tmsh script
3 TopicsInstall rpm packages using tmsh
Hi everyone, I’m trying to install the F5 Cloud Failover Extension (CFE) on my BIG-IP system, but I’m struggling to properly install the RPM package so that it appears under iApps → Package Management LX. Here’s what I have done so far: Successfully downloaded f5-cloud-failover-2.1.3-3.noarch.rpm Tried installing the package using rpm -ivh f5-cloud-failover-2.1.3-3.noarch.rpm. Restarted the REST API service using tmsh restart sys service restjavad. Despite these steps, the package does not appear under iApps → Package Management LX Also when I reinstall the package I get "package f5-cloud-failover-2.1.3-3.noarch is already installed" Is there a specific command to install RPM packages via TMSH so they are properly recognized? Or is there another step required to make the extension available? Thanks in advance for any insights!61Views0likes2CommentsRemoving AAM/WAM for a successful upgrade
If you are wanting to upgrade to version 16 or 17 of BIG-IP, one thing that can cause your config not to load, is any element of AAM/WAM/WOM. As I discovered via a customer of mine, even removing all AAM/WAM items from traffic objects is not enough. While I know how to identify things in the conf files and can see them in iHealth, that doesn't help Admins in the field assess if this is an issue for them, and if it is, how to document what needs to be changed for the necessary approvals. With some help, I wrote this knowledge article to meet these needs as well as provide a way to quickly make the changes - https://my.f5.com/manage/s/article/K000149084 I am sharing this in the forum to not only advertise this, but explain some of the commands and help the community understand how they might be used for other tasks. From spending time running a few BIG-IPs myself in a prior life and working with hundreds of customers, I knew that my solution needed to address partitions and even iApps. My coworker Fernando C provided me the syntax to crawl every partition and I quickly found ways to morph that into this document. Lets take a look at the syntax that can read the lan TCP profiles in the Common partition and then see the changes needed to read all partitions. In order to filter the results a bit better we run these from bash so that we have access to a number of tools like grep, awk, sed, etc. # Return all virtual server names in Common that use a TCP Profile from wam or wom (aka AAM) # grep to find the profile prefixes and then piping that to AWK to grab the third word in the output of each line tmsh list ltm virtual one-line | grep -E "(profiles.*(w(a|o)m-tcp-lan*))" | awk '{print $3}' This simply returns the virtual server name without the partition name. Now to read all partitions, the tmsh portion of the command has to change. Specifically, we pass the -c option to tmsh to tell it to run multiple commands. When you enter tmsh, by default you are in the Common partition, so we have to back out to the root. Because we are in the root directory, we need to add the recursive option to read all subfolders which in this case are the partitions. #Read all partitions and filter for virtual servers that use the wam/wom TCP profiles on the lan or server side tmsh -c 'cd /; list ltm virtual recursive one-line' | grep -E "(profiles.*(w(a|o)m-tcp-lan*))" | awk '{print $3}' Now the output is the partition name and virtual server name, or if iApps are involved, the appservice name as well. You can take the output from the first command and pass it to xarg to use your output as a variable in a command to execute. CAUTION, the following command will attempt to make changes to your config. #Read all partitions and filter for virtual servers that use the wam/wom TCP profiles on the lan or server side then insert new profiles and delete the original profile #This will cause an error tmsh -c 'cd /; list ltm virtual recursive one-line' | grep -E "(profiles.*(w(a|o)m-tcp-lan*))" | awk '{print $3}' | xargs -t -I vsName tmsh modify ltm virtual vsName profiles add { f5-tcp-lan { context serverside } } profiles delete { wam-tcp-lan-optimized } If you run this command, it will error out, because without the proper syntax, tmsh assumes you are referencing objects in the /Common partition and as a result it will help you by implicitly adding that to the beginning of every object in your xarg command. I added the -t option to xarg to output the command that it will execute. To correct the syntax error, in the awk command, you add a forward slash and now tmsh will treat your command as if you have explicitly declared the partition name for every object. Caution - This will make changes to your configuration, very fast... #Read all partitions and filter for virtual servers that use the wam/wom TCP profiles on the lan or server side then insert new profiles and delete the original profile #CAUTION - This will make changes to your system. tmsh -c 'cd /; list ltm virtual recursive one-line' | grep -E "(profiles.*(w(a|o)m-tcp-lan*))" | awk '{print "/" $3}' | xargs -t -I vsName tmsh modify ltm virtual vsName profiles add { f5-tcp-lan { context serverside } } profiles delete { wam-tcp-lan-optimized } When I first hit the wall with xarg beyond the /Common partition, I did not realize what the fix was. However my OCD wanted to see a slash in front of the partition name and I had modified the awk to add it, but had given up on the xarg to modify things outside of /Common. It wasn't until I went to show the error to a peer, Chad T., that I discovered I stumbled upon the proper syntax, and realized I could simplify the instructions quite a bit. Where I would love some help from the community would be on ways to crawl the iApps to quickly disable Strict Updates. The xarg commands to modify/delete objects associated with an iApp will fail if the default setting of "Strict Updates" is enabled. Hope this helps, Carl143Views3likes3CommentsNeed help on CLI command to fetch < VIP Name + current connections >
Hello Experts , I need help in modifying below command which should also give me information of VIP name along with current connection . show ltm virtual recursive all | grep 'Availability\|Current Connections' As you can see this command only gives info of current connection but it will not tell which VIP has the current connection value ... blue.whale@(F5-BIGIP-ACT)(cfg-sync In Sync)(Active)(/Common)(tmos)# show ltm virtual recursive all | grep 'Availability\|Current Connections' Display all 1942 items?
