TCL error: _cgc_pick_clientside
Hi, in an ASM-LTM (Perimeter) Setup I see frquently the following logs: ***err: tmm3[19962]: 01220001:3: TCL error: _cgc_pick_clientside - unknown cgc sni: f5-bei1.xxxx.xx (line 49) invoked from within "CGC::sni $tls_servername"*** Any idea what this TCL error causes? The clientssl is quite Basic: one certificate chain, no Server Name set. Thanks, Rolf

An Irule for Client Ssl Profile that Allows Unassigned TLS Extension Values (17516)
Hello Community, I have a requirement to allow enriched https header enrichment. The SSL negotiation (I'm doing ssl termination on F5) fails because the enriched header from client contains reserved tls extension values. (https://www.iana.org/assignments/tls-extensiontype-values/tls-extensiontype-values.xhtmltls-extensiontype-values-1). The Client Hello request in the SSL Handshake was captured and contained an Extensions list, which included a reserved TLS Extension value (17156), which the F5 isn't presenting in Server Hello. I need an irule that can allow that Extension to be added on the client ssl profile so the ssl handshake doesn't fail.
SSL Renewal / Orchestration?
What are people who use F5 LTM using for SSL ordering/orchestration/renewal? We don't have BIGIP but are running BIGIP Os 16.x.x and I see some integration in the webUI for GOdady, Digicert., etc.. But we mostly use Globalsign / Globalsign API for cert ordering. I'm hoping to have an easy/secure way to renew/order/install certs to the F5 vCMP guests from Globalsign
SSL Server Side Profile
I am looking for some help with SSL Server Profiles. I am looking to decrypt/ASM/re-encrypt If I connect directly to my backend server, everything works I have installed CA cert and configured my SSL client. If I set my backend connections to HTTP and do not apply a SSL server profile, everything works If I then add a custom SSL server, with a parent profile of serverssl I then switch to a pool of HTTPS and get a HTTP error 404 . The requested resource is not found If I remove the server SSL profile and move back, everything is fine. I'm unsure what if anything I am missing: Should I under configuration >> certificate >> key Server Authentication Server certificate >> required >> Trusted cert authorities (what cert do I need here) Any help would be greatly appreciatedQuestion on configuring SNI clientSSL Profile
Hi Experts , I have a question on configuring the SNI SSL profile .Suppose say I have 3 different certificate and 3 SSL profile to be attached to the VIP to configure SNI . https://www.securesite1.com ClientSSL1 > Default SSL Profile for SNI https://www.securesite2.com ClientSSL2 https://www.securesite3.com ClientSSL3 To enable SNI, we configure the Server Name and Default SSL Profile for SNI will be checked on an SSL profile of ClientSSL1, and then assign the profile to a virtual server. How about on other 2 SSL profiles ClientSSL2 & ClientSSL3 ? For other SSL profiles do I need to type the name for the HTTPS site in the Server Name box ? or it can be left blank ?Certificate expiry monitoring
Hello Everyone! Would like to ask how you monitor your certs in your F5s? we would like to monitor the certificate expiry on our F5. I am checking our logs on ltm but it seems that the normal certs are not being logged. I only see cert bundles. Can you share how you monitor the certs expiry on f5?Renew BIG-IP device SSL certificate
hello Team, I am going to renew our BIG-IP device SSL certificate, but this time we have GTM so we also need to update the GTM side. This is what I am planning Renew the BIG-IP device SSL certificate via cli on config/httpd/conf/ssl.crt/server.crt Restart the httpd service I am planning to update the GTM via GUI DNS -> GSLB -> Servers -> Trusted Server certificates -> Import -> Append -> paste the new cert Restart the big3d and gtm service Question is, is this correct way? also will this also update my cert on big3d (/config/big3d/client.crt)? If not, do I need to update the cert on big3d? Thank you!INFORM: Entrust CA will be untrusted in Chrome after Oct 31, 2024
If you manage certs from Entrust in your environment, this will impact your Google Chrome users, so intermediate certs will likely need to be bundled to handle this in your clientssl profiles OR if you control all the clients you can assure that explicit trust in the clients is enabled for Entrust CAs. Google details on the situation
