R&S specifically.
I’m loaded up pretty heavily on classes this semester. I’m trying to finish up my BS in IS Management. The workload as I get into 400 level classes has increased significantly. I have a number of projects that have fallen to the side including: Learn and understand nRF24l01 radios for Arduino to RPi communication. Cobra […]
I’ve had all kinds of problems with this tonight. Luckily, none have affected the operating stack which is a pair of 3750’s. Not E’s or V2’s but original 3750’s. I’m trying to add a 3750X which is supposed to work just fine. I’ve done all kinds of things including about 10 different versions of 12.2.55 […]
It’s taken me a while but I finally have another review to provide. I was due for my CCNP recert so I decided to go for the Switching test, 642-813. I started with this book: My focus was on the switching section so this review really only addresses that part. I’ve been taking Cisco tests […]
Wow…4+ years later and I’m finally posting part 2. Yep, the original config didn’t work quite right but I did get it working. Here’s the result: On the Cisco switch: interface Port-channel98 no ip address switchport switchport trunk encapsulation dot1q switchport mode trunk ! interface GigabitEthernet8/5 no ip address switchport switchport trunk encapsulation dot1q switchport […]
That’s a mouthful. I’ve been having a hard time figuring out how to successfully transfer images to the Standby ASA’s flash from the Active’s CLI. Finally figured it out. Here’s the syntax: failover exec standby copy /noconfirm tftp://{ip address}/{file name} disk0:/{file name} Without the /noconfirm it’ll fail. You also need a standby ip address on […]
I previously posted about some luck I had getting IPSEC VPN to work from my iPhone to my IOS router/firewall. That post is now kind of useless because the source blog disappeared about a year ago. So, in order to make this useful again I’m posting my full IOS code (obfuscated for obvious reasons). Change […]
Seems my original post about the AnyConnect Essentials license is still quite popular. So why not capitalize on that! 🙂 The license does work as advertised. It’s a replacement for the IPSEC based client that Cisco seems to have stopped development on. I’ve been using it in numerous situations and it works great! I just […]
Ran across this tonight. Someone had entered a prefix-list with the name “at& ;t” instead of “at&t” (wordpress didn’t like it either so I added the space between the p and the ; but they should really be together. Oddly enough, IOS wouldn’t allow the bad line to simply be deleted. The “;” had to […]
I’ve been trying to figure out why a pair of Cisco IPS (AIP-SSM in this case) wouldn’t auto-update signature files or connect to the new Global Correlation feature. The management interfaces were located on a subnet that was between the firewall and the internal L3 switch. The internal LAN’s are on the other side of […]
“It works similar to access-list in that if you have any SNMP View on certain MIB trees, every other tree is denied inexplicably.” 🙂
