Hi team good day could someone help me, I'm trying to configure the device (F5), but when I add the nodes I get the following message: "Unknown (Enabled) - Node address service checking is enabled, but result is not available yet" The thing is that when I access via cli (ssh) and execute a telnet to the port it is successful, but the service is in a blue state. I send screenshots of the error: Could you help me please, it's the first time I've configured it, thank you: successful connection telnet to port 7500 via cli (ssh): echo "" | nc -v -w 1 10.154.104.6 7500 Ncat: Version 6.40 ( http://nmap.org/ncat ) Ncat: Connected to 10.154.104.6:7500. <{25:20230612144900;27:99;31:1;26:Error;28:Format Error;32:1}Ncat: 1 bytes sent, 66 bytes received in 0.02 seconds.

In our Big IP ASM, the server CPU is operating at high load during specific time periods. I have checked and confirmed that cron jobs are running at different times. Even though the traffic is not high, this issue still occurs. What could be the cause of this?106Views1like4CommentsCentral Manager Bug ID 1586501
Hello, I have installed Central Manager 20.3 under vmware and I receive the following alert: Instance of mbiq-ado-feature is down. According to the Bug ID 1586501, I need to run the following scripts: one to identify impacted instances (find_broken_telemetry_instances.sh) and a second script to fix telemetry streaming to Central Manager (update_cm_logger.sh). Where do I get these scripts?24Views0likes1CommentWhich runs first iRULE or PolicyLTM(With ASM being applied)
Hello all Its well known by the K16590 that LTMPolicies will run before the irules using the same event, for example HTTP_REQUEST in an irule and "at request time" in LTMPolicy. But regardless the order, if the LTM Policy says to enable ASM policy the BIG-IP would still return and process the irule or the traffic would be sent to ASM policy for process leaving the irule whitout a match/process ? In my understanding the LTM Policy would be read first, after that the irule and then the traffic sent to ASM Policy. But i'm not having my irule redirects occuring. In this case of configuration: when HTTP_REQUEST { if {[HTTP::uri] starts_with "/region1/abc"} { HTTP::redirect https://[getfield [HTTP::host] ":" 1][HTTP::uri] } elseif {[HTTP::uri] starts_with "/region2/abc"} { HTTP::redirect https://[getfield [HTTP::host] ":" 1][HTTP::uri] } elseif {[HTTP::uri] starts_with "/region3/abc"} { HTTP::redirect https://[getfield [HTTP::host] ":" 1][HTTP::uri] } elseif {[HTTP::uri] starts_with "/region4/abc"} { HTTP::redirect https://[getfield [HTTP::host] ":" 1][HTTP::uri] } else { # do nothing } } ltm policy LTM_POLICY_ASM_MYSITE { controls { asm } requires { http } rules { MYSITE { actions { 0 { asm enable policy /Common/ASM_MYSITEWAFPOLICY } } conditions { 0 { http-host values { www.mysiteexample.com.br mysiteexample.com.br } } } } default { actions { 0 { asm enable policy /Common/ASM_MYSITEWAFPOLICY_MISC } } conditions { 0 { http-uri contains values { miscelaneous } } } ordinal 1 } no_asm { actions { 0 { asm disable } } ordinal 2 } } status published strategy first-match }50Views0likes2CommentsiRule for host rewriting between nodes
Hello, I have a virtual server that offers 4 services on the same nodes in openshift: service1.dns.com >> A Record (Virtual Server IP 192.168.1.200) service2.dns.com >> A Record (Virtual Server IP 192.168.1.200) service3.dns.com >> A Record (Virtual Server IP 192.168.1.200) service4.dns.com >> A Record (Virtual Server IP 192.168.1.200) * Virtual Server IP 192.168.1.200 - Pool / Node 1 - 192.168.50.100 / Node 2 - 192.168.50.101 Relevant configuration > SSL Profile Client, SSL Profile Server, iRule (Host rewrite) --- In the given iRule, I must rewrite the external DNS host to a host that Openshift is able to handle to avoid 404 errors. If it balances on node1 it must be rewritten in one way, and if it balances on node2 it will be rewritten in another way. A first configuration has been made with the following definition, but the headers are not being rewritten correctly: when LB_SELECTED { switch -glob [string tolower [HTTP::host]] { "service1.dns.com" { if { [LB::server addr] eq "192.168.50.100" } { HTTP::header replace Host "service1.ocp.site1.com" } elseif { [LB::server addr] eq "192.168.50.101" } { HTTP::header replace Host "service1.ocp.site2.com" } } "service2.dns.com" { if { [LB::server addr] eq "192.168.50.100" } { HTTP::header replace Host "service2.ocp.site1.com" } elseif { [LB::server addr] eq "192.168.50.101" } { HTTP::header replace Host "service2.ocp.site2.com" } } "service3.dns.com" { if { [LB::server addr] eq "192.168.50.100" } { HTTP::header replace Host "service3.ocp.site1.com" } elseif { [LB::server addr] eq "192.168.50.101" } { HTTP::header replace Host "service3.ocp.site2.com" } } "service4.dns.com" { if { [LB::server addr] eq "192.168.50.100" } { HTTP::header replace Host "service4.ocp.site1.com" } elseif { [LB::server addr] eq "192.168.50.101" } { HTTP::header replace Host "service4.ocp.site2.com" } } } } Any help is appreciated Best regardsSolved95Views0likes8CommentsWhat is the best practice to deploy single Tenant in F5 rseries?
Hi, we are going to deploy new rseries 5k with single Tenant. What is the best practice to setup? I plan to setup like below, can someone please advise whether it is correct or not? And I have question on auto disk space and memory allocation. Thanks in advance! Allocate all the disk space to this large single tenant Allocate all the memory to this single tenant within the tenant, set "Large" to "Mgmt" module for the rest modules: LTM, GTM , ASM , set "Normal" under Resource Provisioning". Seems the system automatically allocate disk space and memory to each module. Based on the amount of disk space and memory allocated to these modules, seems there are still a lot spare diskspace and memory. Will these modules automatically share the rest spare diskspace and memory when necessary?Solved78Views0likes2Comments
