Cisco Live US 2018


I am writing this late, so many details of the week escape me, but I knew I wanted to write something.

I attended Cisco Live US 2018 in Orlando this year. I had so much anticipation leading up to it from the moment it got approved at work. I had first learned of Cisco Live while attending the Cisco Network Academy at my local college. It seemed like a dream that I would never have.

Alas, it came and went. I stayed at a hotel that was about a 15 minute walk from the conference, which was nice. I got ripped off by an Uber driver for the first time while I was there too, luckily I got refunded.

I took my CCNP Switch exam for the first time on Sunday before the conference. I unfortunately got a 706 and needed a 790 to pass. I am sure I could have studied more to pass, and plan on retaking it soon.

After that point, the conference itself felt like a whirlwind. The conference was SO BIG. The sessions were great and I learned a lot. The World of Solutions was also quite impressive. Throughout the entire week I felt like I barely scratched the surface of what CLUS had to offer, and that feeling came early and remained tangible.

I met some great people and got to go to some great parties. I got to see Ludacris at a nearby House of Blues. I got to go to a Top Golf for the first time. I got to go to a Main Event for the first time (the VR zombie game was insanely awesome). I got to go to Universal Studios for the first time, which was a great time, especially seeing CAKE.

Honestly, the thing that was most disappointing was the fact that coffee and snacks were at scheduled times. I WAS EXPECTING READILY AVAILABLE COFFEE ALL DAY. The staff literally set up the coffee stations about 30 minutes before the scheduled "coffee time" and then covered it up with a sheet and stood there until the scheduled time. That was unfortunate because it seemed like every time I wanted some coffee, I either couldn't find any, or they told me they couldn't serve it yet.

Ultimately, I am not sure if I plan on trying to go every year, but rather maybe every two or three years.

CHI-NOG 08


I will be attending CHI-NOG 08 this year. I am super excited about going to learn some new things and meet some great networking folks.


Snippet from CHI-NOG's website about what it is:

CHI-NOG is the first and the only Chicago based Network Operators Groups. The group was started by network engineers and network architects to create a community, to learn from each other and meet others. We get away from our keyboards and screens to meet in person every year bringing in speakers from all over the US to learn and have a beer with them. CHI-NOG is vendor neutral so we aren’t trying to sell you anything, but you do get a pretty awesome t-shirt each year for attending.


I went last year to CHI-NOG 07 and loved it. The venue was beautiful, the speakers were great, and I learned a ton. The vendor hall afterwards was small and intimate, so you could ask all the questions you wanted. All of the vendors seemed pretty laid back instead of being super sales-y.
Here are some videos from CHI-NOG 07: http://chinog.org/meetings/chi-nog-07/chi-nog-07-videos/

How to Upgrade a Cisco Switch IOS via TFTP


Cisco Switch IOS Upgrade Procedures via TFTP
Put the new image in your TFTP server root directory.

1. BACKUP CURRENT CONFIGURATION

sw1#copy running-config tftp: 
Address or name of remote host []? <Your TFTP Server IP address>
Destination filename [savant-rfd-sw1-confg]? <Enter>
!!!!! 19909 bytes copied in 0.872 secs (22831 bytes/sec)

2. DELETE OLD IOS IF NOT ENOUGH SPACE ON FLASH

Some switches do not have enough Flash storage space to hold two IOS images, in these cases you must delete existing IOS image from Flash before transferring the new image to the switch, because because if you don’t the TFTP file transfer will fail. If there is enough space to hold both images, then skip to Step 3.

sw1# delete c3560-ipbase-mz.122-25.SEE3/c3560-ipbase-mz.122-25.SEE3.bin

Note: You will need to change the text to delete the image that is on your switch. This removes the image from the flash, but here will still be a directory called in Flash that has the same name as the image, but the image will be gone, leaving you enough space on flash to transfer the new image to the flash.

3. COPY NEW IOS IMAGE FROM TFTP TO FLASH

sw1#copy tftp flash:
Address or name of remote host []? <Your TFTP Server IP address>
Source filename []?c3560-ipbasek9-mz.122-55.SE9.bin
Destination filename [c3560-ipbasek9-mz.122-55.SE9.bin]? <Enter> 
Accessing tftp://10.0.0.0/c3560-ipbasek9-mz.122-55.SE9.bin…

Note: You will need to change the input to match what you are wanting to do. Also, the upload process may take a while…

4. AFTER TFTP TRANSFER IS COMPLETE, SET SWITCH TO BOOT TO NEW IMAGE, MUST BE EXACT
sw1(config)#boot system flash:c3560-ipbasek9-mz.122-55.SE9.bin

Note: Change the input to match what you uploaded to Flash. Must be in global config mode. Also, you can have more than one image specified in the boot system config. The system will try to boot to the first in the list, if it can not, it will try the second in the list. It may be helpful if you have both the old and the new image on Flash to specify the old as a fallback.

5. VERIFY NEW BOOT CONFIGURATION

sw1#show boot BOOT path-list : flash:c3560-ipbasek9-mz.122-55.SE9.bin

Note: You need to see EXACTLY the image you uploaded to the Flash on the first line of the results before you reload.

6. COPY RUNNING CONFIGURATION BEFORE RELOAD OR YOUR WILL SWITCH WILL NOT BOOT PROPERLY

sw1#copy running-config startup-config

7. ISSUE RELOAD COMMAND

sw1#reloadProceed with reload? [confirm] <Enter>

8. VERIFY SWITCH BOOTED TO NEW IOS AFTER RELOAD

sw1#show version
...omitted...
System image file is "flash:/c3560-ipbasek9-mz.122-55.SE9/c3560-ipbasek9-mz.122-55.SE9.bin"
...omitted...


9. COPY RUNNING CONFIGURATION TO STARTUP CONFIGURATION

sw1#copy running-config startup-config


GOOD LUCK!!!
