LAN Lite,
SwitchesCisco Systems has recently announced the launch of the New LAN Lite switches that help small branches, small and medium-sized businesses, and others in space-constrained environments upgrade basic networks to fully managed networks.
So what is this LAN Lite?
LAN Lite is software which provides desktop Fast Ethernet connectivity for wiring closet and small branch-office networks to provide basic LAN services. The LAN Lite Cisco IOS Software provides entry-level security, quality of service (QoS), and availability capabilities while lowering the network’s total cost of ownership.
Cisco offer Cisco Catalyst 2960 Switches with LAN Lite software.

SwitchesConfiguring SNMP Version 3 in a Cisco Catalyst Switch is bit more complicated compared to SNMP v1 and v2. But after configuring SNMPv3 you can relax as the SNMPv3 provides more security by adding authentication (username and password) as well as encryption to the protocol.
What is SNMPv3 ?Simple Network Management Protocol version 3. The specification for this Full Standard protocol is published in RFCs 3410 and 3418. SNMPv3 provides a Full Standard administrative framework (authorization, access control, etc.) and a remote configuration/administration MIB. Also check the SNMPv3 documentation from Cisco Systems.
How to configure SNMPv3 in a Cisco Catalyst Switch ?
First we begin with configuration of SNMPv3 on the Cisco Catalyst Switch by creating a SNMP “view”. A “view” defines what information can be accessed by the SNMP user/group when they query the SNMPv3 enabled Cisco Catalyst Switch. In the below example we will create “view” called ITKEView. We will enable “system” , “internet” and “interfaces” SNMP OIDS on the Cisco Catalyst Switch.
ITKE(config)# snmp-server view ITKEView internet includedITKE(config)# snmp-server view ITKEView system includedITKE(config)# snmp-server view ITKEView interfaces included

Make sure the Cisco Catalyst 6513 Switch is installed with the redundant power supply and they are connected to two different power sources. Suppose one power source fails then the other source can take care of the Cisco Catalyst 6513 Switch while the IOS upgrade is going on.

SwitchesIn the first series I was talking about the TFTP severs, now let’s proceed further, one more key thing you must consider before starting an IOS upgrade for a Cisco Catalyst 6513 Switch with Supervisor Engine SUP720 is the Compact flash memory. The Supervisor Engine SUP720 comes with two slots for memory. Recommended part number

MEM-C6K-CPTFL256M
|
Cat6500 Sup720 Compact Flash Mem 256MB |
The Compact flash memory is required in order to avoid any failure IOS file upload through TFTP server. As before uploading the file the current IOS file is deleted from the boot flash memory of the switch. Before starting the IOS upgrade in the Cisco Catalyst 6513 Switch with Supervisor Engine SUP720 issue a boot command to boot from the flash memory if the Cisco Catalyst 6513 Switch with Supervisor Engine SUP720 fails to boot from the boot flash memory by issuing following command.
Note: the Compact flash memory is inserted in the slot 1 of the Supervisor Engine SUP720.

TFTP ServerToday I successfully upgraded the IOS for a Cisco Catalyst 6513 Switch with Supervisor Engine SUP720. Couple of years I faced some problems while I was upgrading the IOS for Catalyst 6513 Switch. In this series I will try to focus on the things to be considered before upgrading an IOS in Cisco Catalyst 6513 Switch.
First and foremost is the TFTP server. The main problem you face is the file size limitations with the TFTP servers. Most of the TFTP servers won’t support more than 30 MB of IOS file to transfer. At that time I was using Solar Winds TFTP server which is an excellent software but cannot support more than 30 MB. The IOS transfer failed exactly after 30 MB of transfer. I was worried what might be the problem, after careful observation I figured out the problem lies with the Solar Winds TFTP server .Then I tried Cisco’s old TFTP server but the same problem. Later on I figured out TFTP server can support more than 30 MB of file transfer.
Hence after changing to 3Coms 3CDaemon Server & PacketTrap pt360 Tool Suite FREE edition I could able to transfer the IOS files more than 30 MB. So the main point is to make sure your TFTP server can support more than 30 MB of file transfer as always the image file for Cisco Catalyst 6513 Switch is more than 30 MB in size. Presonally I would recommend the TFTP server from PacketTRAP pt360 Tool Suite
Things to be considered for IOS upgrade series 2

ZFWGuess what your Routers support zone-based policies, which really helps with multi-interface restrictions (rather than just one outside & one inside interface with individual access list applications). Likewise, it now supports application inspection to catch those scandalous peer-to-peer programs.

Cisco IOS® Software Release 12.4(6)T introduced Zone-Based Policy Firewall (ZFW), a new configuration model for the Cisco IOS Firewall feature set. This new configuration model offers intuitive policies for multiple-interface routers, increased granularity of firewall policy application, and a default deny-all policy that prohibits traffic between firewall security zones until an explicit policy is applied to allow desirable traffic.
