In 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.

Today 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
