOS that runs on very specific switches (like the 2950) and is not a standard in the majority of the remaining IOS versions available. Please refer to the configuration guide below for more information:

CCIE Central - UPDATE:
Comprehensive CCIE Service Provider Written Exam Released

Cisco has recently completed a series of changes to the CCIE Service Provider (SP) track.

Specific exam topics can be found online in the CCIE SP written exam blueprint and CCIE SP lab exam blueprint.

In addition, four of the previously-available written exams are no longer being used to qualify a candidate for the lab exam. The remaining four, however, will continue to be available for recertification purposes.

The recertification exams include:

  • CCIE SP Cable Exam (#350-021)
  • CCIE SP Content Networking Exam (#350-026)
  • CCIE SP Optical Exam (#350-020)
  • CCIE SP WAN Switching Exam (#350-023)
