ASA 5585-X Update the CX SSP Module
KB ID 0001005 Problem Every piece of documentation I found on upgrading CX SSP modules was for doing so on models other than the ASA5585-X. The (current) latest CLI guide says; “For the ASA 5585-X hardware module, you must install or upgrade your image from within the ASA CX module. See the ASA CX module documentation for more information.” Yeah good luck finding that! Solution Before I saw the information above I tried...

ASA Upgrading and Imaging a Hardware CX Module
KB ID 0001025 Problem Last time I had to do one of these the process was very straight forward, one command and the ASA got its new image from FTP, extracted it, and then installed it. I had a CX module fail last week, and Cisco shipped me out a replacement. After installing it and running the setup, I needed to upgrade it (it will be managed by PRSM). It was running version 9.0.2 (probably been on the shelf a while!). And every time...
Configure Your Firewall for SNMP
KB ID 0001034 Problem Had a requirement to let SNMP traffic though a firewall this week, I have a client that has both SolarWinds and SCOM, and they need to monitor the external Citrix ADC load balancers. For SNMP we simply need UDP ports 161 and 162 (See below) but SolarWinds maintains ‘ping’ connectivity to the monitored assets, so ICMP also needs to be open. Inbound Ports Outbound Ports Solution As my ‘weapon of...
